| `/sales-viral-loops` | Viral Loops — referral & viral-marketing campaign builder (templates for referral programs, pre-launch waitlists, giveaways, milestone/Robinhood-style referrals, ambassador leaderboards) + embeddable widget; REST API (`app.viral-loops.com/api/v3`, per-campaign `publicToken`, `POST /campaign/participant` with `referrer` attribution) + webhooks (participant/referral-count/convert/reward, no documented HMAC) + two-way Zapier; scales by participants (Build ~$49/mo, Accelerate ~$229/mo) |
| `/sales-growsurf` | GrowSurf — referral AND affiliate program software for SaaS/B2C product teams; in-product JavaScript SDK + embeddable Elements, REST API (`api.growsurf.com/v2`, Bearer; key locked until email-verified, rotates on first login), 7 webhook events (participant/commission/payout/fraud; 5 per program, `isReferrer` double-sided, no documented HMAC), Stripe-native referral triggering, affiliate commission tracking + refund/chargeback adjustments + automated 1099 filing; participant-based pricing (Startup/Business/Custom), API gated to an active paid subscription |
| `/sales-rafflepress` | RafflePress — WordPress giveaway & contest plugin (by Awesome Motive) for viral list growth: drag-and-drop builder, 30+ bonus-entry actions, refer-a-friend (+10 entries), hosted landing pages, winner picker, fraud protection. WordPress-only (no REST API); automation via outbound webhooks (JSON/FORM, fields fullname/email/giveaway_id/sign_up_date, no HMAC, social-action data NOT sent), Zapier "New Contestant Created" trigger, 15+ native ESPs, Uncanny Automator, WP hooks + URL prefill; free Lite + one-time Pro (~$299 single / ~$349 unlimited) |
| `/sales-shortstack` | ShortStack — standalone SaaS campaign platform for contests, giveaways, sweepstakes, quizzes, refer-a-friend, instant-win, landing pages + social promos, with lead capture, auto winner selection, analytics. Entries API (`entries.shortstack.com`, `Authorization: Token token=`, per_page ≤5000, `{data:[...]}`) + SIGNED real-time webhooks (`X-Ss-Signature` HMAC of body+secret) + Webhooks management API + native Mailchimp/HubSpot/Salesforce + Zapier; free-forever plan + paid tiers |
| `/sales-sweepwidget` | SweepWidget — cheap, high-limit giveaway/contest/sweepstakes builder with 100+ entry methods across 30+ social platforms, refer-a-friend, leaderboards, instant rewards/coupons, list capture (unlimited entries + contests on all plans). Read+write REST API (`sweepwidgetapi.com/sw_api/`, `Authorization: Bearer` or `api_key`, 50 rows/page via `page_start`; reads entries/users/winners/giveaways, writes create-giveaway/new-entry/create-entry-method/create-prize/create-reward) + HMAC-SHA256 SIGNED webhooks (`X-SweepWidget-Signature`; entry_submitted/task_completed/all_entries_completed) — both Enterprise-plan-gated; client-side JS callbacks + native ESP/Zapier/WordPress/Shopify on lower tiers; free-forever plan |
| `/sales-kingsumo` | KingSumo — cheapest, dead-simple viral giveaway tool (from the AppSumo team) for email-list growth, sold one-time/lifetime-deal; ships as a hosted app + a separate KingSumo Giveaways for WordPress plugin. Unlimited giveaways + viral bonus entries (refer-a-friend, social shares/follows, YouTube/podcast subscribe), Smart Auto-Emails, multiple prizes. Automation is outbound-only: native SendFox+Zapier (Free) / Mailchimp+ConvertKit-Kit+Klaviyo (paid); Zapier is TRIGGER-ONLY (New Contestant/New Giveaway, no actions), "Webhooks by Zapier" only; a "fully-featured API" (OAuth, paid) is advertised but has NO public docs. No custom domain/CNAME, shares are unverifiable, giveaways attract freebie-seekers |
| `/sales-referral-factory` | Referral Factory — no-code referral program builder (100+ branded templates: single/double-sided, invite-only, refer-to-win), reward issuing (cash/gift cards/Stripe/commissions, no direct bank payout); clean REST API (`api.referral-factory.com/api/v2`, Bearer, one token/account) — `POST /users` with `referrer` attribution, `PUT /users/qualification` to make a reward due, `/rewards/issue|cancel`; in/outbound webhooks (no documented HMAC) + native HubSpot/Salesforce/Stripe/Zapier/Make/n8n; scales by users (Basic ~$200/Pro ~$400/Enterprise ~$1,000, white-label/custom domain Pro+) |
| `/sales-tolt` | Tolt — affiliate-program software for SaaS startups and indie founders; branded custom-domain portal, partners/groups, tracking links + promo codes, plan-capped UI-only commission flows, payouts (PayPal/Wise/bank/wire/crypto) with W-9/W-8 + 1099 filing, 2-way Stripe/Paddle/Chargebee sync; REST API (`api.tolt.com/v1`, Bearer, unscoped keys, cursor pagination, 25 rps) + `tolt.js` SDK + the category's first **native MCP server** (`mcp.tolt.com`, 8 tools incl. `commission_reconciliation`). **No webhooks at all** — poll instead; invalid API key returns **500 not 401**, three different error envelopes across docs and live API, and no rate-limit headers. Priced by affiliate-attributed revenue/month, not seats; entry tier is manual payouts only, auto-payouts add a 2% fee |
| `/sales-affonso` | Affonso — budget affiliate/referral software for SaaS and the **deepest automation surface in the Stripe-native cohort**: 78 REST endpoints (`api.affonso.io/v1`, Bearer, **9 scoped key permissions**, page/limit pagination), **21 HMAC-SHA256-signed webhook events** (`X-Affonso-Signature: t=…,v1=…`, `whsec_` secret, 5 retries over ~2h), an **MCP server** (`api.affonso.io/mcp`, 18 tools, OAuth 2.1 or API key), TypeScript SDK (`affonso-node`) and CLI (`@affonso/cli`). `POST /v1/conversions` auto-calculates commission and **requires `external_event_id`** as a stable idempotency key, so a replayed Stripe webhook can't double-pay an affiliate. Native Stripe/Paddle/Polar.sh/Creem.io/Dodo ingestion; 13 payout methods; Risk Center fraud detection; embeddable partner dashboard on **every** tier. **The MCP server is gated to the second tier while REST API, webhooks, SDK and CLI all work on the entry tier** — so cheapest-plan + Claude Code means the CLI. Event tracking, postback URLs, multi-level commissions, pay-per-lead, managed payouts and Segment are also second-tier; no native HubSpot/Salesforce connector; no self-serve SSO on any tier. Priced by affiliate-attributed revenue/month, **quoted in EUR while the revenue caps are in USD** |
| `/sales-promotekit` | PromoteKit — **cheapest credible entry in the Stripe-native affiliate cohort**: genuinely free tier (first 3 referrals), then a flat fee with **no transaction fees**. Ships a real **15-endpoint REST API** (`https://www.promotekit.com/api/v1` — note `api.promotekit.com` is the dashboard app, **not** the API) and **5 Svix-signed webhook events**, both **Pro-gated**. Its defining trade: it **tracks but does not pay** — no W-9/W-8, no 1099s, and the **payouts API is read-only**, so PayPal Mass Payments / Wise Batch Payments stay manual. Referrals track in **Stripe live mode only**; subscriptions need the referral in `subscription_data.metadata`. Stripe-only billing; no CRM connector, MCP, SDK or CLI. |
| `/sales-refgrow` | Refgrow — affiliate/referral software for SaaS and the **only budget Stripe-native tracker that embeds the affiliate dashboard inside your product** (`` + `scripts.refgrowcdn.com/page.js`), so affiliates who are already users never leave the app. **Broadest billing ingestion in the cohort — Stripe, Paddle, LemonSqueezy, Polar and Dodo Payments.** 0% transaction fees and unlimited affiliates/revenue on every tier, with the whole developer surface on the entry plan: REST API (`refgrow.com/api/v1`, Bearer `rgk_`, unscoped, full CRUD, `limit`/`offset` + `pagination.has_more`), **4 HMAC-SHA256-signed webhook events** (`X-Refgrow-Signature: sha256=…`, 3 retries), an **18-tool MCP server** (`@refgrow/mcp`) and a **CLI** (`@refgrow/cli`). Program count and AI Recruiter quota are the only tier gates. **It pays affiliates** via PayPal/Wise — manual or fully automatic, with a state machine preventing two in-flight payouts and auto-refund on provider rejection — closing the gap PromoteKit leaves open, though it files no 1099s. Attribution runs coupon match → checkout metadata → `client_reference_id` → subscription metadata → email. **Its defining caveat: the vendor's docs contradict the shipped product in ~a dozen verified places, all failing silently** — the JWT-SSO widget embed 404s and was never built, the documented server-side attribution call always 400s, two cookie names, three rate limits, two error envelopes, and four MCP tools that do not exist. A source-verified client bug also **kills click attribution outright on any multi-part TLD** (`.co.uk`, `.com.au`). Payouts and commission rules are UI-only; `POST /conversions` has no idempotency key. No free tier despite the vendor's own blog claiming one |
| `/sales-leaddyno` | LeadDyno — affiliate tracking & management for **ecommerce storefronts** (Shopify with line items + Recharge subscriptions, BigCommerce, WooCommerce, Ecwid, Squarespace, Cratejoy) alongside Stripe/Chargebee/Recurly/PayPal — the ecommerce-native peer of Refersion and Tapfiliate rather than the Stripe-native cohort. MLM chains, affiliate groups, sub-IDs, white-labelled dashboard on your own domain. **62 REST endpoints on `api.leaddyno.com/v1`, and the API is not plan-gated** (private key as a `key` parameter; 200 req/min but no `X-RateLimit-*` headers on any probe). **Two pricing models are live at the same four prices**: current plans meter **Active Affiliates** (50/150/500/∞ — everyone *not archived and not pending*, so dormant sign-ups consume the cap and `POST /affiliates/{id}/archive` is the cost lever), while **legacy Starter/Plus/Pro/Premium plans meter unique monthly website visitors** with $0.10–$0.001 per-visitor overage, so an ads spike inflates the bill with no affiliate involved — and the public pricing page shows only the current model. **No event webhooks at all** (integrations poll; the sole webhook is an outbound payment webhook whose SHA-1 HMAC signs only the affiliate's *email*, protecting neither the amount nor against replay). All `LD_*` tracking cookies are set on LeadDyno's domain, making them **third-party** from your storefront — the vendor's own KB concedes attribution then fails, which is the root of most missing-referral complaints; fix server-side or with coupon codes (not auto-created in the store). Commission plans, groups, landing pages and MLM config are UI-only; CRM sync is outbound-only; no MCP server |
| `/sales-trackdesk` | Trackdesk — affiliate **network** software (multi-brand, multi-geography, two-sided advertiser+affiliate billing, offer caps, MLM tiers, iGaming NGR RevShare) positioned against PartnerStack/impact.com/Everflow/Affise rather than the Stripe-native indie cohort. **No free tier** despite roundups claiming one: Business $329/mo (revenue capped at $30k/mo), Enterprise from $499/mo ("Full API", white-label), Enterprise PLUS from $1,199/mo; self-serve with a 14-day trial, and **all fees non-refundable**. Unlike the sales-gated PRM tier its whole developer surface is public — a complete **OpenAPI 3.0 document** (`developers.trackdesk.com/api.instance.json`, a Scalar shell), **82 paths / 97 operations**, `X-Api-Key` auth on a **tenant subdomain** base URL, four distinct path families, and **`POST`-to-list** semantics where `POST /coupons/v1` creates but `/coupons/v1/list` reads. **Webhooks are completely unsigned** — no secret, no signature header anywhere in the spec — and **conversions carry no idempotency key**, so replayed billing webhooks double-pay; rate limits are undocumented and there is no sandbox. Its edge over the budget cohort: the **payout chain is API-drivable end to end** via Tipalti batches. Hosted MCP server (Search + Execute) for Claude/Cursor/Windsurf, though API and MCP plan-gating contradicts across the vendor's own pages |
| `/sales-linkjolt` | LinkJolt — zero-fee affiliate & referral software for **Stripe-native SaaS**, and the member of the indie Stripe-native cohort that owns two angles nothing else in the catalog covers. **First: Apple In-App Purchase attribution** — every other affiliate skill assumes a web checkout you control and a cookie you can set, while LinkJolt tracks **iOS subscription apps** via **App Store Server Notifications v2 + per-affiliate Subscription Offer Codes** (JWS verified against Apple Root CA - G3, recurring commissions chained through `originalTransactionId`, `REFUND`/`REFUND_REVERSED` handled) with **no SDK, no StoreKit changes and no mobile measurement partner** — which flips attribution from *click-shaped* to *code-redemption-shaped*: no cookie, no click id, and every affiliate needs an offer code minted in App Store Connect before they can drive one sale. **Second: 0% transaction fees with no pre-funded balance** — Stripe Connect payouts pull straight from your existing Stripe balance to 45+ countries, the direct counter to Rewardful's pre-funded model and to the ~3–5% cuts Tolt/Rewardful/FirstPromoter take. Ingests Stripe, Paddle, Lemon Squeezy, Gumroad, GoPay, WooCommerce and Apple IAP; dual link + coupon attribution; rule-based (**explicitly not AI**) fraud scoring; Discovery marketplace; and **Affiliate Teams** with per-member rate overrides, revenue targets and merchant-approved bonus pools. **Its defining trap is that the headline price is not the integration price** — the entry tier has **no API at all** (`401 plan_insufficient`), the next is **read-only**, and **writes and outbound webhooks both start two tiers up**, with Teams gated to the top plan. Above that the surface is deep: **36 REST endpoints**, **14 HMAC-SHA256-signed webhook events** (`X-LinkJolt-Signature: t=…,v1=…` over `` `${timestamp}.${rawBody}` ``, 5-minute replay window) and a **hosted MCP server** with spec-compliant OAuth (dynamic client registration + PKCE). Four traps verified by live probe: **every cURL example in the vendor's own docs silently drops your API key** (they target the apex, which `308`s to `www`, and clients strip `Authorization` cross-host — so it fails as `missing_api_key` and looks exactly like a bad key); **webhooks are delivered once with no automatic retry** and 5 consecutive failures pause the subscription, so a listener must be paired with a backfill; **the npm MCP package ships 7 of the 14 documented tools** (pinned at `0.1.0`, predating Teams/Coupons/Payouts); and **`plan_insufficient` arrives as both `401` and `403`**, so clients must branch on `error.code`. Payouts are **read-only** (no trigger endpoint), there is **no `Idempotency-Key` header** (natural keys only — treat `409 duplicate` as success), amounts write in major units but read back as strings, and **test keys skip webhook dispatch entirely** so a webhook integration cannot be rehearsed in test mode |
| `/sales-rekomi` | Rekomi — affiliate & referral software for SaaS and subscription brands, and the member of the Stripe-native cohort that puts **the whole back office inside the product**: it collects W-9 / W-8BEN / W-8BEN-E at onboarding and **gates payout eligibility on the form**, disburses via **Stripe Express and PayPal to 150+ countries**, and files **1099-NECs** at year end — closing both the payout gap PromoteKit leaves open and the tax-filing gap Refgrow leaves open. Self-serve at Starter $29 / Growth $49 / Pro $99 with a 14-day card-free trial, but **the subscription is not the cost line — a flat 3% fee applies to affiliate payouts**, so weigh it against real payout volume rather than plan prices. **61 REST endpoints** on `api.rekomi.com/api/v1` (Bearer `rk_live_`, read/read_write scopes), **19 HMAC-signed webhook events**, HMAC-signed S2S ingest covering anything outside the **11 native gateways** (Stripe, Paddle, Braintree, Shopify, Lemon Squeezy, Chargebee, Polar, Recurly, Gumroad, Creem, Dodo) including mobile IAP, 38 CRM/email connectors, Zapier, and a **hosted MCP server with 45 tools that works on every plan including Trial and bypasses tier gates the REST API enforces**. **Its defining limit: the payout run is not automatable** — `POST /payouts/run` and `/retry` return `403 interactive_session_required` to every API-key and OAuth caller, so design finance jobs as *prepare and alert* around the repeatable `payouts/preview` call. Live probing also found **no rate-limit headers at all** (429s arrive empty-bodied, so backoff must be blind), a **direction-dependent HMAC tag** (`v1=` outbound webhooks vs `sig=` inbound S2S, sharing a helper silently 401s), and that the vendor's canonical manifest at `/llms/api.txt` beats its own human docs where the two disagree |
| `/sales-endorsely` | Endorsely — affiliate-program software for subscription SaaS and the one member of the Stripe-native indie cohort that sells **recruiting rather than tracking**: the **AI Affiliate Finder** digests your site, infers your competitors, then scans the web, YouTube channels and newsletters for people already promoting them and returns ready-to-recruit prospects. **Free until $1,000/mo of affiliate-attributed revenue** (not company revenue — a $180k-ARR SaaS with a small program genuinely qualifies), then $39/mo to $5k/mo and $99/mo to $20k/mo, with Finder credits as the real tier gate. **Brand-bidding fraud detection free on every tier.** Its defining limitation: **the API is write-mostly and nothing reads back out** — two endpoints (`POST /refer` for conversions and free-signup leads, plus one promo-code lookup), no list endpoints, **no webhooks, no Zapier app** (both slugs 404 despite reviews claiming otherwise) and no MCP, so reporting and any migration off the platform are manual. `POST /refer` **accumulates with no idempotency key**, so a retry double-pays; a *wrong* API key returns plain-text `500` instead of the documented 401; the live rate limit is **10/min against a documented 100**. The tracker accepts **`utm_source`** as a referral code (an affiliate registering `newsletter` captures your own campaign traffic) and never overwrites an existing cookie, making attribution first-touch whatever the dashboard says. Multi-level commissions are marketed "coming soon" and not shipped; the Finder runs on YouTube API Services, whose terms govern what you may store |
| `/sales-affiliatebase` | AffiliateBase — affiliate-program software for **Stripe-billed SaaS** and the member of the Stripe-native indie cohort whose differentiator is the **automation surface itself**: the only one publishing a complete, downloadable **OpenAPI 3.1 contract** (`affiliatebase.io/openapi/v1.yaml`, 51 operations across 11 resource families) that you can read and generate a typed client from **without an account**, plus **svix-signed webhooks** (8 events) and a **hosted MCP server** (13 tools) — and it ships **REST API access on every tier including the $0 free plan**, where LeadDyno and PromoteKit gate it. Covers the `?via`-token-vs-generated-referral-ID trap that silently kills `client_reference_id` attribution, Stripe Payment Link / Buy Button / Pricing Table / custom Checkout Session wiring, svix HMAC verification (including two bugs in the vendor's own Node sample), the bare-object response on `GET /commissions/:id` that breaks generic `data`-unwrapping clients, payout runs whose `idempotency_key` is auto-generated when omitted, and the hard Stripe-only boundary (no `POST /commissions`, no manual-conversion escape hatch). Flags three contract defects: the sole published support address sits on a 1999-registered namesake domain with no MX records while the Terms make emailing it a precondition to any claim, the Terms say first-touch where the docs say last-click, and "fees are non-refundable" contradicts the advertised 30-day guarantee. |
| `/sales-kickofflabs` | KickoffLabs — viral marketing for pre-launch waitlists / bonus-entry giveaways / milestone rewards / leaderboard giveaways, REST API v1 + v2, server-side webhooks with `__fraudulent` flags (duplicate_ip / bounced / duplidate_email), AnyForm + KOL.js, native ESPs (Klaviyo/Mailchimp/ActiveCampaign/Brevo), Hobby $13/mo to Enterprise $202/mo annual |
| `/sales-upviral` | UpViral — viral referral marketing / list-building for sweepstakes, giveaways, pre-launch waiting lists, milestone referral programs; REST API (`app.upviral.com/api/v1/`, `uvapikey`+`uvmethod`) + Callback-URL webhooks gated to Business+, IP-based fraud detection, A/B testing, 30+ ESP/CRM integrations; Starter $79/mo (no API) to Premium $319/mo annual |

| `/sales-preshiplist` | Preshiplist — no-code pre-launch waitlist builder for SaaS/app makers that also **sends the launch emails itself** via built-in auto-branded drip sequences (confirmation/launch-day/updates); templates, custom domains, AI copy, portfolio metrics. The most closed member of the family — no API/webhooks/Zapier, CSV export is the only egress; free plan is draft-only (can't publish/collect); tiers Chill/Serious Builder + Lifetime, exact prices unpublished |

| `/sales-tuemilio` | Tuemilio — early-access waitlist + pre-launch validation with a viral referral loop, leaderboards, white-labeled dashboards, and a full developer trio (REST API `tuemilio.com/api/v1` `?api_token=` server-side, JS SDK for the browser, `new-subscriber`/`grant-access`/`confirmed-subscriber` webhooks); Zapier/Mailchimp/Typeform/GA; API+webhooks on all tiers, Founder $29 / Startup $49 / Enterprise |

| `/sales-sendowl` | SendOwl — digital-commerce + **secure-delivery** platform (downloads, software, ebooks, audio, video, courses): download-limit/expiry links, **PDF stamping**, **software license keys**, subscriptions, drip, bundles, upsells; **REST API** (Basic Auth, `api.sendowl.com`; orders on `/api/v1_3`, everything else `/api/v1`; ~1 req/sec) + **HMAC-signed webhooks** (`X-SENDOWL-HMAC-SHA256`, 14 order/subscription events, 10 retries); subscription pricing (Launch/Grow/Scale/Business) with annual **orders/year + sales/year caps**, **no free tier**, no per-transaction fee; hosts links not files; not a Merchant of Record |
| `/sales-printful` | Printful — print-on-demand (POD) merch fulfillment for creators/brands (apparel, accessories, all-over print, no inventory); store connectors (Shopify/WooCommerce/Etsy/Wix) + headless **REST API v2 beta + v1** (`api.printful.com/v2`, OAuth/Bearer, leaky-bucket 120 req/60s); mockup generator + 19 **signed** webhook events; order by `catalog_variant_id`, async cost calc before confirm; Free vs Growth ($24.99/mo, free above $12K/yr); community MCP server; not a Merchant of Record |

| `/sales-paddle` | Paddle — Merchant of Record billing for SaaS/apps (checkout, subscriptions, global sales-tax/VAT remittance, B2B invoicing, Retain, ProfitWell); Paddle Billing REST API (`api.paddle.com`, Bearer, sandbox) + HMAC-SHA256 webhooks + Docs MCP; Classic≠Billing; ~5%+$0.50 |
| `/sales-dodo-payments` | Dodo Payments — developer-first Merchant of Record for SaaS/AI/digital products: global tax/VAT/GST across 220+ countries, subscriptions + usage/credit billing, checkout, license keys. Full REST API (`test/live.dodopayments.com`, Bearer) for payments/subscriptions/products/customers/checkout/license-keys/refunds/payouts + Standard-Webhooks-signed events, 9 SDKs, framework adapters, CLI + MCP server; ~4% + $0.40/txn, no monthly fee |

REST API (`api.fastspring.com`, HTTP Basic, 250 calls/min) for products/orders/subscriptions/accounts/coupons/checkout + **HMAC-SHA256 webhooks** (`X-FS-Signature`, dedupe on event id); Classic API deprecated. **Quote-based** ~5.9%+$0.95 / 8.9% (effective ~10–12% on subs; refunds keep the fee) |
| `/sales-merchant-of-record` | Merchant of Record / payments-provider selection — MoR vs self-managed Stripe, and Paddle vs Lemon Squeezy vs FastSpring vs Dodo vs Polar vs Creem vs Gumroad on fees, tax coverage, B2B support, and switching cost |
| `/sales-subscription-billing` | Recurring-billing engine selection & operation — Chargebee vs Recurly vs Maxio vs Zuora vs Stripe Billing vs Orb vs Lago vs Zoho Billing; subscription-first vs usage-first, build-on-Stripe vs dedicated, open-source self-host (Lago), dunning/proration/revenue recognition (ASC 606); stay seller of record, keep tax in-house (NOT a Merchant of Record) |
| `/sales-truerev` | TrueRev — standalone ASC 606 revenue-recognition sub-ledger between a CRM and **QuickBooks Online**: contracts → contract products bound to QBO invoice lines → revenue schedules, deferred revenue and journal entries, plus scheduled invoices and SaaS metrics. Ships a customer-facing API (aggregators wrongly report "API: No") but publishes **zero** API docs, no webhooks, no Zapier app and no MCP server, behind a uniform 401 wall — so every integration polls. Signup is self-serve despite demo-only CTAs; the contract is annual, prepaid, non-refundable and auto-renewing with 30-day notice |
| `/sales-dualentry` | DualEntry — AI-native cloud ERP for mid-market finance teams (general ledger, AP/AR, bank match, fixed assets, multi-entity consolidation, subscription billing) with **ASC 606 revenue recognition as a first-class API resource**. Demo-gated with no self-serve signup and no published price, yet the **entire developer surface is public**: two OpenAPI 3.1 specs (228 V2 operations), a hosted MCP server with OAuth 2.1 dynamic client registration, and an open-source CLI. Sharp edges: auth failures return `403` not `401`, invoice writes are hard-capped at 2/minute, the spec ships empty `securitySchemes` and documents no `429`, there is no idempotency key on any write, and the webhook secret is a one-time reveal with no documented signature scheme |
| `/sales-campfire` | Campfire — AI-native cloud ERP for venture-funded startups and mid-market finance teams (general ledger, multi-entity + multi-currency consolidation, AP/AR, bank feeds and reconciliation, fixed assets, close management, financial statements) with **ASC 606 revenue recognition as its deepest module** — 86 of its 363 API operations, including product bundles with SSP allocations, milestones, usage revenue, prepaid commits with drawdown, and AI contract parsing. **Ember**, the in-product AI accounting agent, is UI-only. Pricing is permanently demo-gated (`/pricing` 404s and has *never* been archived), yet the **full OpenAPI 3.0.3 spec is served without authentication** and an `llms.txt` indexes every doc page. Sharp edges: trailing slashes are per-endpoint and asymmetric (a missing one returns `301`, which clients follow while downgrading `POST` to `GET` — a silent write no-op returning `200`; an extra one returns `404` with 73 KB of HTML), the spec marks `readOnly` fields as `required` in 42 of 113 request-body schemas so unmodified codegen cannot build a valid create, `Idempotency-Key` exists on exactly one endpoint (documented only in a leaked docstring), webhooks ship a `token` secret but **no documented signature scheme** and no topic enum, and the MCP server is **read-only (12 tools)** — not to be confused with the "MCP store", which points the opposite way and lets Ember call out to Ramp/HubSpot/Salesforce/Stripe |
| `/sales-rillet` | Rillet — AI-native cloud ERP and general ledger for B2B SaaS scaling beyond QuickBooks (automated GL, AP/AR, bank reconciliation, close management, multi-entity consolidation with FX revaluation, SaaS reporting) with **ASC 606 advanced revenue recognition** bundled in, including a **dry-run contract-amendment preview**. **Aura AI** (Chat, Embedded Agents, Flow) is UI-only. Pricing is demo-gated — `/pricing` **301s to `/demo`** — yet the **full OpenAPI 3.1 spec is served without authentication** (62 paths, **111 operations**, 224 schemas), alongside **23 declared webhooks**, an OAuth MCP server with **open dynamic client registration**, and — uniquely among the AI-native ERPs — a **sandbox environment**. The trap that inverts the verdict: `docs.rillet.com` is a private GitBook returning `401`, while the real portal is **`docs.api.rillet.com`**, named only in the site's `llms.txt`. Sharp edges: the no-header API-version default **changed from v1 to latest on 2026-08-01**, `PUT` is full-replace so omitted fields are nulled (and there is no `PATCH` except a usage upsert), the spec omits both `Idempotency-Key` and `429` even though a 24-hour idempotency key and a 60 req/min limit are real, cursors expire after 2 hours and **silently restart at page 1**, and the webhook HMAC key is the **base64-decoded** token over `$timestamp.$id.$entity.$event.$body` |
| `/sales-numeric` | Numeric — AI close-automation platform that sits **on top of** an existing general ledger (NetSuite, QuickBooks Online, Xero, Sage Intacct) rather than replacing it: close checklist, account reconciliation, flux analysis with AI-drafted commentary, ad-hoc financial reporting, transaction monitors and cash matching — the answer for teams who will not migrate their ERP. **There is no REST API and no OpenAPI spec; the MCP server at `api.numeric.io/mcp` is the entire public automation surface**, and it is fully scopable without an account via open OAuth discovery (dynamic client registration, device-code grant, S256 PKCE), a published capability matrix marking every capability ✅/⚠️/❌, and an MIT-licensed skills toolkit on GitHub. Sharp edges: `scopes_supported` holds only the four OIDC standards so there is **no read/write scope split** and least privilege means provisioning a restricted Numeric user; task **dependencies and attachments are unreachable**; **approval identity is non-delegable** (prepared/reviewed always records under the authenticated session user); **QuickBooks Online customers cannot drill into the GL lines behind a flux row**; warehouse connectors (BigQuery, Snowflake, Databricks, Workday WQL, NetSuite SuiteQL) point **inbound only**; and flux is Growth-tier while Cash Management is Enterprise, so plan gating shrinks the MCP surface itself. Essentials publishes a real price at $30/user/mo — the only member of this cohort that does |
| `/sales-nominal` | Nominal — agentic AI close-management and multi-entity consolidation layer that runs **on top of** an existing ERP (Workday, Microsoft Dynamics 365, Oracle, Sage Intacct, SAP, plus NetSuite/QuickBooks/Xero) rather than replacing the general ledger: Flux Analysis, Bank Reconciliation, Transaction Matching, Transaction Patrol and Trigger agents, close orchestration, intercompany consolidation, and a Shadow Ledger execution layer. Markets "0 ERP Changes Required"; SOC 1 certified. **Ships a live, spec-compliant MCP server at `api.nominal.so/mcp` that it has never documented anywhere** — no docs/developers subdomain, no OpenAPI spec, no API mention in its 201-URL sitemap, release notes or knowledge base, and zero web-search results — found only by probing `/.well-known/oauth-protected-resource/mcp`. The public OAuth metadata leaks the surface: a real **`nominal.read` / `nominal.write` scope split** (which Numeric lacks), **open dynamic client registration** so Claude Code and Cursor self-register, S256 PKCE, and `client_credentials`/CIBA for headless jobs — but **no device-code grant**. Sharp edges: the REST API is a **uniform 401 wall** (byte-identical for real and invented paths, so 401 is indistinguishable from 404); the **MCP tool list, rate limits and error envelopes are unknown, not absent**; no webhooks, no Zapier app, no documented warehouse export; write-back is self-contradictory ("bi-directional" Shadow Ledger vs agents working "outside the ERP — without changing your source data"); every agent output is a draft requiring explicit approval; and the Terms of Use governs the **website only**. **Pricing is fully demo-gated — the widely-cited "$499/month Pro Tier" and "30-day free trial" are fabricated** |
| `/sales-onestream` | OneStream — the unified enterprise EPM/CPM platform for the Office of the CFO (financial close, consolidation, FP&A, account reconciliation, transaction matching, tax provision, narrative reporting on one data model), and **the catalog's sharpest counter-example to the enterprise-cull heuristic**: every price signal says cull — `/pricing` 404s, no trial, no self-serve signup, Vendr-observed ~$178K/yr average with implementation often 2–4x license — yet **reachability inverts it**, because two complete 9.3.1 developer guides ship as public PDFs alongside a docs portal and a **1,177-page developer portal**, all with no account, no partner gate and no NDA. **The REST API is a narrow POST-only remote control, not a data API**: seven endpoints, zero GET/PUT/DELETE, that *run things you already built in the UI* (Data Management sequences, Dashboard Adapters, Cube Views) — there is no endpoint to create a sequence, adapter or any metadata, and no REST write-back into a cube. Sharp edges: `api-version` is a **query parameter, not a path segment**, and **newer is not better** — 7.2.0 adds async and a two-step SessionInfo chain but its DataProvider supports only `GetAdoDataSetForAdapter`, so upgrading *loses* Cube View, SQL and method-command reads; the **SI chain returns two different `XfBytes` values** and everything except `OpenApplication` needs the second; auth **forks on hosting with no shared code** (hosted cloud = personal access tokens, 365-day expiry, 100 per user, auto-revoking silently, requiring `AccessAsNonInteractiveUser` **which admin does not imply** and carrying **no scopes**; self-hosted = OAuth 2.0 via Entra ID/Okta/PingFederate; government tenants = asymmetric JWT); **zero hits for `webhook`, `rate limit`, `429` and `idempotenc`** across both guides, so a blind retry in front of `ExecuteSequence` starts a second consolidation; and the long-running-call fix (`XFCallState`) is **server-side config, not a client header**. Ships an **MCP-based Agentic Finance Layer** (Platform 9.3+) that names Claude, Copilot, ChatGPT and Gemini — **GA and marketed but publicly undocumented**, with no hostname or tool list anywhere, so it is tenant-provisioned. The deep programmability is **in-platform .NET Business Rules** (VB.NET/C#, `BRApi`), not REST |
| `/sales-planful` | Planful (formerly **Host Analytics**) — enterprise FP&A/EPM. **One brand, two products, and only one has an API**: the finance platform (Structured Planning, Dynamic Planning, Consolidation, Reporting, plus Predict ML forecasting as a separate SKU) ships a **47-endpoint public REST API**, while **Planful for Marketing** — the Plannuh product acquired in 2022 — does marketing budget and campaign spend management with **no public API at all**. The API docs are a JS-rendered **Postman Hosted Site**; the full collection JSON is served from Planful's own domain and readable with no account, which is why this is a build despite pricing being entirely demo-gated — **reachability decides, not price**. Sharp edges: **two auth schemes split by path prefix** (`/financemodel/*` and `/api/admin/*` take Basic AccessId/AccessKey, `/modeling/*` requires a non-expiring `X-Access-Token` header) — the usual cause of "my key works on some endpoints but not others"; a **40 MB request cap** returning 413 with an end-of-load signal sent as an HTTP **header**, not a body field; **"webhooks" are one-shot per-request callbacks, not subscriptions**; **no MCP server**; **zero rate-limit or 429 documentation**; a 401 returns **plain text** while a 404 returns JSON, so `response.json()` raises on the auth error itself; and Planful's own published examples ship invalid JSON and an `ExcecutionId` typo |
| `/sales-vena` | Vena Solutions — the Microsoft/Excel-native FP&A and operational planning platform, and the deliberate **inverse of every "escape your spreadsheet" vendor**: finance stays *in* Excel while Vena supplies the governed OLAP cube (**CubeFLEX**), workflow and audit trail behind the workbook. **Every planning module is UI-only** — budgeting, close, consolidation, reconciliation, workforce/CapEx planning, Sales Performance Management, Incentive Compensation and Marketing Planning — and the public API is a narrow **13-endpoint data pipe** across the boundary of the cube (11 ETL/import + `getIntersections`/`getHierarchy` export, HTTP Basic `apiUser`/`apiKey`). A build despite fully demo-gated pricing, because **reachability decides**: docs are open and Vena embeds a one-path OpenAPI fragment on every reference page. Sharp edges: a **uniform 401 wall with an empty body** (identical for real and invented paths, so 401 proves nothing); the **documented hub enum is incomplete** — `us5`, `us6`, `ca1` and `eu3` are live undocumented regions, so validating against the spec rejects real tenants, and a wrong hub fails at **DNS**, not HTTP; **zero webhooks anywhere**, so polling job status is the only completion signal; **no idempotency key on any endpoint**; **two separate import caps** (25 MB *and* 10,000 rows); and three `filters` traps, two of them **silent** — a parent-member filter returns empty data with a 200, and a capitalized `FILTERS` is ignored and returns everything. Ships a real **read-only MCP server** (4 tools, Claude/ChatGPT/Copilot/Perplexity setup) that **does not work when Force SSO is enabled**, and a Power Automate connector with **5 actions, zero triggers** that exposes MQL and LID/attribute export the REST API lacks |
| `/sales-marketing-budget` | Marketing budget and spend management — tool-agnostic. Covers the five-level hierarchy (budget → segment → goal → **campaign, which carries metrics, or expense group, which does not** → expense), the **Planned/Committed/Closed** expense lifecycle, and funnel metrics (CPO, ROI, **ARPO**). The two failures it exists to prevent: **skipping the Committed state**, which is the single most common cause of apparent overspend because a cost is real at contract or PO signature long before an invoice exists; and confusing **cost per outcome with ROI**, which needs a revenue-per-outcome figure most teams never supply. Platform selection across Planful for Marketing, Allocadia, Uptempo and Hive9 — a category that is uniformly enterprise-priced, demo-gated and API-poor, with **inbound read-only connectors** and no scheduled export — so for most teams the honest answer is a structured spreadsheet, and the real buying triggers are invoice ingestion, scheduled ad-spend pulls and approval chains rather than reporting |
| `/sales-chargebee` | Chargebee — subscription-billing & revenue-management engine on your own gateway (NOT a Merchant of Record); REST API v2 (`{site}.chargebee.com/api/v2`, HTTP Basic key-as-username/empty password, form-encoded, offset pagination, idempotency header) + webhooks with **no HMAC** (basic-auth/secret-URL/IP-allowlist, dedupe on event id, order by resource_version) + AgentKit MCP server; Product Catalog 1.0↔2.0 split, Smart Retry dunning, proration, RevRec/Retention add-ons; free Starter cumulative $250K cap → 0.75% overage |
| `/sales-churn-reduction` | Subscription churn reduction strategy — voluntary churn (cancel flows, exit surveys, save-offer ladder led by pause not discount) vs involuntary churn (dunning, decline-type-aware retries, card updater); vendor selection across Churnkey, ProsperStack, Chargebee Retention (Brightback), Churn Buster, Upzelo, Raaft, Paddle Retain, Baremetrics Recover; build-vs-buy, honest save-rate measurement, click-to-cancel compliance |
| `/sales-churnkey` | Churnkey — retention layer on top of Stripe/Chargebee/Paddle/Braintree/Maxio: in-app cancel flows with pause/discount/plan-change/trial-extension offers + Precision Retries and dunning campaigns; Data API (`api.churnkey.co/v1`, dual-header auth, offset pagination), HMAC `ck-signature` webhooks (`session`/`dunning`), and an MIT MCP server (~54 tools, OAuth 2.1 PKCE, 23 scopes) that is the **only** surface able to edit flow configuration; free Churn Metrics dashboard, webhooks gated to Core tier |
| `/sales-revenudge` | Revenudge — the churn-reduction price floor: Stripe-only **pre-dunning** that emails a branded card-update prompt before the renewal charge fails, plus branded recovery sequences replacing Stripe's defaults, recovery analytics, A/B-tested subject lines and Slack alerts; priced on **tracked MRR** (not seats or volume) so the self-serve ceiling is the mid tier, with no API, webhooks, MCP server or Zapier app — the "API access" bullet sits only on the Contact-sales tier |
| `/sales-membervault` | MemberVault — "binge & buy" course/membership marketplace, gamification (Engagement Points), warm/hot lead tagging, 0% fees; no REST API — Zapier (Hot Lead trigger) + inbound/outbound webhooks; bring your own ESP |
| `/sales-graphy` | Graphy (formerly Spayee) — all-in-one courses, memberships, communities, coaching, webinars + no-code branded mobile apps; REST API on top plan (MID + key) + 9 webhook triggers (auto-disable after 5 failures), Zapier/Pabbly |
| `/sales-memberful` | Memberful — membership + paid-subscription layer (Patreon-owned) for creators/publishers/communities: gated content, private podcasts, newsletters, downloads, OAuth SSO, all on your own Stripe. GraphQL API (`ACCOUNT.memberful.com/api/graphql`, Bearer key, cursor pagination; members/subscriptions/passes/plans/coupons) + 21 HMAC-SHA256-signed webhooks (`X-Memberful-Webhook-Signature`); WordPress/Discord/Mailchimp/Kit. Free 10% / Pro $25 4.9% fees |
| `/sales-memberstack` | Memberstack — no-code membership, auth (login/2FA/social), and Stripe payments + content gating for Webflow/WordPress/custom sites; Admin REST API (`admin.memberstack.com`, X-API-KEY, member CRUD, verify-token, 25 req/s) + 8 webhooks + DOM package |
| `/sales-groupapp` | GroupApp — learning-focused community platform: communities + deep LMS (curriculum builder, branded certificates), events, B2B group subscriptions, 0% fees; API token + webhooks + OAuth + Zapier (11 triggers/10 actions) |
| `/sales-ruzuku` | Ruzuku — simple teaching-first course/membership platform (drag-and-drop builder, drip, live/cohort courses via Zoom, certificates), direct Stripe/PayPal at 0% fees; no public REST API — Zapier only (7 triggers/3 actions; certificates/white-label/storefront gated to Pro) |
| `/sales-xperiencify` | Xperiencify — gamified course platform built to drive completion (Experience Engine: XP/XXP points, badges, leaderboards, variable rewards, countdowns); REST API (`api.xperiencify.io`, `?api_key=`, ~18 endpoints incl. redeem/unredeem points) + Zapier (4 triggers/8 actions) + webhook export; billed by active monthly students; affiliate tracking but no payout dashboard |
| `/sales-zenler` | New Zenler — live-session-first all-in-one course/membership platform (built-in interactive webinars/live classes, funnels, email, 0% fees, multi-instructor); REST API (`api.newzenler.com/api/v1`, `X-API-Key` + `X-Account-Name` headers, ~25 endpoints, 1000/min) + Zapier (7 triggers/7 actions) + Make; no native webhooks; API/memberships/affiliate/white-label are Pro-gated |
| `/sales-freshlearn` | FreshLearn — budget all-in-one LMS/creator platform (unlimited learners, 0% fees, deep AI Studio for course creation/chat-with-content/coaching); REST API (`api.freshlearn.com/v1`, `api-key` header, cursor pagination) + native webhooks + Zapier (6 triggers/9 actions, enroll upserts); API/workflows gated to No Brainer+, Zapier/community to No Brainer |
| `/sales-teachery` | Teachery — minimalist, design-first course builder (flat-rate, 0% fees, unlimited courses/students, custom-CSS Payment Pages); no public REST API — Zapier (3 triggers/4 actions: enroll/revoke Course or Theme) + Make/Pabbly; no native video hosting (embed-only), no quizzes/multi-instructor; built-in course affiliate feature |
| `/sales-membership` | Membership sites and online courses — structure, pricing, retention |
| `/sales-thrivecart` | ThriveCart — lifetime-license checkout/cart for creators (order bumps, 1-click upsells/downsells, A/B testing, dunning, Affiliate Center); event-driven webhooks + Event Subscription API + REST (token/OAuth, 60/min, PHP SDK), secret-validated (no HMAC); Pro+ $295/yr gating; Learn deprecated; no download protection |
| `/sales-samcart` | SamCart — **subscription-priced checkout/cart** for digital-product creators (conversion templates, order bumps + 1-click upsells, checkout A/B testing, **Subscription Saver dunning**, Affiliate Center, AI page/copy generation); **read-mostly REST API v1** (`api.samcart.com/v1`, **`sc-api` key header — private beta, key via support**, official OpenAPI spec; `next`/`prev` pagination, cents money values; refund charge, cancel/`scheduleCancel` subscriptions) + **Notify URL webhooks** (~15 triggers via Integration Engine rules — **unsigned, no documented retries**: tokenize endpoint + verify via API + polling backup); Core $79/mo vs Pro $199/mo (**bumps/upsells/A-B/affiliates Pro-gated**); recurring payments don't port off; not a Merchant of Record |
| `/sales-checkoutpage` | Checkout Page — **no-code Stripe-based hosted checkout builder** for digital products, subscriptions, payment plans, pay-what-you-want, and **event tickets**, plus form/lead capture; order bumps, 1-click upsells, cart-abandonment recovery; **0% platform fees** with **sales-volume-cap pricing** (Launch/Grow/Enterprise, ~99% of features shared); **NOT a Merchant of Record** (own Stripe → own tax). REST API (`api.checkoutpage.com/v1`, Bearer, cursor pagination, 500/min store + 100/min key) + a single **`conversion` webhook** (`object: payment/subscription/submission`, **decimal-string money not cents**, **unsigned — no HMAC**: tokenize URL + re-fetch to verify, dedupe on `orderId`) + a **native MCP server** (`mcp.checkoutpage.com`, OAuth, 13 tools) so an assistant can build a paid checkout from a prompt; Stripe-only |
| `/sales-ecwid` | Ecwid (by Lightspeed) — **embeddable ecommerce**: add a store/checkout to any existing site (WordPress/Wix/custom) + hosted Instant Site; 0% platform fees, multichannel (IG/TikTok/Google/Amazon); **REST v3** (`app.ecwid.com/api/v3/{storeId}`, Bearer `secret_*`/`public_*` tokens, 600 req/min + `Retry-After`, **API paid-plan-only**) + **HMAC-signed webhooks** (`X-Ecwid-Webhook-Signature`; signing key is the app **client_secret, not the secret_ token** — the classic footgun; thin payloads → re-fetch); plan gates: digital goods Venture+, variations Business+; QuickBooks sync one-way; not a Merchant of Record |
| `/sales-snipcart` | Snipcart — **developer-first embeddable cart** for static/JAMstack sites (Hugo/Gatsby/Next/Astro/WordPress): products as `data-item-*` attributes, **prices validated by crawling your product URLs** (`product-crawling-failed` on JS-rendered pages → JSON crawling endpoint); **REST API** (`app.snipcart.com/api`, Basic auth — **key as username**), webhooks via **token-callback verification** (`X-Snipcart-RequestToken` → `/api/requestvalidation/{token}`, no HMAC/retries), JS SDK, **official hosted MCP server** (~38 tools, `X-Snipcart-Api-Key`) for Claude Code/Cursor; pricing max(~$20/mo, 2% of sales); not a Merchant of Record |
