AI-powered product recommendations for WooCommerce — bestsellers, cross-sell, upsell, and similar products.

== Description ==

Nudgio Technologies connects your WooCommerce store to the Nudgio recommendation engine to display personalized product recommendations on your storefront.

**Features:**

* Bestseller recommendations based on real order data
* Cross-sell recommendations ("frequently bought together")
* Upsell recommendations (higher-priced alternatives)
* Similar product recommendations
* Simple `[nudgio]` shortcode with customizable attributes
* Gutenberg block with 35 visual settings in 8 organized groups — no shortcodes needed
* Auto-detects WooCommerce product ID on product pages
* HMAC-signed URLs — your API secret never appears in page source
* Full visual customization: widget container, title, layout, card, image, product title, price, and CTA button
* Iframe-based rendering — no CSS conflicts with your theme
* Auto-resizing iframes — content height adjusts automatically

**Requirements:**

* A Nudgio account with an active connection ([nudgio.tech](https://www.nudgio.tech))
* An API key generated from your Nudgio dashboard (Connection → API Keys tab)
* WooCommerce 7.0 or later
* PHP 8.0 or later

**Third-Party Service:**

This plugin connects to the Nudgio recommendation engine ([nudgio.tech](https://www.nudgio.tech)) to generate and display product recommendations. When a page containing a Nudgio shortcode or block is loaded, the plugin sends an HMAC-signed request to the Nudgio server with the Key ID, widget configuration parameters, and product ID (if applicable). No personal visitor data is collected or transmitted.

== Frequently Asked Questions ==

= How do I get an API key? =
