Embed Cal.com booking widgets in WordPress via a Gutenberg block, Elementor widget, or [bookit] shortcode.

== Description ==

**BookIt for Cal.com** is the easiest way to add Cal.com scheduling to your WordPress site. It provides three integration methods so you can use whichever fits your workflow:

* **Gutenberg block** — drag the *Cal.com Booking* block into any page or post.
* **Elementor widget** — find the *Cal.com Booking* widget in the *BookIt* widget panel.
* **Shortcode** — paste `[bookit event="username/slug"]` anywhere.

= Features =

* Three display modes: **popup button**, **popup text link**, and **inline calendar**.
* Full **theme support**: light, dark, or auto (follows the visitor's OS preference).
* Custom **accent color** per widget or globally.
* **Smart loading** — the Cal.com embed script is loaded only on pages that actually contain a booking widget, keeping all other pages fast.
* **Pre-fill** logged-in user name and email automatically.
* **Cal.com API integration** — connect your API key to pick event types from a dropdown instead of typing slugs manually. Results are cached for 1 hour.
* "Refresh event types" button in the admin with one click.
* Compatible with Elementor **Free** and **Pro**.
* Full **i18n** support — ships with a French (fr_FR) translation.

= External services =

This plugin connects to external services operated by Cal.com, Inc.:

* **Cal.com API** (`https://api.cal.com` or `https://api.cal.eu` for the EU region) — used to fetch your event types when an API key is configured. Only called from the WordPress admin when you save settings or click "Refresh event types".
* **Cal.com embed script** (`https://app.cal.com/embed/embed.js` or `https://app.cal.eu/embed/embed.js` for the EU region) — loaded on the frontend to render booking widgets. Loaded only on pages that contain a booking widget (smart strategy) or on all pages (always strategy), depending on your settings.

The API base URL is configurable in Settings → BookIt. The default is the global Cal.com instance (`api.cal.com` / `app.cal.com`). Users on the Cal.com EU instance should set it to `https://api.cal.eu`.

By using this plugin you agree to Cal.com's [Terms of Service](https://cal.com/terms) and [Privacy Policy](https://cal.com/privacy).

== Installation ==

1. Upload the `bookit-for-calcom` folder to `/wp-content/plugins/`.
2. Activate the plugin through the **Plugins** screen in WordPress.
3. Go to **Settings → BookIt** to configure your Cal.com API key and default options.
4. Add a booking widget using the Gutenberg block, Elementor widget, or `[bookit]` shortcode.

== Frequently Asked Questions ==

= Do I need a Cal.com account? =

Yes. You need a free or paid Cal.com account to get an event slug. An API key is optional but enables the event type dropdown in the editor.

= Where do I find my API key? =

In Cal.com: **Settings → Developer → API Keys**.

= What is the event slug format? =

`username/event-slug` — for example `jane/consultation-30min`.

= Does this work with Elementor Free? =

Yes. All core features work with Elementor Free. Typography controls require Elementor Pro.

= Is the Cal.com embed script loaded on every page? =

By default, the **Smart** loading strategy loads the script only on pages that contain a `[bookit]` shortcode, a *Cal.com Booking* Gutenberg block, or an Elementor BookIt widget. Switch to **Always** in settings if you prefer unconditional loading.

= Can I pre-fill the booking form with the logged-in user's details? =

Yes. Enable the "Pre-fill logged-in user data" option per block/widget/shortcode. The visitor's display name and email will be sent to Cal.com.

== Changelog ==

= 1.0.3 =
* Fix: Elementor widget showing 404 in Cal.com popup — event slug now correctly prefixed with username (Cal.com v2 API nests username under owner/profile/user, not at root level). Added username-resolution fallback in render() for slugs saved without prefix.

= 1.0.2 =
* Fix: Shortcode Helper event dropdown not populated on fresh installs — auto-fetches event types via AJAX if the cache is cold.

= 1.0.1 =
* Fix: admin JS not loaded on settings page — "Refresh event types" button was unresponsive.

= 1.0.0 =
* Initial release.

== Upgrade Notice ==
