Easily integrate the eTermin.net online appointment scheduling calendar into your WordPress website via Shortcode.

== Description ==

This plugin allows you to embed the **eTermin.net** online booking calendar directly into your WordPress pages or posts. It provides a simple settings page to store your WebID and a flexible shortcode for placement.

It automatically handles the integration via iFrame and includes the necessary scripts to adjust the height of the calendar dynamically.

== External Services ==

This plugin relies on the 3rd party service **eTermin.net** to function. It uses this service in two ways:

1.  **Booking Calendar (iFrame):** It embeds the calendar interface via an iFrame directly from `https://www.eTermin.net`.
2.  **Resizing Script:** It loads an external JavaScript file (`resizecustomersitescroll.min.js`) directly from `https://www.eTermin.net` to handle the automatic height adjustment of the calendar.

**Data Privacy Description**
When the calendar is loaded (via the Shortcode), the user's IP address and browser information (User Agent) are sent to `https://www.eTermin.net` to retrieve the calendar content and the Javascript file. This is required for the technical functionality of the service.

**Service Provider**
This service is provided by eTermin GmbH.

== Installation ==

1.  Upload the plugin files to the `/wp-content/plugins/etermin-booking` directory, or install the plugin through the WordPress plugins screen.
2.  Activate the plugin through the 'Plugins' screen in WordPress.
3.  Go to the new menu item **eTermin** in your dashboard side menu.
4.  Enter your eTermin **WebID** (the suffix of your booking URL) and save changes.
5.  Use the shortcode `[etermin]` on any page or post to display the calendar.

== Frequently Asked Questions ==

= Do I need an eTermin account? =
Yes, you need an active account at eTermin.net to use this plugin. The plugin visualizes your existing calendar.

= Where do I find my WebID? =
Login to your eTermin dashboard. Look at the URL of your booking page (e.g., `https://www.etermin.net/my-practice`). The part after the slash (`my-practice`) is your WebID.

= Can I change the size of the calendar? =
Yes. The default height is 1600px, but it will try to auto-resize using the external script. You can force a starting height via shortcode: `[etermin height="1000px"]`.
