Now that you’ve explored basic API interactions, let’s dive deeper into advanced API functions, custom endpoints, and more complex integrations. These advanced techniques will allow you to extend MemberPress functionality, integrate with third-party systems, and handle complex workflows with precision.

If you want to extend MemberPress and create custom API endpoints for your membership site, you can leverage WordPress hooks and the WordPress REST API to expose additional functionality. This is especially useful if you need to handle custom membership logic that isn’t covered by the default MemberPress API.

Example: Create a Custom Endpoint to Fetch Premium Content Access Stats

Let’s say you want to create a custom API endpoint that retrieves how many times premium content has been accessed by each member.

Steps:

1. Create a Custom Plugin:
   • To create custom API endpoints, it’s best to write the code in a custom WordPress plugin. Here’s the basic structure of a plugin:
   <?php /* Plugin Name: Custom MemberPress API Description: Extending MemberPress API with custom endpoints. */ add_action('rest_api_init', function() { register_rest_route('custom_mp/v1', '/content-access-stats', array( 'methods' => 'GET', 'callback' => 'get_premium_content_stats', 'permission_callback' => '__return_true', // Set permission rules here )); }); function get_premium_content_stats() { // Custom logic to retrieve content access data from the database $content_stats = array(); // Assume this holds your data return new WP_REST_Response($content_stats, 200); }
   • This code registers a new custom API route under /wp-json/custom_mp/v1/content-access-stats.
2. Call Your Custom API:
   • You can now call this custom endpoint from Postman, cURL, or any third-party application: GET https://your-site.com/wp-json/custom_mp/v1/content-access-stats
