External Services

This plugin connects to external services only when an administrator manually clicks the “Run Test Requests” button in the Settings tab. This feature is designed to verify that the HTTP request tracking functionality is working correctly.

When the test is run, the plugin sends simple GET requests to:

1. httpbin.org – A testing service used to verify HTTP request tracking.

   • Data sent: A simple GET request with no user data
   • When: Only when admin clicks “Run Test Requests”
   • Terms of Service | Privacy Policy

2. api.wordpress.org – The official WordPress.org API, used to test JSON API response tracking.

   • Data sent: A simple GET request to the version-check endpoint (no user data)
   • When: Only when admin clicks “Run Test Requests”
   • Terms of Service | Privacy Policy

3. jsonplaceholder.typicode.com – A free testing API used to verify HTTP tracking with JSON responses.

   • Data sent: A simple GET request with no user data
   • When: Only when admin clicks “Run Test Requests”
   • Terms of Service | Privacy Policy

Important: These external requests are never made automatically. They only occur when an administrator explicitly initiates the test feature. No user data, site data, or any personal information is transmitted to these services.
