Creating custom REST API endpoints enhances WordPress’ integration with external apps. Using register_rest_route
in functions.php
, developers can define custom endpoints and callback functions to handle requests, extending REST API to meet complex data requirements.
add_action('rest_api_init', function() {
register_rest_route('myplugin/v1', '/data/', array(
'methods' => 'GET',
'callback' => 'my_custom_function',
));
});
