How to extend woocommerce api endpoints?

To extend WooCommerce API endpoints, you can use the WordPress hooks and filters provided by WooCommerce. WooCommerce provides a range of hooks and filters to allow developers to add custom functionality to their store.

Here are the steps to extend WooCommerce API endpoints:

1. Create a custom plugin or add the code to your theme's function.php file.
2. Use the WooCommerce hooks and filters to add custom endpoints to the API.
3. You can use the register_rest_route function to register a new endpoint. For example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12

add_action( 'rest_api_init', 'custom_endpoints' );

function custom_endpoints() {
    register_rest_route( 'myapi/v1', '/custom-endpoint', array(
        'methods' => 'GET',
        'callback' => 'custom_endpoint_callback',
    ) );
}

function custom_endpoint_callback( $request ) {
    // Your custom endpoint logic goes here
}

1. You can also use the woocommerce_rest_{post_type}_object_query filter to modify the query parameters for a specific endpoint. For example:

1
2
3
4
5
6
7

add_filter( 'woocommerce_rest_product_object_query', 'filter_product_objects_query', 10, 2 );

function filter_product_objects_query( $args, $request ) {
    // Modify the query parameters here

    return $args;
}

1. Once you have added your custom endpoints and logic, you can now use these endpoints to interact with your WooCommerce store via the API.

By following these steps, you can extend WooCommerce API endpoints to add custom functionality to your store.
