如何通过wordpress api请求从对象发送的响应中获得响应

Question

I have registered a api request the following way in the code, then in postman I call that request and add some params, but when I run the api request endpoint it returns null. How do I return the data that's being sent?

/**
 * This is our callback
 * function that embeds our phrase in a WP_REST_Response 
 */

function addProductFromCRM($data) {

  //$name = $data['name'];
  // rest_ensure_response() wraps the data we want to return into a WP_REST_Response, and ensures it will be properly returned.
  return rest_ensure_response($data);
}

/**
 * This function is where we register our routes for our example endpoint.
 */
function wp_register_crm_routes() {

  // register_rest_route() handles more arguments but we are going to stick to the basics for now.
  register_rest_route('crm/v1', '/addproduct/', array(
    // By using this constant we ensure that when the WP_REST_Server changes our readable endpoints will work as intended.
    'methods' => 'POST',
    // Here we register our callback. The callback is fired when this endpoint is matched by the WP_REST_Server class.
    'callback' => 'addProductFromCRM',
  ));
}

add_action('rest_api_init', 'wp_register_crm_routes');

What addproduct endpoint should return? JSON? You can do something like this:

function addProductFromCRM($request) {
    wp_send_json($request->get_params());
}
