  ));
});

// Webhook Handler Functions
function handle_task_completed_webhook($request) {
  $data = $request->get_json_params();
  // Forward to n8n or process data
  $n8n_url = get_option('n8n_task_completed_url', '');
  if (!empty($n8n_url)) {
    wp_remote_post($n8n_url, array(
      'body' => json_encode($data),
      'headers' => array('Content-Type' => 'application/json')
    ));
  }
  return new WP_REST_Response(array('success' => true), 200);
}

function handle_journal_saved_webhook($request) {
  $data = $request->get_json_params();
  $n8n_url = get_option('n8n_journal_saved_url', '');
  if (!empty($n8n_url)) {

  if (!empty($n8n_url)) {
    wp_remote_post($n8n_url, array(
      'body' => json_encode($data),
