提交重力表单后，mycred减去不起作用

Question

我正在尝试在提交重力表格后减去mycred点，但是它不起作用，下面我指定了我的整个功能，非常感谢您提供任何帮助，谢谢

add_action("gform_after_submission_1", "send_messagge", 10, 2);
function send_messagge($entry, $form) {
//$mycred  = mycred();
//$balance = $mycred->get_users_balance( get_current_user_id() );
$user_id = get_current_user_id();
mycred_subtract('Certificate Generation', $user_id, $balance, 'Credits Claimed');
$response = wp_remote_post(
    'https://api.textlocal.in/send/? 
    apikey=V9YcUuFH/wg-6TVbDCVtNPZnaNfoxqly54A9BhCpY4&sender=SIOIND', 
    array (
        'method'=> 'POST',
        'headers'=> array(),
        'body' => array ('numbers'=>919741791445, 'message'=> 'Dear aejaz from '.$user_id.', your registration number for sio conference is '.$balance.' . Remember to show this number on registration counter.' )
    )
);
}
