Message Issue

[teamcoltra]

It seems like messaging is giving a 404 error for me (not 500), and I already validated the person's user by doing $tinder->user('THEIR ID'); and that worked fine, but if I use sendMessage:

stdClass Object
(
    [status] => 404
    [error] => 
)

Here is my code incase I am being dumb (trust that the key works because it is)?

require('vendor/autoload.php');
$tinder = new \Pecee\Http\Service\Tinder('###', '###');

print_r($tinder->sendMessage('####', '¡Hola, Mackenzie! Happy Thursday! Glad we matched, stupid question time: If you were a vegetable, what vegetable would you be?'));
