I'm having trouble getting stripe webhooks to work, this is my code:

            require_once('/var/www/html/application/views/config.php');

            \Stripe\Stripe::setApiKey("sk_test_***********");

            $input = @file_get_contents("php://input");
            $event_json = json_decode($input);

            //$event = \Stripe\Event::retrieve($event_json->id);

I've verified that $input is receiving the json data, but the $event_json variable is always empty.

I'm really confused by this, it seems like the json_decode is not working even though $input contains the correct data.

Can anyone shed some light on this?

Thanks in advance!
