Webhooks.

the event data is being sent in the POST request body. In PHP we can access this information like so:

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

once you have run that snippet of code, your event can be found in $event_json.

As the browser never navigates to these PHP files, it is a good idea to write all your output to files

For example, My "create.php" file looks like this:

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

ob_flush();
ob_start();

  var_dump($event_json);

file_put_contents("post.txt", ob_get_flush());

hat you get in the signature is just there to let you verify the POST response body hasn't been tampered with/intercepted. I don't know anything about HMAC-MD5 so I'm not going to try and explain it here :P

I hope this has helped you guys :)

lastly... Patreon!! can we please see this^^^ in the Documentation!? haha (this is 4 hours of my life I'm not getting back)

I believe you now have the basic information you need to understand how this works :)

Regarding this, I've tried doing this myself and in my file, all it says is NULL. I'm still confused on how I'm supposed to obtain the webhook information.

[Linkupdated]

$patreonEvent = $_SERVER['HTTP_X_PATREON_EVENT'];
$patreonSignature = $_SERVER['HTTP_X_PATREON_SIGNATURE'];

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

file_put_contents("post.txt", json_encode($event_json, JSON_PRETTY_PRINT));

Here's my code for testing if it helps anyone. Still looking into how to validate with the HMAC-MD5
