How server responds to device for GET request for updating a pass

Question

For getting the Latest Version of a Pass, GET request to webServiceURL/version/passes/passTypeIdentifier/serialNumber. What server do to respond to this request ? This is code I use:
if (strtoupper($_SERVER['REQUEST_METHOD']) === "GET" && $request[3]==='passes'){ $passTypeID = $request[4]; $serial = $request[5]; $auth_key = str_replace('ApplePass ', '', $headers['Authorization']); }

Answer 1

From the Apple Docs.

• If request is authorized, return HTTP status 200 with a payload of the pass data.
• If the request is not authorized, return HTTP status 401.
• Otherwise, return the appropriate standard HTTP status.

The "payload of the pass data" means the .pkpass bundle.
