We have implemented the register for push endpoint, but sometimes the endpoint is called with exactly the same arguments over and over up to a couple of thousand times. The first call returns 201 and the rest returns 200 just like the [documentation][1] specifies.

Is there anything other than the http status code that could cause it to retry like this? [1]: https://developer.apple.com/documentation/walletpasses/register_a_pass_for_update_notifications
