Hi, I've been trying to look in the documentation and REST API reference and I haven't found any mention about having a rate limit. Is there any rate limit on sending messages for Apple Messages for Business? Is there any rate limit on receiving webhooks for Apple Messages for Business? Thanks

I'm trying to initiate an Apple payment request and I successfully get a payment session and get a 200 status code when I send the payment message it self. But on my iPhone I always receive "Invalid Payment Request". even though everything else seems to work fine. Any ideas what the issue could be?
