How often may my server query https://buy.itunes.apple.com/verifyReceipt in order to verify the status of an auto-renewable subscription?
To ask this another way, does this "verifyReceipt" endpoint have a connection limit (either per minute, per hour, or per day) that my server must respect?
(I could find no mention of query limits in https://developer.apple.com/library/mac/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html)
Thanks!
