We get the user cancels in the next 30 days from our database and we call to Apple one to one
https://buy.itunes.apple.com/verifyReceipt
We want to call for a list of user cancels in the next 365 days which can be a huge list.
I look for that in the documentation and in google but I couldn't find if there is a limit on the number of requests to Apple.
Does anyone know that?
After contact Apple's support, there are not query limits.
I have this endpoint implemented several months ago and I make a huge number of requests every day without any problem.
It's the only way to verify the status of each receipt because their webhook doesn't seem reliable.
