Upcoming changes to the App Store receipt signing certificate
December 20, 2022
Starting January 18, 2023, the App Store receipt signing certificate will use a new WWDR intermediate certificate. The existing intermediate certificate expires on February 7, 2023. In most cases, this certificate change won’t require changes to apps. However, we recommend reviewing how you verify the sale of your apps and in-app purchases from the App Store to make sure your apps aren’t impacted.
If you validate App Store receipts on device using the App Store receipt signing certificate, make sure you haven’t hardcoded the intermediate certificate and verify that the chain of trust for the container’s signature matches the Apple Inc. Root Certificate.
