Our Apple Pay merchant domain verification appears to have expired or been revoked without any notification.
We discovered the issue only after Apple Pay on the Web stopped working and we saw errors during the merchant session call.
Is there a way to determine:
When the merchant domain verification became invalid?
What event caused it to expire or be revoked?
Whether Apple provides notifications when the verification status changes?
Whether there is an API or recommended monitoring method to proactively check merchant domain verification status?
We would like to understand how this is controlled so we can detect the issue before it impacts Apple Pay on the Web.
