I've encountered an issue where we need multiple domain associations with separate Apple Pay implementations.

Briefly, we have a /.well-known/apple-developer-merchantid-domain-association already setup with Stripe, and now we need another, different version of the file to get setup with FreedomPay. FreedomPay insists this file represents a three-way relationship between all parties and I have no reason to disbelieve them.

I'm wondering if anyone has encountered this or if there is a standard procedure. I'm currently trying to find documentation on the exact way Apple Pay verification interacts with this file to see if we can produce it dynamically.

Hi @Hunt_Welch,

The Apple Pay Web Merchant Registration API is intended for payment platforms and e-commerce providers, to register and manage a portfolio of merchants via REST API.

Please see the following post to answer your questions about configuring multiple providers, payment gateways, and merchants with this API:

Yes, we have to handle the situation of maintaining multiple Apple Pay domain verification files at my employer as well. We just swap them out as needed since you can only host a single domain verification file at a time. In practice, it looks like once the file is verified, Apple doesn't seem to check it again since your domain is already validated. As our company continues to integrate with different payment gateways / providers, we just replace the domain verification file with the new one and verify the new one.

Any news for it , it seems that check is done now each time with the verification of the domain and one account needs to have one domain . The same domain cannot be registered for multiple accounts

Did anyone figure this out? Replacing the file worked for me as well, but that feels more like a short-term solution rather than an actual fix. Has anyone seen this issue pop up again after swapping files? Can you please update here if you find a permanent solution. @magnus83 @RB3207 @Hunt_Welch
