Preparing merchant domains for verification
Host a domain verification file on each domain before requesting registration.
Overview
Before making a Register Merchant request, prepare each domain included in the request for verification.
Download and distribute to each merchant that has a domain registered via the Web Merchant Registration API. If merchants will be using Apple Pay via pages hosted on your domain, host this file on your own domain also.
You can find the domain-verification file for each of your payment platform integrator IDs in your Apple Developer account.
Host the domain-verification file
Host your domain-verification file at the following path for each domain you’re registering:
https://[DOMAIN_NAME]/.well-known/apple-developer-merchantid-domain-association
Make sure the domain-verification file is in place before invoking Register Merchant. Use the domain-verification file associated with the payment platform integrator ID and payment platform identity certificate used to secure the Register Merchant request.
Apple Pay servers don’t require domain verification in the sandbox environment.
