Hello!I am currently trying to verify my domain for Apple Pay so that we may begin Sandbox testing as soon as possible. Apple Developer directs us to upload the file at [domain].demandware.net/.well-known/apple-developer-merchantid-domain-associationWe have created out Payment Processing Certificate, our Merchant Identity Certificate, and Merchant ID. We have staged Apple Pay in Business Manager Staging, including registering the Sandbox domain.Is the /.well-known/ path one that we must create ourselves? This seems to be the only step that does not have clear direction.Thank you in advance for any support!
