Enrolling in Apple Pay

Apple Pay is a digital payment service that enables users to make secure and convenient transactions using their Apple devices. Users can add their credit or debit cards to the Wallet app and use them to pay online or in apps in a safe and convenient consumer experience.

To enable Apple Pay you must first host a public certificate on your web page and then pass your merchant name and domain name to Apple. Apple crawls out to your web page to validate the presence of this certificate to ensure the web pages are properly vetted and registered with Apple.

Follow these steps to validate your domain and enroll in Apple Pay:

Navigate to

Payment Configuration > Unified Checkout

.

In the Apple Pay section, click Set Up
.

Follow the link to download the certificate.

Upload the apple-developer-merchantid-domain-association
certificate file to your web server at:

/.well-known/apple-developer-merchantid-domain-association

You must verify that the file is accessible through HTTPS. You can validate this by visiting

https://<your-domain>/.well-known/apple-developer-merchantid-domain-association

.

Click

Verify Domain

.

Enter the domain name where you are hosting Apple Pay. This must be the same domain to which you uploaded the public certificate.

Your domain is now verified for Apple Pay.
