Error message

Domain verification failed. Make sure the Apple Pay domain association file is publicly accessible at the top-level of your domain, and returns at 200.

Common causes

• The domain association file isn't hosted at the correct URL.
• The file returns a non-200 status (e.g. 404, 500).
• The request to the file is redirected to another URL.
• The file isn't accessible to the Apple Pay servers.

Troubleshooting

• Download the Apple Pay domain association file from the developer docs and upload it to your web server.
• Check that your file is served at /.well-known/apple-developer-merchantid-domain-association. For example, if your website is example.com, make the file available at https://example.com/.well-known/apple-developer-merchantid-domain-association.
• Make sure your domain isn't behind a proxy or redirect, and it's publicly available to the Apple Pay servers.
