How do I enable Apple Pay on the Simple Widget?

Once you have embedded the simple widget on your site, here are the 3 steps to ensure Apple Pay is available for your donors:

1) To begin, your application must be served over HTTPS.

2) Please download this domain association file and host it at

/.well-known/apple-developer-merchantid-domain-association on your site.

For example, if you're registering, make that file available at You'll know it's correctly hosted if you see the file when you go to that URL on your domain.

3) Email with the name of your nonprofit in the subject line, include the URL where your widget is hosted in the body of the email, and we will register your domain as approved on our end.

Keep in mind that Apple Pay will only appear on Apple devices that have it enabled using Safari.
