Apple Pay is a mobile payment service by Apple Inc. that allows users to make payments in person, in iOS apps, and on the web.

We have integrations both directly through Adyen and through Gravy using the Adyen backend. There is also native iOS payments that are using the direct Adyen integration.

Apple Dev Accounts

We share some Apple Pay setup with the iOS team. Not everyone has access to the full config so if something is needed ask the iOS team and they can help out.

Verifying Merchant Domains (payments.wikimedia.org)

We have to do this yearly? Adyen and Gravy use different files, but the process on the apple side is the same.

Navigate to the Merchant Identifiers list here
Select the 'Wikimedia Apple Pay Merchant ID' record to edit
On the Edit or Configure Merchant ID page, Scroll down to the Merchant Domains block
On the right, click Verify
Download the new verification file payments.wikimedia.org
In payments-wiki, update the contents of .well-known/apple-developer-merchantid-domain-association.txt with the contents of the new verification file you just downloaded
Example here: https://gerrit.wikimedia.org/r/c/mediawiki/core/+/1123424
Deploy that change
Reverify by clicking 'OK'

It will take a few seconds to process, and then if successful, you will be redirected back to the Edit or Configure Merchant ID page where Verification Expires date should be updated.
