  • Collect coupons, credit cards, memberships, loyalty cards, and more in one place.
  • Manage the payment instruments that they use in the app and music store.
  • Link items in the Wallet to apps on their phone.
  • Make contactless transactions, using Near-Field Communication (NFC), in some markets.

The Wallet API offers full programmatic access to the Wallet. It allows you to create, read, update, and delete Wallet items to implement Deals or Payments.
Deals are useful to manage coupons, loyalty cards, Payment instrument manage a balance on an account maintained by your backend.
