[BK ES Migration] Loyalty API - V1 Current

This is the current version we recommend using for Loyalty API integration for both POS and Kiosk vendors. This supports multi-scanning and showing offers on the Kiosk UI.

Brands and markets want either their pre-existing or new kiosk implementations to work within the in-store loyalty experience. The kiosk user experience will have some slight nuances that we need to account for relating to the Loyalty APIs how Kiosks integrate with them.

Desired Kiosk User Flow

User identifies themselves as a loyalty user at kiosk using identification mechanism (i.e. 6-digit short, code, QR code, etc.)
1. The identification may include pre-selecting rewards and/or offers within the app similar to the in-store loyalty experience
Upon successful identification:
1. Any pre-selected rewards and/or offers are injected into the Kiosk order
2. User’s information is populated within the Kiosk (i.e. name, points balance)
User is able to proceed with placing their order by selecting desired items/combos
User is able to browse and select additional rewards they wish to redeem
1. Kiosk will display rewards based on user’s available point balance
User completes order at Kiosk
User picks up food at pick-up counter

Transaction Validation (POST)

Use Case: Kiosk sends the Loyalty API a preliminary version of the user’s order so that the Loyalty Platform can evaluate the order and determine if the user meets eligibility requirements of any included incentives (Rewards or Offers). This request should be an exact mirror of what the POS expects to send when they actually claim the transaction.

Transaction Update (PUT) - Claim / Commit

Use Case: Kiosk sends this transaction request with the order details to update the loyalty transaction. If the Kiosk states this transaction should be claimed, this will result in the user earning and redeeming eligible points.
