What you build

The customer's service reads each booked sale from the feed and credits its own ledger; the ledger may live in iVendNext as your manifest's records.

The kit's samples read the shared feed, whose key is not limited to one app (a feed scoped to your app is an extension point, chapter 9).
Loyalty points are credited when the service is back: a sale waits in the feed while it is down.

Each booked sale earns in your own programme, shortly after it is booked.

Tell the customer the 2 limits above, and write them into the proposal.
Follow the recipe: A customer's own loyalty programme: the rules outside, the records inside.
Copy the sample: S22 — Customer-owned loyalty (pp_lyl): your logic outside, the records inside the shop, and change it.
Build and test it on your sandbox (request one if you have none; what is on it).
Run the checks: your own tests, the kit's checks and the money kit's release gate (testing and release).
Release through the customer's own release gate (14. Testing and release); an app other shops install goes through the App library.

Stop your service for a while and start it again: it must catch up from the event feed, missing nothing.
