ResourcesReward Grants
Overview
Issue eligible customer rewards idempotently and inspect grant history.
Reward grants are the irreversible issuance boundary. The API verifies that the rule and customer belong to the selected store, recalculates current eligibility, and relies on database uniqueness for each rule/customer pair. Repeating an issuance request returns the existing grant and never duplicates outputs.
Internal evaluation snapshots and idempotency keys are intentionally omitted from API responses. Explicit manual revocation is not exposed because redeemed coupons and spent wallet credit cannot always be reversed safely; supported revocation is handled by order-lifecycle reconciliation.
Use the reward API token ability and the X-STORE header.
