Use it to browse or to find a member id; when you already hold a CUSTOMER id and want the live balance, call `getLoyaltyAccount` instead — that one recomputes from the ledger. Filter with `tier` (e.g. `Or`) and `status` (`active` / `suspended`), order with `sortField` (`customerName` / `lifetimePoints`), and walk with `page`/`pageSize` (max 100). ## OpenAPI ````yaml /openapi.json get /v1/loyalty openapi: 3.0.3 info: title: Solya POS API version: 1.0.0 description: >- The Solya POS backend HTTP surface.
