Filter with `kind` and/or `status`, sort by `code` or `balanceCents`, and walk with `page`/`pageSize` (max 100) until `pageCount`. Use this to survey or reconcile the book; to resolve ONE card a customer is holding, use the by-code lookup instead — a scanned code is not searchable here. ## OpenAPI ````yaml /openapi.json get /v1/giftcards openapi: 3.0.3 info: title: Solya POS API version: 1.0.0 description: >- The Solya POS backend HTTP surface.
