Pagination

Offset-based with limit (default 25, max 100) and offset. The response pagination block includes total and hasMore. See the pagination guide for SDK auto-paging helpers.

Authorization

x-api-key<token>

Your RevKeen merchant API key. Create and manage keys in Dashboard → Settings → Developer. Use rk_sandbox_* for staging/test and rk_live_* for production. The same key may be sent as Authorization: Bearer <key> if that suits your HTTP client better. A missing, invalid, expired, or revoked key returns 401 with a WWW-Authenticate: Bearer challenge; a valid key without the required scope returns 403.
