List transactions

List all transactions for the authenticated merchant. Transactions represent the unified financial truth — every sale, refund, void, capture, dispute, and adjustment.

GET/transactions

List all transactions for the authenticated merchant. Transactions represent the unified financial truth — every sale, refund, void, capture, dispute, and adjustment.

starting_after and ending_before are mutually exclusive: supply at most one. Sending both is rejected with 400 parameter_invalid. A cursor must also name a transaction belonging to the authenticated merchant; an unknown id is rejected with 400 resource_missing.

  • GET /transactions/{id} — Get transaction by ID

Common errors

  • 400 invalid_request — malformed payload or failed validation.
  • 401 authentication_error — missing, invalid, expired, or revoked credential. Codes: authentication_failed, invalid_api_key, expired_api_key, api_key_revoked, session_invalid, merchant_required. Carries a WWW-Authenticate: Bearer challenge.

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.
