  • 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.
  • 404 resource_missing — the referenced resource does not exist or is not visible to your key.

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.
