  Versapay returns a numeric gateway response code on Order Transactions (verify,
  sale, auth, capture, refund, void, credit). The code appears on a `response_code`
  key (with related `gateway_error_*` keys) in the transaction payload. The
  authoritative, complete list is served at runtime from the (auth-gated)
  reference-data endpoint below rather than enumerated in the OpenAPI, so only the
  envelope, the documented example code, and the retrievable source are captured
  here — the full code table is intentionally not fabricated.
envelope:
  fields:
    - success        # boolean; false on a declined/failed transaction
    - response_code  # numeric gateway response code (e.g. 211)
    - gateway_error_*  # related gateway error detail keys
  location: Order Transactions API transaction payload
reference_endpoint:
  operation: GET /api/reference_data/v1/response_codes
  description: Retrieve the list of supported error/response codes returned on the response_code key.
  auth_required: true
cvv_response_codes:
  source: sandbox/versapay-sandbox.yml
  note: CVV verification result codes (P/M/N/S/U) are documented and testable in UAT.
avs_response_codes:
  source: sandbox/versapay-sandbox.yml
  note: AVS verification result codes (A/G/N/R/S/U/W/X/Y/Z/I/E/D/M) are documented and testable in UAT.
decline_codes:
  - code: '211'
    meaning: Example gateway response code documented in the Reference Data section (declined transaction).
