Connecting Party integration scenario

Depending on the PCI compliance and business requirements, Connecting party integrates to Payment Gateway via Server-to-Server APIs, Hosted payment form APIs or a combination of them. Each integration option is provided in API Use-Cases section, and each API Use-Case provides clear instructions which API commands to call on each stage of the payment flow and how to handle their results. All APIs are asynchronous. Common utilities section provides added value services which might be enabled by request. FAQ page helps to resolve common issues during Connecting Party integration.

Denumtech support manager configures Projects with connected Endpoints and Endpoint Groups (if needed) for one or multiple merchant accounts of Connecting Party in Payment Gateway. For API integration, Connecting party receives the following data from Denumtech. This data can be provided independently for sandbox (test) and production environment. Any additional required credentials are mentioned in relevant API Use-Cases.

Main required credentials are:
  1. Endpoint IDs per currency or Endpoint Group IDs for multicurrency integration (see reference schema below).

  2. Merchant login.

  3. Merchant control key.

  4. Integration scenario documentation.
