There are two ways to accept payment for an “MCP” sale:

• Accepting payment using a regular transaction: Process a regular payment transaction using the converted MCP values and MCP currency.
  Follow the transaction processing steps for the relevant Nuvei payment product:
  • For Out-of -the-box solutions: Processing a regular Payment Transaction using MCP Values for the Cashier or Checkout Page products (see below).
  • For API building blocks: Processing a regular Payment Transaction using MCP Values for Workflows which use Nuvei Web SDKs and REST APIs (see below).
• Accepting payment using a DCC transaction: Process as a Dynamic Currency Conversion (DCC) transaction.

Processing a regular Payment Transaction using MCP Values for the Cashier or Checkout Page products

The regular payment workflow will be used to accept payment when:

• You are not registered for DCC, or
• The customer’s payment method does not allow DCC transactions, or
• The customer’s home currency is not one of your registered DCC currencies.

The system automatically initiates a regular payment request, sending the final “check-out amount” (displayed in the customers home currency) as the transaction amount, and the MCP currency as the transaction currency.

Processing a regular Payment Transaction using MCP Values for Workflows which use Nuvei Web SDK and REST APIs

1. First check if the regular payment workflow is the appropriate way to accept payment.
   Use the regular payment workflow to accept payment when:
   • You are not registered for DCC, or
   • The customer’s payment method does not allow DCC transactions, or
     (Note:  You can use the /getCardDetails method to check this.)
     
   • The customer’s home currency is not one of your registered DCC currencies.
     (Note: You can use the /getDccDetails method to check this.)
2. Process a regular payment workflow sending the final “check-out amount” (displayed in the customers home currency) as the transaction amount, and the MCP currency as the transaction currency.
   (Note: For details of the regular payment workflows see: Web SDK Flow, 3D-Secure MPI-Only Flow for Web SDK, or Server-to-Server Flow.)
   Later, when the transaction is finally settled, the transaction amount paid to you will include the additional exchange markup and other fees, (which were “built into” the item prices).
   Note, that the exchange markup and fees are not shown as separate values anywhere in the transaction.
   So, you will need to settle these fees with Nuvei according to your agreement with Nuvei.
