Customer-Initiated Installment Payments with PAN

The first transaction in an installment payment is a customer-initiated transaction (CIT). Before you can perform a subsequent merchant-initiated transaction (MIT), you must store the customer's credentials for later use. Before you can store the user's credentials, you must get the customer's consent to store their private information. This process is also known as establishing a relationship with the customer.

In the CIT authorization response, capture the value in the

processorInformation.networkTransactionId

field. You must include the network transaction ID in subsequent MIT authorization requests.
