Handling partial payment issues

A transaction request may return a partial payment when the customer’s card has insufficient funds to complete the transaction.

The POS must examine the payment response and see if an issues.partialPayment object was returned. If a partial payment occurred, the POS must notify the merchant and then provide either or both of the following options:

  • Accept the partial payment and start a second transaction to pay the remaining balance with a different card or other form of payment
  • Void the original transaction and allow the customer to retry the payment with a different card or other form of payment
