The Pay with Points API lets Citi customers use their Citi Points to pay for all or part of a transaction on your app. To simplify integration, transaction payments are processed through your existing payment gateway. A matching statement credit is then applied to the customer's Citi account, usually within 1-3 days.
The API allows you to:
Accept Citi Points as a new form of payment.
Activate points payment using basic customer information.
Process Citi Points payments through your current payment gateway.
This API is part of Citi Open Banking, a set of APIs that allow you to connect to core Citi financial functionality.
