Recurring Payments

A recurring payment is a credentials-on-file (COF) transaction in a series of payments that you bill to a customer for a fixed amount at regular intervals that do not exceed one year between transactions. The series of recurring payments is the result of an agreement between you and the customer for the purchase of goods or services that are provided at regular intervals. Recurring payments are also known as subscriptions.
Recurring payments are covered in the "Processing Payments Using Credentials" section of the
Payments Developer Guide
