CustomerLink allows you to create, update and delete tokens. These tokens can be stored on your database without the risk of storing clear text credit card or banking details. You can then use these tokens to either do one-time transactions, or recurring transactions where you manage the recurring schedule.
CustomerLink also allows you to set up recurring schedules where iATS will manage the recurring schedule. The results of these recurring transactions can be pulled out of our server using our ReportLink services. Our webservices allow you to modify these schedules (card data, start and end dates, etc.) via the API.
