Pay.UK have made an API (Application Program Interface) available to the RCMS (Reimbursement Claims Management System) that allows firms to directly integrate the end-to-end automated claims workflow RCMS functionality into their own systems, circumventing the need to access the system through the user interface.
The purpose of this survey is to forecast when and how many PSPs plan to integrate the API so that Pay.UK can ensure adequate testing support is in place.
More details on the API can be found here.
