There are few steps needed in order to perform a recurring Cards payment via API (Merchant functions as the scheduler):
- You need to create a multiple use token ID first here and do not forget to tick / check "is multiple use" box.
- Once a token ID has been created, you need to authenticate that token here. Please note that for a recurring payment, the initial payment must be authenticated first (the second payment onward will not need to be authenticated).
- When that multiple use token has been successfully authenticated, you can proceed with the recurring payment charge via API here. In the charge request, you need to add the following parameters:
- Token ID
- Authentication ID
- "is_recurring" as true
