Creating a Follow on Subscription from an Existing Transaction

You can create a subscription using an existing successful transaction by specifying its request ID in the path. This method eliminates the need to provide a customer token.
You can use an existing or one-time plan.
The start date must be in coordinated universal time (UTC) in this format: YYYY-MM-DDThh:mm:ssZ. The T separates the date and the time. The Z indicates UTC. For example,
2023-08-11T22:47:57Z
indicates August 11, 2023, at 22:47:57 (10:47:57 p.m.). For subscriptions created on the start date, set the time to the current time and day in your time zone.
Follow these steps to create a subscription:
  1. Create the request with the required API fields.
  2. Send the request to one of these endpoints:
    Production:
    POST https://api.cybersource.com/rbs/v1/subscriptions/follow-ons/{requestId}
    Test:
    POST https://apitest.cybersource.test.com/rbs/v1/subscriptions/follow-ons/{requestId}
  3. Verify the responses to make sure that the request was successful. A 200-level HTTP response code indicates success.
