Hi Brock,
We don't currently have a specific endpoint dedicated to unenrolling users, however, you can utilize existing endpoints to do so. During the enrollment process, we are creating a customer, user, and user logon for that user. In this case, it would suffice to delete these entities via our Delete User (see https://docs.q2api.com/docs/q2-caliper-api/42b9c8d4af217-delete-user) and Delete Customer (see https://docs.q2api.com/docs/q2-caliper-api/9291be24d2f67-delete-customer) endpoints.
Thanks,
Solène
