I am using a system called autopilot that uses a different method of paging where the base URL needs to be appended instead of a query parameter. See here:
https://autopilot.docs.apiary.io/#reference/api-methods/get-contacts-on-list
I was actually able to do a workaround by using a separate Enrichment call for each page > 1 and then combining all of the results together. It works but it is fragile.
Hoping that you might add this as another paging option.
Thanks!
