Pagination

All list endpoints return 20 results by default, configurable up to 100 via the limit parameter. In the sandbox environment, endpoints return a fixed set of results with no pagination — limit and offset parameters are ignored. All endpoints return a maximum of 20 results, except the List Payers endpoint.
