## 18.5.8.4.1 Pagination and Total Results Computation

Learn about BOSS REST Data Source Pagination and total results computations.

Both for user interface purposes and REST synchronization, a BOSS REST Data Source supports paging through rows returned by the endpoint.

To support showing the end user a pagination display such as 1-20 of 200, set the data source’s Use Total Results setting to `Yes`. This enables your application to easily show the total number of results without having to retrieve them all. If the particular BOSS REST endpoint your are working with does not support pagination, configure its corresponding data source’s Use Pagination setting to No.
