# Get the Details of All Users

### Description

This API enables you to fetch the details of all [Catalyst applications users](https://docs.catalyst.zoho.com/en/cloud-scale/help/authentication/user-management/introduction/) of a particular application through Pagination. **Pagination** allows you to retrieve the user list in pages through an iteration of API calls.

For example, if you require user records to be fetched in batches of 200 as individual pages, you must include a `start` and an `end` parameter in your request. You can set the start index as 0 using the `start` parameter, and specify the maximum number of users to be fetched as 200 using the `end` parameter. To fetch the next set of user records, you can execute another API call by setting the `start` index as 200, and specifying the number of user records in that page using the `end` parameter accordingly.
