# Onboard and offboard

> How to import employee rosters, track joiners and leavers, and keep profiles current using the Merge HRIS API.

---

#### Onboard your user

Your user signs into your app, and navigates to the screen to initialize the onboarding employees function through your integration with Merge. Merge begins syncing Employee data.

> **Note**
>
> Configure [Field Mappings](/merge-unified/supplemental-data/field-mapping/overview) in Merge Link (end-user) or Merge Dashboard to bring in custom fields relevant to an an end-user, if needed.

> **Note**
>
> Before your user Links, use Scopes in the Dashboard to configure what information Merge and your app is able to access from a third-party platform.

#### Pull employee data from Merge

Your app is able to get the data it needs with:

* Use [**GET** /Employees](https://docs.merge.dev/hris/employees) to perform an ingest of an end-user's current employees, and onboard them onto Center's platform.
* Use endpoints like [**GET** /Groups](https://docs.merge.dev/hris/groups), [**GET** /Locations](https://docs.merge.dev/hris/locations), [**GET** /Employments](https://docs.merge.dev/hris/employments) to understand additional dimensions about employees for grouping in your product, or auto-provisioning.

#### Refresh data regularly to track joiners and leavers

After your initial sync, regularly call the **[GET /Employees](https://docs.merge.dev/hris/employees)** endpoint using the `modified_after` query parameter to track employees joining & leaving, as well as changes to existing employees to keep user tables up to date.

The fields `status`, `start date`, and `termination date` will all allow you to precisely track joiners and leavers.

#### Give users value, faster

* With onboarding handled automatically, allow your users to access the parts of your application they drive value from.
