With Amplitude's Split integration, you can export your Amplitude cohorts and use them as segmentation and targeting criteria in Split. From there, you can create splits or feature flags for specific segments of users defined by your Amplitude data.

## Set up the integration

### Split setup

To set up the integration, collect the following information from your Split dashboard first.

1. From your Split dashboard, select your account and click **Admin Settings**.
2. In admin settings, navigate to the *API Keys* tab and click **Add API Key**. Set the key type to *Admin*. After it's created, copy the key.
3. Specify the workspace to export your Amplitude cohorts to. Click **Workspaces** in the left sidebar and copy the workspace ID.
4. Click **View** for the workspace you selected. From inside that workspace, select the **Environments** tab, and copy the appropriate environment ID.
5. Select the **Traffic Type** tab and copy the traffic type ID.

### Amplitude setup

1. In Amplitude Data, click **Catalog** and select the **Destinations** tab.
2. In the Cohort section, click **Split**.
3. In the *Connect to Split* modal, enter the following information you collected from Split:
      - The access token (API Key)
      - Workspace ID
      - Environment ID
      - Traffic type ID
4. Map the user identifier Amplitude uses to sync with Split.
5. Save your work.


{% callout type="note" title="" %}
Choose a matching identifier in Amplitude and Split. This is often `userID`.
{% /callout %}

## Send a cohort

After you connect Split and Amplitude, you can sync any Amplitude cohort to it.

1. In Amplitude, open the cohort you want to export. Click **Sync**, and choose **Split**.
2. Choose the API target.
3. Select the sync cadence.
4. Save your work.

{% callout type="note" title="" %}
The Split integration supports ingestion of cohorts with fewer than 100,000 users.
{% /callout %}

After Amplitude syncs the cohort to Split, it appears in your Split workspace in the *Segments* section. You can then use this segment for targeting rules in feature flags and splits you set up in Split.
