**Important**
Use this integration if you use the Optimizely Data Platform (ODP) [CDP audience sync](docId\:jUx2QP7GrcRvtlRjQeXQ7) environment. If you use ODP as your main customer data platform, see [Integrate Twilio Segment Optimizely Data Platform destination](docId\:ZAMml-0IkdLCqLORkvxgR).
:::

Connect your Twilio Segment Engage audiences to Optimizely Data Platform (ODP) for advanced audience targeting with Optimizely Web Experimentation, Optimizely Feature Experimentation, and Optimizely Content Management System (CMS) visitor groups.

After you complete the setup below, this integration syncs your Twilio Segment Engage audience updates to ODP in near real-time.

## Prerequisites

- Twilio Segment account with access to Engage
- ODP account
- Optimizely Web Experimentation, Optimizely Feature Experimentation, or CMS 11 or 12 account

## Enable the integration

1. In ODP, go to **Data Setup > App Directory**.
2. Select the **Twilio Segment** app.
3. Click **Install App**.
4. On the **Settings** tab, click **Generate** and copy the token that displays.

### Add the token in Twilio Segment

1. In Twilio Segment, go to **Connections > Catalog > Destinations > Destination Actions**.
2. Search for **Optimizely Advanced Audience Targeting** and select **Configure Optimizely Advanced Audience Targeting**.
3. Select your **Engage Space** as a source. This destination only works when an engage space is configured as a source.
4. Click **Confirm Source**.
5. On the **Settings** tab, paste your ODP API token from step 4 above into the **Api Key** field.
6. Select your **Region**, toggle **Enable Destination** to **On**, and click **Save Changes**.
7. On the **Mappings** tab, click **New Mapping**, then click **Sync Audience**.
8. In the **Select mappings** section (section 3), configure the user ID you want to send to ODP. This should be the same user ID you use in Optimizely Experimentation.
9. Click **Save**.
10. Toggle the **Status** to **Enabled**. This enables the action.

### Sync Twilio Segment Engage audiences to ODP

1. In Twilio Segment, go to **Engage > Audiences**.
2. Select the audience you want to sync and click **Add Destination**.
3. In the window that displays, click **Add destination** again.
4. Search for and select **Optimizely Advanced Audience Targeting**.
5. Ensure **Send Identify** is enabled.
6. Click **Save Settings**.

This syncs your Twilio Segment Engage audience to ODP, including all updates to this audience going forward.

To view your Twilio Segment Engage audiences in ODP, go to **Customers > Audiences**. Your synced audiences will have Twilio Segment appended to the beginning. For example, **Twilio Segment - Audience Name**.

For more details on destination and audience settings in Twilio Segment, see [Twilio Segment's documentation](https://segment.com/docs/connections/destinations/catalog/actions-optimizely-advanced-audience-targeting).

## Use your Twilio Segment Engage audiences in other Optimizely products
