By connecting these systems, you can efficiently target and re-engage your audience with highly personalized ads that resonate at every stage of the customer journey. This integration empowers you to: - **Leverage real-time insights**: Use up-to-date, first-party customer data to create dynamic and precise Custom Audiences on Meta. - **Boost campaign ROI**: Optimize ad spend by focusing on the most relevant segments, such as high-value customers, recent purchasers, or users likely to churn. - **Enhance cross-channel consistency**: Align your messaging and offers on Meta with other channels to deliver cohesive and personalized customer experiences. - **Automate audience updates**: Keep your Meta Custom Audiences automatically refreshed with the latest data, ensuring your targeting remains relevant and impactful.

Go to [Facebook Developer portal](https://developers.facebook.com/apps/) and create a new app. 1. Under **App details**, give the app a display name and a contact email. 2. Under **Use cases**, select **Measure ad performance data with Marketing API** 3. Under **Business**, you can connect your business portfolio now or later 4. Under **Overview**, review the details and click **Create app**. 2. In your App Dashboard, select **App settings →** **Basic** from the left sidebar. Fill in the required fields, making sure to provide a valid Privacy Policy URL, Terms of Service URL, and User Data Deletion URL, and save the changes. #### Step 2: Create admin system user and access token 1. Go to [Facebook People Settings](https://business.facebook.com/settings/people), and select the linked Business Portfolio. 2. Go to**Users → System Users**. 3. Add a new Admin System User or use an existing one. 1. If you add a new System User, make sure its role is set to Admin. 4. Select the Admin System User and click **Generate token**. 5. Select the app that you previously created, and click **Next**. 6. Set the token to expire Never, and click **Next**. 7. Copy the token and save it in a secure location.

Confirm the token settings: - **Type**: System User - **Expires**: Never #### Step 3: Publish the app When you have set all the configurations correctly, publish the app you created. 1.

Click **+ New Connector.** 3. Select **Facebook.** 4. Use the same access token that was created in the Meta configuration process. You can set up multiple Meta connectors connected to different Ad Accounts and/or types of identifiers (see Payload type) for the same Ad account. ### Step 2: Add the destination connector to an Audience or Journey 1. On the Data Activation platform, select **Audiences** in the left-side navigation bar. 2. Configure the criteria users should meet to become part of the audience in step 1. 3. Add your Meta connector in step 2 of the audience setup. Make sure profile identifiers mentioned in the Quick Connector Overview are collected in the Data Activation before using this connector. ## Error handling Meta error codes are reported on the Data Exchange section of the audience or journey using the following error codes: - Timeout - Other error - Invalid credentials For more information, see the Meta API documentation: - [Meta Marketing API](https://developers.facebook.com/docs/marketing-api/error-reference) - [Meta Custom Audiences documentation](https://developers.facebook.com/docs/marketing-api/reference/custom-audience/users/) If your error isn't listed above, consult the Meta Marketing API error reference documentation for investigation. ## FAQs **How do I use the external ID as payload type?** The Data Activation team is currently assessing whether the external ID provides any added value compared to first-party identifiers such as cookies created by the Meta pixel or email/phone hash. **Can I use the external_id in combination with CAPI/pixel?** Meta uses different storage for custom audiences compared to CAPI/pixel; an external_id sent using pixel cannot be used in Custom Audiences and vice versa. ## More resources - [How to build audiences](/v1/docs/how-to-build-audiences) - [How to build journeys](/v1/docs/how-to-build-journeys) - [How to measure goals and outcome signals](/v1/docs/how-to-measure-goals-and-outcome-signals)
