*To disable the integration, turn off the toggle.*

### **User Identifier**

* Set a [custom property](https://docs.devtodev.com/integration/integration-of-sdk-v2/setting-up-events/user-profile#custom-user-property) in devtodev: `braze_id`. This identifier ensures accurate tracking and segmentation of users during data export.
* `braze_id` must match the **Braze user ID:** a unique user identifier that is set by Braze, see [Braze documentation](https://www.braze.com/docs/api/basics/#user-ids).
* Make sure this property is set before cohort export.
