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

### **User Identifier**

Facebook Ads cohort export in devtodev uses only the **Advertising ID**:

* For Android: **GAID** (Google Advertising ID)
* For iOS: **IDFA** (Identifier for Advertisers)

Make sure the [SDK is integrated properly](https://docs.devtodev.com/integration/integration-of-sdk-v2/sdk-integration) and **Advertising ID** is available in the user profile before the cohort is exported.&#x20;
