# Facebook Ads

Export cohorts from devtodev to Facebook Ads to build Custom Audiences for Meta campaigns

## **Setup**

1. Go to: `Settings → 3rd Party Sources → Cohort Export`
2. Click the ✎ icon next to **Facebook**
3. Fill in the fields:
   * **Account ID** – your Facebook ad account ID (numeric, usually 10–15 digits)

{% hint style="info" %}
**Where to find Ad Account ID**

* Log into Meta Ads Manager
* Check the URL — the ID appears in the `act=XXXXXXXXXXXX` parameter

For help finding your Ad Account ID, [see Facebook documentation](https://www.facebook.com/business/help/2534657046763437,).
{% endhint %}

4. Click `Login with Facebook` to authorize.

*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](/integration/integration-of-sdk-v2/sdk-integration.md) and **Advertising ID** is available in the user profile before the cohort is exported.&#x20;

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.devtodev.com/3rd-party-sources/cohort-export/facebook-ads.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
