You can use these credentials to authenticate the following nodes with Facebook.

- [Facebook Trigger](#)


## Prerequisites

- Create a [Facebook](https://www.facebook.com/) account.
- Sign up for [Meta for Developers](https://developers.facebook.com/) with that account.
- Create at least one [Meta app](https://developers.facebook.com/docs/development/create-an-app).


## Supported authentication methods

- App access token


## Using app access token

To configure this credential, you'll need:

- An app **Access Token**: Refer to the Meta instructions for [Your First Request](https://developers.facebook.com/docs/graph-api/get-started#get-started) to generate the App **Access Token**.
- *Optional:* An **App Secret**: To add an **App Secret**, go to your App Dashboard **Settings > Basic**. Refer to the [App Dashboard Settings documentation](https://developers.facebook.com/docs/development/create-an-app/app-dashboard#settings) and the [App Secret documentation](https://developers.facebook.com/docs/facebook-login/security#appsecret) for more information. You will need to re-enter your Facebook account credentials to show the **App Secret**.


When you add an App Secret, Mosaic Workflows will verify this signature to validate the integrity and origin of the payload.
