## Trigger configuration

To configure the trigger with this Object:

1. Select the **Credential to connect with**. Select an existing or create a new [Facebook App credential](../../../credentials/facebookapp/).
1. Enter the **APP ID** of the app connected to your credential. Refer to the [Facebook App credential](../../../credentials/facebookapp/) documentation for more information.
1. Select **Permissions** as the **Object**.
1. **Field Names or IDs**: By default, the node will trigger on all the available events using the `*` wildcard filter. If you'd like to limit the events, use the `X` to remove the star and use the dropdown or an expression to select the updates you're interested in.
1. In **Options**, choose whether to turn on the toggle to **Include Values**. When turned on, the node includes the new values for the changes.
