# Facebook Triggers

> The triggers available for Facebook automations — comments, Live, Page mentions, and referral links.

## What is this?

Facebook automations have their own trigger types, on top of the generic ones covered in [Triggers](/workspace/automation/triggers/overview). Most Facebook flows start with activity on your Page rather than a direct Messenger message.

## What can I do here?

| Trigger                                  | Runs when…                                                                                    |
| ---------------------------------------- | --------------------------------------------------------------------------------------------- |
| **User comments on your Facebook Post**  | Someone comments on your Facebook post                                                        |
| **User comments on your Facebook Live**  | Someone comments during your Facebook Live                                                    |
| **Someone @mentions your Facebook Page** | Someone @mentions your Page in a post or comment — best used with FB Private Reply            |
| **User clicks a Facebook referral link** | Someone opens Messenger from an m.me link, ad, or other referral entry with a `ref` parameter |

## How to use it

<Steps>
  <Step title="Create the workflow on the Facebook channel">
    Go to **Automation → Create Automation**, choose your Facebook channel, and pick the trigger.
  </Step>

  <Step title="Scope a comment trigger">
    For **Post** and **Live** comments, select which post or Live the trigger watches — or leave it open to all of them.
  </Step>

  <Step title="Add comment and mention steps">
    Comment and mention triggers unlock the matching steps — reply publicly, send an FB Private Reply into Messenger, or moderate the comment. See [Facebook Steps](/workspace/automation/steps/facebook-steps).
  </Step>

  <Step title="Test, then activate">
    Trigger the real event once (comment, mention, or referral click) and confirm the flow runs, then activate — see [Manage Live Flows](/workspace/automation/manage-live-flows).
  </Step>
</Steps>

<Tip>
  Pair **Someone @mentions your Facebook Page** with **FB Private Reply** to move the conversation from a public mention into Messenger.
</Tip>

## Troubleshooting / Technical Notes

* **The flow never runs.** Check that it's **Active**, points at the correct post or Live, and that the Facebook Page is still connected.
* **Comment or mention steps are missing from the palette.** They only appear when the trigger is a matching comment or mention trigger.
* **The referral trigger doesn't fire.** Confirm the link includes a `ref` parameter and points to your Page's Messenger entry point.
