# Facebook Comment Automation

Automatically reply to Facebook comments and send follow-up messages through Messenger to engage users directly from your posts and reels.

### **Before you begin:**

Ensure your Facebook Page is integrated with your AiChat chatbot.

If you have not connected your Facebook Page yet, complete the [Facebook Page connection setup](/social-messaging-channels/facebook/connecting-facebook) first.

## How Facebook Comment Automation Works

When a user comments on a monitored Facebook post or reel:

1. AiChat detects the comment
2. The automation checks if the comment matches your trigger rules
3. AiChat replies publicly to the comment (optional)
4. AiChat sends a private message to the user's Facebook Messenger inbox (optional)

**Limitations:**

* **First Level Only:** The bot only replies to new comments, not replies made to existing comments.
* **DM Limit:** To prevent spam, the bot will only send one private Messenger DM per trigger event.

 

## Configuration Guide

### Step 1: Create & Select Your Post

* **Navigate:** Go to **Flows → Comment Automation** and click **Create comment automation**.
* **Name it:** Enter an Automation Name and an optional description.
* **Pick Content:** Select the published or scheduled Posts or Reels you want to monitor. You can use the search bar to find posts by their post caption or ID.

### Step 2: Define the Trigger

Decide exactly what a user needs to type to start the automation.

* **Rule Type:** Choose Any Comment (triggers for everyone) or Keywords (triggers only for specific words).
* **Keywords:** List variations like "#interested", "price", or "details".
* **AI Matching:** Enable Contextual Matching so the bot understands intent even if the user has a typo.

* **Media (Optional):** You can require users to include an Image or Video in their comment to trigger a response.

* **Fallback:** Set a Default Reply for comments that don't match your keywords or arrive outside of your schedule.

### Step 3: Set Your Responses

Choose how the bot will interact with the user.

* **Public Reply:** Type a message that appears directly under the user's comment (e.g: "We've sent you a DM!").
* **Private DM:** Select a Custom Message or a pre-made Automated Flow to be sent to the user's Messenger inbox.

**Note:** Only one Messenger DM can be sent per trigger.

### Step 4: Schedule & Launch

Review your settings and turn the bot on.

* **Timing:** Choose to Start Immediately or Schedule for later with a specific date and time.
* **Activate:** Click Activate Automation to go live.
