Summary
Wati's automation rules let you automatically reply to Facebook comments and send a direct message (DM) through Messenger when a comment matches specified keywords. You can apply the rule to all connected Facebook posts and reels or to a specific post or reel. This helps you engage with commenters and respond to relevant comments automatically.
Instructions
Before you begin
Make sure your Facebook Page is connected to your Wati account. To verify the connection, go to Settings > Channels in Wati.
Set up Facebook comment-to-DM automation
Step 1: Create a new rule
Log in to Wati and go to Automation > Rules.
Click + New Rule.
Step 2: Select the trigger
Under Facebook Triggers, select New Facebook comment is received.
Choose which posts or reels the rule should monitor:
All posts and reels: Apply the rule to all posts and reels connected to your Facebook Page.
Specific post or reel: Apply the rule only to a selected post or reel.
The rule runs when someone adds a new comment to a post or reel within the selected scope.
Step 3: Add a keyword condition
Under Select your criteria, select Comment matches keyword rule.
Choose how the system should match keywords in incoming comments:
Fuzzy matching: Matches similar words and variations, including minor spelling mistakes.
Exactly matches: Triggers the rule only when the comment matches the specified keyword exactly.
Contains: Triggers the rule when the comment contains the specified keyword anywhere in the message.
Enter the keywords you want the rule to detect.
Add multiple keywords if needed, or create separate rules for different keywords.
The rule triggers only when a new comment meets the configured keyword condition.
Step 4: Configure the action
Set the action to Send DM.
Set Message Type to Text.
Select a text message from the Reply Material Library.
To create a new text message, click Create new message and configure the message as needed.

When this option is enabled, Wati sends the configured message as a DM and posts a reply to the comment.
Step 5: Save and activate the rule
Enter a name for the rule.
Click Save Changes.
Switch on the rule to activate it.
