Auto Inbox
Step 1: Get the Post ID on the Fanpage
To set up comment keywords for each specific post, you need to get the Post ID of the post on the Fanpage and paste it into the Auto Inbox tool of AhaChat.
To get the Post ID of the post, follow these instructions:
1.1 Comment on the POST from which you need to get the ID
1.2 Go to Livechat → Filter by Comment → Copy the link of the post
1.3 Go to the Growth menu → create a new Auto Inbox → Select a specific post and paste the link here
Step 2: Create Auto Inbox at Growth menu
It is noted that you can choose auto-inbox for all posts or a specific post
In particular, the auto-reply feature could be marked as spam because you use only one Facebook account to reply comments continuously in a short period of time. This makes your account susceptible to blocking by Facebook. If you use the said account frequently, the account could be blocked for one (1) whole month. Therefore, you have to invite at least 3 secondary accounts to become the editor or admin page so that comments could be replied by different accounts. Each secondary account will reply 20 comments within 1 minute. And so, if you have 60 comments per minute, you need at least 3 secondary accounts. (this formula is used to calculate the minimum number of secondary accounts used for this feature).
You have to click on the Agree blue button, then you will be directed to Settings > Role. You must click +Invite button and copy the last link
After invited successfully, you will see the interface like below
If there are red triangles, this means that account has failed, you should click on this icon to determine following causes:
- This account is restricted from the like and comment features. You have to add another account to replace or wait until Facebook unlocks. The error notification is “You’re temporarily restricted from liking posts, Pages and comments, and from reviewing Pages…”
- This account has an error token, you have to log out and log in AhaChat. After that, please hit Refresh permissions so that feature could run normally again. The error notification is “Error validating access token the user has not authorized application…”
- This account was added on AhaChat but it has removed permission as Editor or Admin on fanpage. You have to add these permissions again on Fanpage. This error notification is “Permission error…”
After 3 sub accounts are invited, reply-comment feature is opened to fill content as the following
Finally, create contents of the inbox. Spintax {hi|hello|welcome} is recommended to use so that the message will not be marked as spam.
Step 3: Testing
You have to enter a comment on a post to confirm whether this feature is set up successfully. It is noted that you have to use a personal account to comment and you may wait more than 1 minute to receive the auto message.
- Customers who reply to Auto-Inbox will become a bot subscriber.
- Only auto reply for Personal account, not Page account.
- Time of auto reply could be delayed about 1 minute
- Spintax and {{full_name}} are recommended to use
- If Auto-Inbox cannot work, please refer to the cause.
Process Missed Comments
The Process Missed Comments feature allows AhaChat to retroactively scan comments on your post from the last 7 days and process them through the configured Auto Inbox flow.
When to use:
- When applying an Auto Inbox rule to an existing post that already has prior comments.
- When the bot connection was temporarily interrupted or disabled, causing some comments to be missed.
How to use:
- In the Growth section under the Auto Inbox list, click the settings gear icon (⚙️) next to the target campaign.
- Select Process Missed Comments from the dropdown menu.

- A confirmation modal will appear with the message:
"Scan this post's comments from the last 7 days and run them through this auto inbox. Comments already handled will be skipped. This sends real replies and private messages."
- Click Process to start scanning and triggering automated responses for any unhandled comments.

Note: Comments that have already been handled will automatically be skipped to prevent duplicate messages from being sent to customers.
