This page: https://commentwatchdog.com/help/flow-starts/start-a-flow-from-comments-on-your-ads

Topic: Flow starts

Time: about 3 minutes

Who can do it: Owner, Administrator or Manager

Author: https://anantgupta.xyz (Anant Gupta, founder of CommentWatchDog)

Start in the app: https://app.commentwatchdog.com/en/inbox

Result when done: Comments under your Facebook and Instagram ads get the flow.

Context: The same comment start, narrowed to your ads. Meta sends comments on ad posts to CommentWatchDog like any other comment (Instagram's carry the ad they were left on), so a flow can answer the person who asked under your ad with the one private reply Meta allows, while the ad keeps running.

Before you start

1. Ads only is a choice of the comment start, on Instagram and Facebook.

2. Meta allows one private reply per comment, within 7 days of it.

3. Facebook cannot send a private reply to another Page.

Steps

If something is off

Problem: A commenter never got the private reply

Fix: On Instagram a private reply to someone who does not follow you lands in their Requests folder. On Facebook, a comment left by another Page cannot get one.

Problem: Old ad comments did not get it

Fix: The private reply must go within 7 days of the comment. A flow answers comments that arrive while it is live.

Common questions

Question: Does it work on Instagram ads too?

Answer: Yes. Ads only is a choice of the comment start on both Instagram and Facebook; Instagram's comment events carry the ad they were left on.

Question: Can the flow answer the same comment twice in private?

Answer: No. Meta allows one private reply per comment, and the canvas refuses a second. Anything more goes after the person taps or replies.

Question: Can I pick one ad instead of all of them?

Answer: Yes. Pick posts holds the posts and ads you choose; paste an ad's post link to find one that is not in the list.
