Auto-reply to all new Facebook Page comments (as page comments, not replies) using ChatGPT and Data Store to prevent duplicates

Hi everyone :waving_hand:

I’ve built a scenario that does the following:

  1. Lists all posts from my Facebook Page

  2. Lists all user comments under those posts

  3. Sends each comment’s text to ChatGPT (OpenAI module) to generate a reply

  4. Posts the reply as a new comment on the post (not as a “reply to comment”)

It’s mostly working fine, but I want to improve it with a few key features:

:white_check_mark: Only reply once per comment, even if the scenario runs again later.
:white_check_mark: Save replied comment IDs in a Data Store (“Replied Comments”) to skip duplicates.
:white_check_mark: Reduce credit usage — currently it lists all posts and comments each time.
:white_check_mark: Eventually scale to multiple Facebook Pages (e.g. for different brands we manage).

I’d like to confirm:

  1. The best practice for the Data Store + Filter setup so it doesn’t re-reply.

  2. The correct logic to ensure ChatGPT’s response posts directly on the post (not nested as a reply).

  3. Any optimisation tips for large pages with many posts/comments.

If anyone has an example blueprint, screenshots, or step-by-step advice for this “Facebook Comments + ChatGPT + Data Store” workflow, I’d really appreciate it :folded_hands:

Thank you!
