Question

Is the post ID available as a variable in a comment-triggered flow?

Hi everyone,

I am building an Instagram comment automation: one automation, triggered on any
post or reel, with a list of keywords. When someone comments, I want the flow to
call my own server with "Make an external request" and get back a link that
depends on which reel was commented on, because each reel offers a different
resource.

Two questions:

1. Is the ID of the post or reel that triggered the flow available as a variable
   that I can include in the external request?

2. Is the text of the comment available the same way?

Thanks a lot.

Hi, ​@Anthony 56860!

 

Unfortunately, Manychat does not provide the post ID or the comment text as native system variables to be used in standard flows...

 

The only way to achieve this setup is to create a specific comment-triggered automation for each post or reel you want to run this on. In each of these individual triggers, you can set a Custom User Field with the specific information about that origin post, which you can then pass along in your external request. But that only covers the origin of the trigger, not the text of the comment.

 

And if the flow itself is long or complex, a good practice to simplify maintenance is to keep the trigger automation very short:

  1. Set up the trigger for the specific post.

  2. Add an Action block to set the Custom User Field with that post's information.

  3. Use a "Start Automation" step to direct the flow to your main, central automation where the rest of the logic and external request take place.

It will look something like this:

 

This way, if you need to make changes to your main server request or logic in the future, you only have to edit one single flow instead of updating every post automation.

 

Hope this helps!
