Use AI to Auto-Reply to Facebook and Instagram Comments in GoHighLevel
By Marnix Geerkens. Published 2024-04-04. Updated 2026-06-02.
GoHighLevel workflows can pass Facebook and Instagram comment text to a GPT action, generate a reply, and post that reply back to the comment thread automatically. The key is using the correct variable, such as the comment body field from the social trigger, as the input to the GPT step. The generated response can then be piped back as the comment reply without any manual work.
