Use AI to Auto-Reply to Facebook and Instagram Comments in GoHighLevel

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.

It covers which trigger variable to use to capture the comment text, how to pass it into a GPT workflow action with a custom prompt, and how to route the GPT output back as a posted comment reply. The same pattern also works for direct messages.
