This n8n workflow streamlines engagement on Instagram by automatically monitoring comments on a specific post or reel, filtering out those already responded to, and sending personalized direct message replies. It uses a combination of Google Sheets to track contacted users, HTTP requests to interact with Instagram comments and DMs, and a scheduled trigger to run every 15 minutes. When new comments are detected, the workflow checks against previous responses, posts DMs to new commenters, and logs interactions in Google Sheets. Additionally, it generates a summary report of the session, including total comments, new comments, and reply success, helping manage Instagram engagement efficiently.
