⚡ 584 views · 📱 Social Media & Email Marketing

💡 Pro Tip — Heads up — if this workflow’s Instagram scraping breaks (it happens whenever Meta updates their frontend), ScraperNode is a community node that handles profiles, posts, reels, and comments without any HTML parsing.

Description

Who’s it for

Influencers and social-media teams who want to comment automatically on posts from selected Instagram profiles—scaling engagement while staying within platform limits.

How it works / What it does

1. Schedule Trigger runs every 2 h.
2. Profile Post Extractor fetches up to 20 posts per profile from your CSV.
3. Select Cookie rotates Instagram session-cookies.
4. Get Random Post selects one.
5. Create Comment (GPT-4o) writes ≤150-character reply in your chosen language.
6. Builds instagram_post_to_comment.csv, uploads to SharePoint.
7. Phantombuster Autocomment Agent posts it.
8. Logged in instagram_posts_already_commented.csv to prevent repeats.

How to set up

• Same as the auto-liker, but also add instagram_posts_already_commented.csv (header postUrl).
• Define tracked profiles in profiles_instagram.csv.
• Configure comment prompt & language in Set ENV Variables.

Profile CSV format

Your profiles_instagram.csv must contain a header profileUrl and valid Instagram profile URLs. Example:

profileUrl
https://www.instagram.com/brand_account/
https://www.instagram.com/influencer123/
