Auto-Like Instagram Posts via n8n, Phantombuster & SharePoint

Automatically auto-like Instagram posts from specific profiles—using n8n, Phantombuster, and SharePoint

This n8n automation workflow schedules a regular check of Instagram profiles you track, selects recent posts, and triggers Phantombuster’s Autolike Agent to like them—while logging liked URLs in SharePoint to avoid duplicates. No manual scrolling required.

What this workflow does

• Runs on a schedule: the workflow is triggered every 2 hours.
• Extracts recent posts: a “Profile Post Extractor” pulls up to 20 recent posts from each Instagram profile listed in profiles_instagram.csv.
• Rotates Instagram session cookies: a “Select Cookie” step rotates session-cookies stored as instagram_session_cookies.txt.
• Chooses a random post & checks duplicates: “Get Random Post” selects a candidate and verifies it against instagram_posts_already_liked.csv (header: postUrl).
• Prepares SharePoint upload: builds instagram_posts_to_like.csv and uploads it to SharePoint.
• Likes via Phantombuster: the Phantombuster Autolike Agent performs the like action.
• Prevents re-liking: liked URLs are appended back to instagram_posts_already_liked.csv.
• Throttles activity: “Wait” nodes throttle actions to roughly 12 likes/profile/day.

Use cases

• Social-media managers keeping brand profiles active by auto-liking posts from a defined set of competitor or partner accounts.
• Growth hackers monitoring engagement signals from specific Instagram profiles—without manual browsing.
• SaaS operators running controlled engagement campaigns with centralized logging in Microsoft 365 SharePoint.
