💡 Pro Tip — HTTP Request scraping tends to break when sites update their markup. If you’re scraping a major platform, check if ScraperNode covers it — it has maintained scrapers for LinkedIn, Instagram, TikTok, YouTube, and 20+ other platforms that return structured data.

Description

Who’s it for

Social-media managers and brands that want to keep their Instagram accounts active by automatically liking fresh posts under selected hashtags—hands-free and rate-limited.

How it works / What it does

1. Schedule Trigger runs every 2 hours at a specified minute.
2. Select Cookie chooses a rotating Instagram session-cookie (time-slice logic).
3. Generate Random Hashtag (GPT-4o) outputs a realistic AI/BPA hashtag.
4. Instagram Hashtag Agent (Phantombuster) scrapes up to ENV_MAX_POSTS_PER_HASHTAG recent posts.
5. Get Random Post selects one; duplicate checker ensures it hasn’t been liked before (SharePoint CSV).
6. Builds instagram_posts_to_like.csv, uploads to SharePoint, then launches the Auto-like Agent which likes the post.
7. Post URL is appended to instagram_posts_already_liked.csv to avoid duplicates.
8. Wait nodes throttle launches to ~12 likes per profile daily.

How to set up

1. Add credentials: Phantombuster API, SharePoint OAuth2, OpenAI API key.
2. In SharePoint › “Phantombuster” folder create:
   • instagram_session_cookies.txt – one cookie per line.
   • instagram_posts_already_liked.csv with header postUrl.
3. Adjust Set ENV Variables to change max posts per scrape.
4. Activate the workflow; it will like one post every 2 hours.
