Scheduled Instagram auto-liker with Phantombuster, GPT-4o & cookie rotation

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 ENVMAXPOSTSPERHASHTAG recent posts. 5. Get Random Post selects one; duplicate checker ensures it hasn’t been liked before (SharePoint CSV). 6. Builds instagrampoststolike.csv, uploads to SharePoint, then launches the Auto-like Agent which likes the post. 7. Post URL is appended to instagrampostsalreadyliked.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: • instagramsessioncookies.txt – one cookie per line. • instagrampostsalreadyliked.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.
