Auto-Comment on Instagram Posts with GP-4O, Phantombuster, and SharePoint
## Who's it for
Social-media teams and influencers who want to grow engagement by automatically posting short, relevant comments on new Instagram posts under rotating hashtags while staying under platform limits.
## How it works / What it does
1. **Schedule Trigger** fires every 2h at a specified minute.
2. **Select Cookie** chooses a rotating Instagram session-cookie by time slice.
3. **Generate Random Hashtag** (GP-4o) outputs a realistic AI/BPA tag.
4. **Hashtag Agent** (Phantombuster) scrapes up to `ENV_MAX_POSS_PER_HASHAG` recent posts.
5. **Get Random Post** picks one; **Create Comment** (GP-4o) crafts a 150-character reply in the chosen language.
6. Builds `instagram_post_to_comment.csv`, uploads to SharePoint, then launches the **Auto-comment Agent** which posts the reply.
7. Post URL is logged to `instagram_posts_already_commented.csv` to avoid duplicates.
8. **Wait** nodes throttle launches to approximately 80 comments/day.
## 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_commented.csv` with header `postUrl`.
3. Edit **Set ENV Variables** to set default language, prompt, and max posts per scrape.
4. Activate the workflow; it will comment every 2h.
## Requirements
- n8n 1.33 +
- Phantombuster Growth plan (API access)
- OpenAI account (GP-4o)
- Microsoft 365 SharePoint tenant
## How to customize
- Change tone/length: tweak prompt in **Create Comment**.
- Comment more often: raise `ENV_MAX_POSS_PER_HASHAG`, adjust cron, and agent limits.
- Swap SharePoint for Drive/Dropbox by replacing storage nodes.
