My Instagram business account needs to be fully connected to n8n so every new Direct Message or Comment triggers an automated acknowledgement. I want roughly four to seven short acknowledgement templates rotating to keep the replies from sounding repetitive. Here’s the flow I need built: 1. Authenticate the Instagram Graph API inside n8n. 2. Detect incoming DMs and public comment events in real time (webhook or efficient polling). 3. Pick one acknowledgement template at random and post it back in the same thread or comment chain. 4. Log each interaction inside n8n for quick auditing and future analytics. Deliverables: an exportable n8n workflow (.json) and concise setup notes so I can add or edit templates later and expand to mentions if required. Acceptance criteria: workflow imports cleanly in the current n8n version, replies appear within 30 seconds during testing, and template rotation is clearly visible for both DMs and comments.
