Monitor Facebook post safety with Apify and Gemini: n8n workflow

Monitor Facebook post safety with Apify and Gemini

Started by an incoming Telegram message, and works across Apify, Telegram and n8n data table. It puts Gemini behind a retrieval step, so answers are drawn from documents you supply rather than from the model alone. 28 steps: large, and worth reading before you trust it with anything live.

Questions

What does it need to run?

An n8n account, plus your own Apify and Telegram accounts, and a key for Gemini. You connect your own accounts after importing it; none are included.

What starts it?

It starts on an incoming Telegram message.

Does it use AI?

Yes. It calls Gemini. Its answers draw on documents you give it, not on the model alone. Model calls are billed by the provider, not by n8n.

How long does it take to set up?

Take your time. At 28 steps it is large: read it before trusting it with anything live.

How do I import it?

Copy the workflow, open a new workflow in n8n and paste. The steps appear on the canvas, ready for your own accounts.

Before you run it

Nothing here has been tested by us. It is somebody's working automation, read and described from its own steps. Treat the connections it wants as a list of accounts it will touch, and read the 28 steps before you point it at anything that matters.
