# AI sales agent: WhatsApp, FB, IG, OpenAI, Airtable, Supabase

Started by an incoming WhatsApp message, and works across Airtable, Supabase vectors and WhatsApp. It puts OpenAI behind a retrieval step, so answers are drawn from documents you supply rather than from the model alone. 50 steps, 4 branches: large, and worth reading before you trust it with anything live.

## Questions

What does it need to run?

An n8n account, plus your own Airtable, Supabase vectors and WhatsApp accounts, and a key for OpenAI. You connect your own accounts after importing it; none are included.

What starts it?

It starts on an incoming WhatsApp message.

Does it use AI?

Yes. It calls OpenAI. 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 50 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 50 steps before you point it at anything that matters.
