What this workflow does
This AI workflow has 13 nodes and runs when an HTTP POST request hits its webhook URL (plus 1 other trigger). Along the way it connects OpenAI Chat Model, Pinecone Vector Store and Embeddings OpenAI.
How it runs
Trigger: When an HTTP POST request hits its webhook URL (plus 1 other trigger).
- AI Agent: runs an AI agent, with model: LLM Model; 1 tool (Manual Knowledge Base); memory: Conversation Memory
- Prepare Manual Data (Edit Fields (Set)): sets 2 fields: deviceType, text
- Send Response (Respond to Webhook): sends the response back to the webhook caller
- Upload to Vector Database (Pinecone Vector Store): stores documents in the Pinecone vector store, with embeddings: Upload Embeddings; document loader: Document Loader
Services it uses
Before you upgrade to n8n 3.0
1 thing in this workflow is removed in n8n 3.0. Fix it before you upgrade:
- AI Agent v1 (old agent modes) in AI Agent - Device Expert (v1.9): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
| Removed in 3.0 | Replace with |
|---|---|
| AI Agent v1 (old agent modes) AI Agent - Device Expert (v1.9) | Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent. |
