Trigger: When an HTTP GET request hits its webhook URL (plus 3 other triggers).
- RenameInputFields (Edit Fields (Set)): sets or maps fields
- HTTP Request: calls an HTTP API
- Set Lead Variables (Edit Fields (Set)): sets or maps fields
- ValidateMessageExists (If): checks a condition and branches into true / false
- Information Extractor: extracts structured fields from text with AI, with model: OpenAI Chat Model
- Generate Intro Message (Function): runs custom JavaScript (legacy Function node)
- CleanUserText (Code): runs custom JavaScript code
- AI Agent: runs an AI agent, with model: OpenAI Chat Model; 2 tools (SerpAPI, Calculator)
- ElevenLabs - Generate Voice (HTTP Request): calls an HTTP API
- ClassifyIntentUrgency (AI Agent): runs an AI agent, with model: OpenAI Chat Model
…plus 21 more steps. See the full node list below.

Before you upgrade to n8n 3.0
3 things in this workflow are removed in n8n 3.0. Fix them before you upgrade:
- AI Agent v1 (old agent modes) in ClassifyIntentUrgency (v1), AI Agent (v1.9), AI Agent - Extract Lead Info (v1)…: replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
- SerpApi (Google Search) in SerpAPI: no direct replacement: call the SerpApi REST API with an HTTP Request tool, or use a verified community node.
- Function (legacy) in Generate Intro Message, Store Extracted Values, Assign Lead Score: replace with Code node, mode 'Run Once for All Items'.
