Needs changesNeeds changes. This template uses 1 thing(s) that n8n 3.0 removes: AI Agent v1 (old agent modes). 1 breaking item(s) found. Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 21 nodes and runs on Telegram events (message). Along the way it connects Telegram, OpenAI, OpenAI Chat Model and Postgres and 2 more.
How it runs
Trigger: On Telegram events (message).
- Voice or Text (Switch): routes items into 2 branches
- Download File (Telegram): work with file
- Text (Edit Fields (Set)): sets 1 field: text
- Transcribe (OpenAI): transcribe (audio)
- Scraper agent (AI Agent): runs an AI agent, with model: OpenAI Chat Model; memory: Simple Memory; output parser: Structured Output Parser
- Generate query payload (Edit Fields (Set)): sets or maps fields
- Select already scraped mails (Postgres): select
- Create URL (Code): runs custom JavaScript code
- Keep only the new leads (Compare Datasets): uses Compare Datasets
- Run an Actor (Apify): run actor
…plus 6 more steps. See the full node list below.
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 Scraper agent (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) Scraper agent (v1.9) | Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent. |
