What this workflow does
This AI workflow has 12 nodes and runs when someone submits an n8n form (“Lecture to WhatsApp Digest”). Along the way it connects OpenAI Chat Model and Google Sheets. It also calls wayinvideo-api.wayin.ai over HTTP.
How it runs
Trigger: When someone submits an n8n form (“Lecture to WhatsApp Digest”).

- 3. HTTP — WayinVideo Submit Summarization (HTTP Request): calls wayinvideo-api.wayin.ai (POST)
- 4. Wait — 90 Seconds (Wait): waits 90 seconds
- 5. HTTP — WayinVideo Get Summary Results (HTTP Request): calls an HTTP API
- 6. IF — Summary Ready? (If): checks a condition and branches into true / false
- 8. AI Agent — Generate Study Digest (AI Agent): runs an AI agent, with model: OpenAI — GPT-4o-mini Model
- 7. Wait — 30 Second Retry (Wait): waits 30 seconds

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 8. AI Agent — Generate Study Digest (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).
