Description
How it works
This beginner-friendly workflow demonstrates the core building blocks of n8n. It guides you through:
- Triggers – Start workflows manually, on a schedule, via webhooks, or through chat.
- Data processing – Use Set and Code nodes to create, transform, and enrich data.
- Logic and branching – Apply conditions with IF nodes and merge different branches back together.
- API integrations – Fetch external data (e.g., users from an API), split arrays into individual items, and extract useful fields.
- AI-powered steps – Connect to OpenAI for generating fun facts or build interactive assistants with chat triggers, memory, and tools.
- Responses – Return structured results via webhooks or summary nodes.
By the end, it demonstrates a full flow: creating data → transforming it → making decisions → calling APIs → using AI → responding with outputs.
Set up steps
Time required: 5–10 minutes.
-
What you need:
- An n8n instance (cloud or self-hosted).
- Optional: API credentials (e.g., OpenAI) if you want to test AI features.
-
Setup flow:
- Import this workflow.
- Add your API keys where needed (OpenAI, etc.).
- Trigger the workflow manually or test with webhooks.
>👉 Detailed node explanations and examples are already included as sticky notes inside the workflow itself, so you can learn step by step as you explore.
