API vs HTTP Request vs Webhook in n8n — What's the Difference? 🤔

Confused about when to use an API, HTTP Request, or Webhook in n8n? You're not alone! Here's a quick breakdown 👇

🔌 API (Application Programming Interface)

Think of it as a menu at a restaurant — it defines WHAT you can ask for and HOW. In n8n, when we say "use an API", we mean interacting with a service (like OpenAI or Notion) using its defined rules.

📡 HTTP Request Node

This is the actual waiter in n8n — it's the tool you use to SEND that request to an API. GET, POST, PUT, DELETE — it's how your workflow talks to the outside world.

👉 Use it when n8n doesn't have a native node for the service you need.

🪝 Webhook

A webhook is the reverse — instead of n8n asking for data, an EXTERNAL service pushes data TO your n8n workflow when something happens (e.g. a form is submitted, a payment is made).

👉 It's your workflow listening, not asking.

⚡ Quick Summary:

• API = The rules of communication

• HTTP Request = n8n sending a message

• Webhook = n8n receiving a message

Master these 3 concepts and you'll unlock 80% of what n8n can do! 🚀
