This workflow will teach you the basics of APIs (Application Programming Interfaces).\n\n**What is an API?**\nThink of it like ordering food at a restaurant.\n- **You** are the \"Client\" (the **HTTP Request** node). You want something.\n- The **Kitchen** is the \"Server\" (the **Webhook** node). It has the data/service you want.\n- The **API** is the **Waiter and the Menu**. It's the set of rules and options you have for making a request and getting a response.\n\n\n**How to use this tutorial:**\n1. Click **\"Execute Workflow\"**. The workflow will run from top to bottom.\n2. Explore each \"Lesson\" by clicking on the **HTTP Request** node (the Customer) and its corresponding **Webhook** node (the Kitchen).\n3. Read the sticky note for each lesson to understand the concept being demonstrated."

The HTTP Request node needs to know exactly where to send the order. We use a special n8n expression to get the Webhook's test address automatically.\n\n- **Method: `GET`**: This is **what you want to do**. `GET` means you simply want to **retrieve** or **get** information. It's like asking the waiter, \"What's on the menu today?\"\n\n\n**➡️ Look at the output of the HTTP Request node. It received exactly what the Webhook is configured to listen to!**"

It's information that proves who you are or what your request's properties are.\n\n- **Authentication (Auth):** This is the process of proving your identity. Here, we use a custom header (`x-auth-token`) as a \"secret key\".\n\n\n**➡️ The Webhook checks for the correct secret key in the headers. If it's wrong or missing, it denies the request!**"
