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 for making a request and getting a response.\n\n\n**What is an Endpoint?**\nAn endpoint is a specific address for a specific action. For example, `GET /menu` is one endpoint to get the menu, and `POST /review` is another to submit a review. Each webhook in this tutorial represents one endpoint.\n\n**How to use this tutorial:**\n1.  **Activate** the workflow (toggle on the top right).\n2.  **Configure the Base URL** (see the yellow note to the left).\n3.  Click **\"Execute Workflow\"**. The workflow will run from top to bottom.\n4.  Explore each \"Lesson\" by clicking on the **HTTP Request** node (the Customer) and its corresponding **Webhook** node (the Kitchen).\n\n\n**➡️ How to See the Data:**\nWhen you run this, the Webhook nodes run in the background. To see the data they received, go to the **\"Executions\"** tab of this workflow. You will see a separate execution for each API call!",

We use an expression to get the Webhook's address automatically from our configuration.\n\n- **Method: `GET`**: This is **what you want to do**. `GET` is used to **retrieve** or **get** information. It's like asking the waiter, \"What's on the menu today?\" `GET` requests are simple and don't contain a \"body\" payload.\n\n\n**➡️ Look at the output of the HTTP Request node.

They are used to filter, sort, or specify what you want.\n\nIt's like telling the waiter, \"I'll have the pizza... **and can you add extra cheese?**\"\n\nThe full URL sent by the HTTP Request node looks like this:\n`.../tutorial/api/order?extra_cheese=true`\n\n**⚠️ Important:** Because they are part of the URL, **all query parameter values are treated as strings!** The webhook receives `\"true\"` (a string), not `true` (a boolean). The IF node is set to a \"loose\" comparison to handle this correctly.\n\n**➡️ The Webhook node uses an IF node to check for this parameter and changes its response. Try setting the value to `false` in the HTTP Request node and run it again!**",

Here, we use a custom header (`x-api-key`) as a \"secret key\". In the real world, this is how most APIs control access.\n\n\n**➡️ The Webhook checks for the correct secret key in the headers.

What if the kitchen is really busy?\n\n- **Timeout:** This is the **maximum amount of time (in milliseconds) you are willing to wait** for a response before you give up.\n\n- **On Error Output:** Notice the HTTP Request node has two outputs. The bottom one is the **error path**. If the request fails for any reason (like a timeout), the workflow will continue down this path instead of stopping.\n\n\nIn this example:\n- The **Kitchen (Webhook)** has a 3-second delay.\n- The **Customer (HTTP Request)** is only willing to wait for 2 seconds (2000 ms).\n\n\n**➡️ This request is designed to FAIL! The customer gives up before the kitchen can finish. The error output of the HTTP Request node will light up. This is crucial for building robust workflows that can handle API failures.**",
