🛠 API Testing and Debugging

🔐 Authentication Setup

Before making requests, define your OAuth token or Bearer token.

1️⃣ Get OAuth 2.0 Token (if required)

Use this step only if your API requires OAuth 2.0 client credentials flow.

const authResponse = await fetch("https://auth.example.com/token", {
  method: "POST",
  headers: { "Content-Type": "application/x-www-form-urlencoded" },
  body: new URLSearchParams({
    grant_type: "client_credentials",
    client_id: "your_client_id",
    client_secret: "your_client_secret"
  })
});
const { access_token } = await authResponse.json();
console.log("OAuth Token:", access_token);

---

2️⃣ Define API Base URL & Authentication

Set your API base URL and token (replace with your actual values).

const baseURL = "https://api.example.com"; 
const token = "your_api_token_here"; // Replace with OAuth token if using OAuth

🔍 API Requests

📥 GET - Fetch Data

Retrieve user information.

const response = await fetch(`${baseURL}/users`, {
  method: "GET",
  headers: { "Authorization": `Bearer ${token}` }
});
console.log(await response.json());

---

📤 POST - Add a New User

Create a new user in the system.

const response = await fetch(`${baseURL}/users`, {
  method: "POST",
  headers: { "Content-Type": "application/json", "Authorization": `Bearer ${token}` },
  body: JSON.stringify({ name: "John Doe", email: "john@example.com" })
});
console.log(await response.json());

---

✏️ PUT - Update an Existing User

Modify an existing user by ID.

const response = await fetch(`${baseURL}/users/123`, {
  method: "PUT",
  headers: { "Content-Type": "application/json", "Authorization": `Bearer ${token}` },
  body: JSON.stringify({ name: "Jane Doe" })
});
console.log(await response.json());

---

🗑️ DELETE - Remove a User

const response = await fetch(`${baseURL}/users/123`, { 
  method: "DELETE", 
  headers: { "Authorization": `Bearer ${token}` } 
});
console.log(await response.json());

⚡ Debugging with AI Assistance

❓ Issue with the request? Ask Znote AI:

"Why is my API call failing?"

💡 Pro Tips:

• Ensure your base URL matches the correct API environment (staging, production, etc.).
• Some APIs require additional headers, such as "Accept": "application/json".
• Use OAuth 2.0 flow if the API doesn’t accept static tokens.
