Test APIs with Postman

📌 What: Postman is a popular API testing tool that allows you to manually send GET, POST, PUT, and DELETE requests to your backend.

🎯 Why: Before connecting your frontend to the backend, it's essential to verify that your APIs work as expected. Postman provides an interface to test all aspects of an API — headers, body, params, etc.

⚙️ How: Open Postman and:

Select the HTTP method (e.g., GET, POST)
Enter the endpoint URL (e.g., http://localhost:5000/api/users)
Add any necessary headers like Content-Type: application/json
Include a request body for POST or PUT
Click "Send" and view the response

🕐 When: Use Postman every time you create or update an API route. It helps quickly detect issues with logic, validation, or data flow before moving to frontend integration.

        POST http://localhost:5000/api/register
        Headers:
          Content-Type: application/json

        Body (raw JSON):
        {
          "name": "John Doe",
          "email": "john@example.com",
          "password": "securePassword"
        }
      

💡 Tip: You can also save collections of APIs in Postman to test them repeatedly during development or share with your team.
