Flutter REST API Integration

bookAPI Testing with Postman and cURL

Before connecting your Flutter app to a REST API, it is crucial to make sure the API works as expected. Tools like Postman and cURL allow you to test and explore endpoints directly, so you can confirm they return the correct status codes and data formats. This helps you avoid surprises and wasted time when you start writing Dart code.

# Send a GET request to fetch user data from a sample API curl -i https://jsonplaceholder.typicode.com/users/1

When you run the cURL command, you will see output in your terminal that includes the HTTP status code, headers, and the body of the response. Check that the status code is 200 OK and that the JSON data matches what your Flutter app will expect. If the data or status is wrong, you can address the issue before writing any integration code.

Testing APIs with Postman or cURL helps you catch problems like incorrect endpoints, missing fields, or unexpected errors before you start integrating the API into your Flutter application. This saves development time and reduces debugging headaches later.
