When building applications with Laravel, you’ll often work with APIs — whether it’s fetching user data, creating new records, or integrating with external services. But before your frontend or mobile app consumes those APIs, you need to test them properly.
That’s where Postman comes in.
Postman is a powerful tool that lets developers send requests to APIs and inspect their responses in an easy, visual way. In this article, we’ll walk through how to use Postman to test your Laravel APIs step by step.
Why Use Postman for API Testing?
- No extra code required — test your endpoints directly.
- Supports all HTTP methods (GET, POST, PUT, DELETE).
- Helps with debugging by showing headers, status codes, and responses.
- Organize endpoints in collections for quick access.
- Works with authentication (Bearer tokens, API keys, etc.).
Setting Up Laravel for API Testing
Before we dive into Postman, let’s get Laravel running locally.
- Start your Laravel app:
php artisan serve
- By default, it runs at:
http://127.0.0.1:8000
- or
http://localhost:8000
- Define your API routes inside
routes/api.php
. Example:
- Define your API routes inside
Route::get('/users', [UserController::class, 'index']);
Route::post('/users', [UserController::class, 'store']);
Installing and Opening Postman
- Download Postman 👉 https://www.postman.com/downloads
- Open the app.
- Create a New Request.
- Choose request type (
GET
,POST
, etc.). - Paste your Laravel API endpoint (e.g.,
http://localhost:8000/api/users
).
Sending Your First GET Request
- Select GET.
- Enter URL:
http://localhost:8000/api/users
- Click Send.
- You’ll see the JSON response from Laravel.
Sending a POST Request
- Select POST.
- Enter URL:
http://localhost:8000/api/users
- Go to Body → raw → JSON.
- Add sample data:
{
"name": "Rohit",
"email": "rohit@example.com"
}
- Click Send.
- You’ll get a response confirming that the user was created.
Debugging Tips
-
Check status codes:
- 200 = Success
- 201 = Created
- 404 = Not Found
- 500 = Server Error
Use Collections to save multiple requests for quick testing.
-
Add Authorization if routes are protected:
- In Postman, go to Authorization → Bearer Token.
- Paste your API token.
Wrap-Up
Postman is an essential tool for any Laravel developer working with APIs. It helps you:
✅ Quickly test endpoints
✅ Debug responses & errors
✅ Organize your API workflow
Start simple with GET and POST requests, then move on to PUT/DELETE and authentication.
By practicing with Postman, you’ll build more reliable APIs and save hours of debugging time.
