Share on:

Yudhy Network - Laravel 8 jwt authentication example. In this tutorial, you will learn how to build rest api using jwt auth in laravel 8 app.

Laravel 8 JWT API authentication example. In this tutorial, you will learn how to build the rest APIs with jwt (JSON web token) authentication in laravel 8.

As well as will show you how to install jwt auth and configure jwt auth in laravel 8 app.

First of all, you need to know the following things about API:

  • What is API?
  • what is the use of APIs in laravel?

What is API?

API is the acronym for Application Programming Interface, which is a software intermediary that allows two applications to talk to each other. Each time you use an app like Facebook, send an instant message or check the weather on your phone, you’re using an API.

What is the use of API in laravel?

APIs typically use tokens to authenticate users and do not maintain session state between requests. Laravel makes API authentication a breeze using Laravel jwt, which provides a full OAuth2 server implementation for your Laravel application development in a matter of minutes.

So, in this tutorial, you will learn step by step how to create rest API with laravel 8 jwt authentication. And as well as how to install and cofigure jwt auth in laravel 8 app.

  • Step 1: Download Laravel 8 App
  • Step 2: Database Configuration
  • Step 3: Install JWT Auth
  • Step 4: Registering Middleware
  • Step 5: Run Migration
  • Step 6: Create APIs Route
  • Step 7: Create JWT Auth Controller
  • Step 8: Now Test Laravel REST API in Postman

Step 1: Download Laravel 8 App

First of all, Open command prompt and run the following command to install laravel 8 app:

composer create-project --prefer-dist laravel/laravel blog

Step 2: Database Configuration

Then, Navigate root directory of your installed laravel restful authentication api with jwt tutorial project. And open .env file. Then add the database details as follow:

 DB_DATABASE=here your database name here
 DB_USERNAME=here database username here
 DB_PASSWORD=here database password here

Step 3: Install JWT Auth

In this step, run the below command and install composer require tymon/jwt-auth package :

composer require tymon/jwt-auth

After successfully install laravel jwt, register providers. Open config/app.php . and put the bellow code :

  // config/app.php

'providers' => [
'aliases' => [
'JWTAuth' => 'Tymon\JWTAuth\Facades\JWTAuth',
'JWTFactory' => 'Tymon\JWTAuth\Facades\JWTFactory',

Now, you need to install laravel to generate jwt encryption keys. This command will create the encryption keys needed to generate secure access tokens:

php artisan jwt:generate

then open JWTGenerateCommand.php file and paste this following code, Hope it will work.


public function handle() {


Step 4: Registering Middleware

JWT auth package comes up with middlewares that we can use. Register auth.jwt middleware in 


protected $routeMiddleware = [

    'auth.jwt' => 'auth.jwt' => 'Tymon\JWTAuth\Middleware\GetUserFromToken',


Step 5: Run Migration

In this step, you need to do migration using the bellow command. This command creates tables in the database :

php artisan migrate

Step 6: Create APIs Route

In this step, you need to create rest API routes for laravel restful authentication apis with jwt project.

So, navigate to the routes directory and open api.php. Then update the following routes into api.php file:

use App\Http\Controllers\API\JWTAuthController;

Route::post('register', [JWTAuthController::class, 'register']);
Route::post('login', [JWTAuthController::class, 'login']);
Route::group(['middleware' => 'auth.jwt'], function () {

    Route::post('logout', [JWTAuthController::class, 'logout']);

Step 7: Create JWT Auth Controller

In this step, you need to create a controller name JWTAuthController. Use the below command and create a controller :

 php artisan make:controller Api\JWTAuthController

After that, you need to create some methods in JWTAuthController.php. So navigate to app/http/controllers/API directory and open JWTAuthController.php file. After that, update the following methods into your JWTAuthController.php file:


namespace App\Http\Controllers\API;

use JWTAuth;
use Validator;
use App\Models\User;
use Illuminate\Http\Request;
use Tymon\JWTAuth\Exceptions\JWTException;
use Symfony\Component\HttpFoundation\Response;

class JwtAuthController extends Controller
    public $token = true;
    public function register(Request $request)

         $validator = Validator::make($request->all(), 
                      'name' => 'required',
                      'email' => 'required|email',
                      'password' => 'required',  
                      'c_password' => 'required|same:password', 

         if ($validator->fails()) {  

               return response()->json(['error'=>$validator->errors()], 401); 


        $user = new User();
        $user->name = $request->name;
        $user->email = $request->email;
        $user->password = bcrypt($request->password);
        if ($this->token) {
            return $this->login($request);
        return response()->json([
            'success' => true,
            'data' => $user
        ], Response::HTTP_OK);
    public function login(Request $request)
        $input = $request->only('email', 'password');
        $jwt_token = null;
        if (!$jwt_token = JWTAuth::attempt($input)) {
            return response()->json([
                'success' => false,
                'message' => 'Invalid Email or Password',
            ], Response::HTTP_UNAUTHORIZED);
        return response()->json([
            'success' => true,
            'token' => $jwt_token,
    public function logout(Request $request)
        $this->validate($request, [
            'token' => 'required'
        try {
            return response()->json([
                'success' => true,
                'message' => 'User logged out successfully'
        } catch (JWTException $exception) {
            return response()->json([
                'success' => false,
                'message' => 'Sorry, the user cannot be logged out'
            ], Response::HTTP_INTERNAL_SERVER_ERROR);
    public function getUser(Request $request)
        $this->validate($request, [
            'token' => 'required'
        $user = JWTAuth::authenticate($request->token);
        return response()->json(['user' => $user]);

Then open command prompt and run the following command to start developement server:

 php artisan serve

Step 8: Now Test Laravel REST API in Postman

Here, you can see that, how to call laravel 8 restful API with jwt authentication:

Laravel Register Rest API :

laravel register api
laravel register api

Login API :

laravel passport login api
laravel login api

Next Step, you will call getUser API, In this API you have to set two headers follows:

Call login or register apis put $accessToken.

‘headers’ => [
‘Accept’ => ‘application/json’,
‘Authorization’ => ‘Bearer ‘.$accessToken,


Pass header in login/register rest API. it is necessary to jwt authentication in laravel app
