Laravel 10 REST API with Passport Authentication Tutorial

Passport allows you to implement token-based authentication, where clients authenticate with an access token instead of sending credentials with each request. This adds an extra layer of security to your API as sensitive information like passwords is not transmitted with every request.

Step 1: Install Laravel App

composer create-project laravel/laravel example-pagination

Step 2: Install Passport

composer require laravel/passport

Run default migration command:

php artisan migrate

create token keys for security. So let's run bellow command:

php artisan passport:install

Step 3: Passport Configuration

In model we added HasApiTokens class of Passport,

app/Models/User.php 

<?php
  
    namespace App\Models;
      
    use Illuminate\Contracts\Auth\MustVerifyEmail;
    use Illuminate\Database\Eloquent\Factories\HasFactory;
    use Illuminate\Foundation\Auth\User as Authenticatable;
    use Illuminate\Notifications\Notifiable;
    use Laravel\Passport\HasApiTokens;
      
    class User extends Authenticatable
    {
        use HasApiTokens, HasFactory, Notifiable;
      
        /**
         * The attributes that are mass assignable.
         *
         * @var array
    
         */
        protected $fillable = [
            'name',
            'email',
            'password',
        ];
      
        /**
         * The attributes that should be hidden for serialization.
         *
         * @var array
    
         */
        protected $hidden = [
            'password',
            'remember_token',
        ];
     
        /**
         * The attributes that should be cast.
         *
         * @var array
    
         */
        protected $casts = [
            'email_verified_at' => 'datetime',
        ];
    }

config/auth.php

<?php


    return [
        .....
        'guards' => [
            'web' => [
                'driver' => 'session',
                'provider' => 'users',
            ],
            'api' => [
                'driver' => 'passport',
                'provider' => 'users',
            ],
        ],
        .....
    ]
    
    

Step 4: Add Table and Model

php artisan make:migration create_products_table

database/migrations and you have to put bellow code in your migration file for create products table.

<?php
  
    use Illuminate\Database\Migrations\Migration;
    use Illuminate\Database\Schema\Blueprint;
    use Illuminate\Support\Facades\Schema;
      
    return new class extends Migration
    {
        /**
         * Run the migrations.
         *
         * @return void
         */
        public function up(): void
        {
            Schema::create('products', function (Blueprint $table) {
                $table->id();
                $table->string('name');
                $table->text('detail');
                $table->timestamps();
            });
        }
      
        /**
         * Reverse the migrations.
         *
         * @return void
         */
        public function down(): void
        {
            Schema::dropIfExists('products');
        }
    };

app/Models/Product.php

<?php
  
    namespace App\Models;
      
    use Illuminate\Database\Eloquent\Factories\HasFactory;
    use Illuminate\Database\Eloquent\Model;
      
    class Product extends Model
    {
        use HasFactory;
      
        /**
         * The attributes that are mass assignable.
         *
         * @var array
         */
        protected $fillable = [
            'name', 'detail'
        ];
    }
    

Step 5: Create API Routes

routes/api.php 

<?php
  
  use Illuminate\Http\Request;
  use Illuminate\Support\Facades\Route;
    
  use App\Http\Controllers\API\RegisterController;
  use App\Http\Controllers\API\ProductController;
    
  /*
  |--------------------------------------------------------------------------
  | API Routes
  |--------------------------------------------------------------------------
  |
  | Here is where you can register API routes for your application. These
  | routes are loaded by the RouteServiceProvider within a group which
  | is assigned the "api" middleware group. Enjoy building your API!
  |
  */
    
  Route::post('register', [RegisterController::class, 'register']);
  Route::post('login', [RegisterController::class, 'login']);
       
  Route::middleware('auth:api')->group( function () {
      Route::resource('products', ProductController::class);
  });

Step 6: Create Controller Files

app/Http/Controllers/API/BaseController.php 

<?php


    namespace App\Http\Controllers\API;
    
    
    use Illuminate\Http\Request;
    use App\Http\Controllers\Controller as Controller;
    
    
    class BaseController extends Controller
    {
        /**
         * success response method.
         *
         * @return \Illuminate\Http\Response
         */
        public function sendResponse($result, $message)
        {
            $response = [
                'success' => true,
                'data'    => $result,
                'message' => $message,
            ];
    
    
            return response()->json($response, 200);
        }
    
    
        /**
         * return error response.
         *
         * @return \Illuminate\Http\Response
         */
        public function sendError($error, $errorMessages = [], $code = 404)
        {
            $response = [
                'success' => false,
                'message' => $error,
            ];
    
    
            if(!empty($errorMessages)){
                $response['data'] = $errorMessages;
            }
    
    
            return response()->json($response, $code);
        }
    }

app/Http/Controllers/API/RegisterController.php

<?php
     
    namespace App\Http\Controllers\API;
         
    use Illuminate\Http\Request;
    use App\Http\Controllers\API\BaseController as BaseController;
    use App\Models\User;
    use Illuminate\Support\Facades\Auth;
    use Validator;
    use Illuminate\Http\JsonResponse;
         
    class RegisterController extends BaseController
    {
        /**
         * Register api
         *
         * @return \Illuminate\Http\Response
         */
        public function register(Request $request): JsonResponse
        {
            $validator = Validator::make($request->all(), [
                'name' => 'required',
                'email' => 'required|email',
                'password' => 'required',
                'c_password' => 'required|same:password',
            ]);
         
            if($validator->fails()){
                return $this->sendError('Validation Error.', $validator->errors());       
            }
         
            $input = $request->all();
            $input['password'] = bcrypt($input['password']);
            $user = User::create($input);
            $success['token'] =  $user->createToken('MyApp')->accessToken;
            $success['name'] =  $user->name;
       
            return $this->sendResponse($success, 'User register successfully.');
        }
         
        /**
         * Login api
         *
         * @return \Illuminate\Http\Response
         */
        public function login(Request $request): JsonResponse
        {
            if(Auth::attempt(['email' => $request->email, 'password' => $request->password])){ 
                $user = Auth::user(); 
                $success['token'] =  $user->createToken('MyApp')-> accessToken; 
                $success['name'] =  $user->name;
       
                return $this->sendResponse($success, 'User login successfully.');
            } 
            else{ 
                return $this->sendError('Unauthorised.', ['error'=>'Unauthorised']);
            } 
        }
    }

app/Http/Controllers/API/ProductController.php

<?php
       
    namespace App\Http\Controllers\API;
           
    use Illuminate\Http\Request;
    use App\Http\Controllers\API\BaseController as BaseController;
    use App\Models\Product;
    use Validator;
    use App\Http\Resources\ProductResource;
    use Illuminate\Http\JsonResponse;
           
    class ProductController extends BaseController
    {
        /**
         * Display a listing of the resource.
         *
         * @return \Illuminate\Http\Response
         */
        public function index(): JsonResponse
        {
            $products = Product::all();
            
            return $this->sendResponse(ProductResource::collection($products), 'Products retrieved successfully.');
        }
        /**
         * Store a newly created resource in storage.
         *
         * @param  \Illuminate\Http\Request  $request
         * @return \Illuminate\Http\Response
         */
        public function store(Request $request): JsonResponse
        {
            $input = $request->all();
           
            $validator = Validator::make($input, [
                'name' => 'required',
                'detail' => 'required'
            ]);
           
            if($validator->fails()){
                return $this->sendError('Validation Error.', $validator->errors());       
            }
           
            $product = Product::create($input);
           
            return $this->sendResponse(new ProductResource($product), 'Product created successfully.');
        } 
         
        /**
         * Display the specified resource.
         *
         * @param  int  $id
         * @return \Illuminate\Http\Response
         */
        public function show($id): JsonResponse
        {
            $product = Product::find($id);
          
            if (is_null($product)) {
                return $this->sendError('Product not found.');
            }
           
            return $this->sendResponse(new ProductResource($product), 'Product retrieved successfully.');
        }
          
        /**
         * Update the specified resource in storage.
         *
         * @param  \Illuminate\Http\Request  $request
         * @param  int  $id
         * @return \Illuminate\Http\Response
         */
        public function update(Request $request, Product $product): JsonResponse
        {
            $input = $request->all();
           
            $validator = Validator::make($input, [
                'name' => 'required',
                'detail' => 'required'
            ]);
           
            if($validator->fails()){
                return $this->sendError('Validation Error.', $validator->errors());       
            }
           
            $product->name = $input['name'];
            $product->detail = $input['detail'];
            $product->save();
           
            return $this->sendResponse(new ProductResource($product), 'Product updated successfully.');
        }
         
        /**
         * Remove the specified resource from storage.
         *
         * @param  int  $id
         * @return \Illuminate\Http\Response
         */
        public function destroy(Product $product): JsonResponse
        {
            $product->delete();
           
            return $this->sendResponse([], 'Product deleted successfully.');
        }
    }

Step 7: Create Eloquent API Resources

php artisan make:resource ProductResource

app/Http/Resources/ProductResource.php

<?php
  
    namespace App\Http\Resources;
      
    use Illuminate\Http\Request;
    use Illuminate\Http\Resources\Json\JsonResource;
      
    class ProductResource extends JsonResource
    {
        /**
         * Transform the resource into an array.
         *
         * @return array
    
         */
        public function toArray(Request $request): array
        {
            return [
                'id' => $this->id,
                'name' => $this->name,
                'detail' => $this->detail,
                'created_at' => $this->created_at->format('d/m/Y'),
                'updated_at' => $this->updated_at->format('d/m/Y'),
            ];
        }
    }

Run Laravel App:

php artisan serve

make sure in details api we will use following headers as listed bellow:

'headers' => [

    'Accept' => 'application/json',
    
    'Authorization' => 'Bearer '.$accessToken,
    
    ]

Now, Follow The Steps:

1) Register API: Verb:GET, URL:http://localhost:8000/api/register

2) Login API: Verb:GET, URL:http://localhost:8000/api/login

3) Product List API: Verb:GET, URL:http://localhost:8000/api/products

4) Product Create API: Verb:POST, URL:http://localhost:8000/api/products

5) Product Show API: Verb:GET, URL:http://localhost:8000/api/products/{id}

6) Product Update API: Verb:PUT, URL:http://localhost:8000/api/products/{id}

7) Product Delete API: Verb:DELETE, URL:http://localhost:8000/api/products/{id}

Thank You.
