**Step 1: Install Laravel 9**

This is optional; however, if you have not created the laravel app, then you may go ahead and execute the below command:

```
composer create-project laravel/laravel example-app
```

**Step 2: Install Passport**

In this step we need to install passport via the Composer package manager, so one your terminal and fire bellow command:

```
composer require laravel/passport
```

After successfully install package, we require to get default migration for create new passport tables in our database. so let's run bellow command.

```
php artisan migrate
```

Next, we need to install a passport using a command, Using passport:install command, will create token keys for security. So let's run bellow command:

```
php artisan passport:install
```

**Step 3: Passport Configuration**

In this step, we have to configuration on three place model, service provider, and auth config file. So you have to just follow changes on that file.

In model we added HasApiTokens class of Passport,

In auth.php, we added api auth configuration.

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

```
<?phpreturn [    .....    'guards' => [        'web' => [            'driver' => 'session',            'provider' => 'users',        ],        'api' => [            'driver' => 'passport',            'provider' => 'users',        ],    ],    .....]
```

**Step 4: Add Product Table and Model**

next, we require to create migration for posts table using Laravel 9 php artisan command, so first fire bellow command:

```
php artisan make:migration create_products_table
```

After this command you will find one file in following path **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()    {        Schema::create('products', function (Blueprint $table) {            $table->id();            $table->string('name');            $table->text('detail');            $table->timestamps();        });    }      /**     * Reverse the migrations.     *     * @return void     */    public function down()    {        Schema::dropIfExists('products');    }};
```

After create migration we need to run above migration by following command:

```
php artisan migrate
```

After create "products" table you should create Product model for products, so first create file in this path app/Models/Product.php and put bellow content in item.php file:

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**

In this step, we will create api routes. Laravel provide api.php file for write web services route. So, let's add new route on that file.

**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**

in next step, now we have create new controller as BaseController, ProductController and RegisterController, i created new folder "API" in Controllers folder because we will make alone APIs controller, So let's create both controller:

app/Http/Controllers/API/BaseController.php

```
<?phpnamespace 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;   class RegisterController extends BaseController{    /**     * Register api     *     * @return \Illuminate\Http\Response     */    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 $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)    {        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;     class ProductController extends BaseController{    /**     * Display a listing of the resource.     *     * @return \Illuminate\Http\Response     */    public function index()    {        $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)    {        $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)    {        $product = Product::find($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)    {        $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)    {        $product->delete();             return $this->sendResponse([], 'Product deleted successfully.');    }}
```

**Step 7: Create Eloquent API Resources**

This is a very important step of creating rest api in laravel 9. you can use eloquent api resources with api. it will helps you to make same response layout of your model object. we used in ProductController file. now we have to create it using following command:

```
php artisan make:resource ProductResource
```

Now there created new file with new folder on following path:

app/Http/Resources/ProductResource.php

```
<?php  namespace App\Http\Resources;  use Illuminate\Http\Resources\Json\JsonResource;  class ProductResource extends JsonResource{    /**     * Transform the resource into an array.     *     * @param  \Illuminate\Http\Request  $request     * @return array|\Illuminate\Contracts\Support\Arrayable|\JsonSerializable     */    public function toArray($request)    {        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:**

All the required steps have been done, now you have to type the given below command and hit enter to run the Laravel app:

```
php artisan serve
```

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