Create Laravel API Authentication Using Passport

Step 1: Install Laravel 8 for REST API with Passport Authentication

In this step, we will create laravel 8 application using the below command.

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

Step 2: Install Passport

Now, We are required to install the passport via the composer package manager. So, in your terminal run the below command.

composer require laravel/passport

After installation of the package, We are required to get default migration to create new passport tables in our database. So, run the below command.

php artisan migrate

Now, We will install the passport using the passport:install command. which will create token keys for security.

php artisan passport:install

Step 3: Passport Configuration

Now, We have to configure the model, service provider, and auth config file.

1. HasApiTokens class of Passport has been added in the User model,

Add the below code in app/User.php

1. In AuthServiceProvider we have added "Passport::routes()"

Add the below code in the app/Providers/AuthServiceProvider.php

1. We have added API auth configuration in the auth.php file.

In config/auth.php add the below code.

Step 4: Add Table and Model

In this step, We will create migration of the Product table using the PHP artisan command. So, run the below command in your terminal.

php artisan make:migration create_products_table

After running the above command, you will find migration in this path database/migrations. So, add the below code in your migration file to create the products table.

Now, run the below code in the terminal to create a migration.

php artisan migrate

And add the below code in the app/Product.php file

Step 5: Create API Routes

In this step, we will create API routes. Laravel provides an api.php file for writing web services routes. So, let's add a route in the routes/api.php file.

Step 6: Create Controller

Now, I have created BaseController, ProductController, and RegisterController in API folder.

app/Http/Controllers/API/BaseController.php

app/Http/Controllers/API/ProductController.php

app/Http/Controllers/API/RegisterController.php

Now, I have used POSTMAN API for testing purposes, Postman is a collaboration platform for API development. Postman's features simplify each step of building an API and streamline collaboration so you can create better APIs—faster.

Here I have added some screenshots with descriptions of the postman for your better understanding. First of all, we need to register in postman to check our example.

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

2 - After successfully registering in postman we need to add an access token in headers.

3 - Login API: Verb:GET, URL:http://localhost:8000/api/login
