API Platform for Laravel Projects

API Platform is the easiest way to create state-of-the-art web APIs using Laravel!

With API Platform, you can:

• expose your Eloquent models in minutes as:
  • a REST API implementing the industry-leading standards, formats and best practices: JSON-LD/RDF, JSON:API, HAL, and many RFCs…
  • a GraphQL API
  • or both at the same time, with the same code!
• automatically expose an OpenAPI specification (formerly Swagger), dynamically generated from your Eloquent models and always up to date
• automatically expose nice UIs and playgrounds to develop using your API (Swagger UI and GraphiQL)
• automatically paginate your collections
• add validation logic using Laravel Form Request Validation
• add authorization logic using gates and policies (compatible with Sanctum, Passport, Socialite…)
• add filtering logic

• benefits from the API Platform JavaScript tools: admin and create client (supports Next/React, Nuxt/Vue.js, Quasar, Vuetify and more!)

• boost your app with Octane and FrankenPHP (the default Octane engine, also created by Kévin)
• decouple your API from your models and implement patterns such as CQRS
• test your API using convenient ad-hoc assertions that work with Pest and PHPUnit

Let’s discover how to use API Platform with Laravel!

API Platform can be installed easily on new and existing Laravel projects. If you already have an existing project, skip directly to the next section.

If you don’t have an existing Laravel project, create one. All Laravel installation methods are supported. For instance, you can use Composer:

composer create-project laravel/laravel my-api-platform-laravel-app
cd my-api-platform-laravel-app

In your Laravel project, install the API Platform integration for Laravel:

composer require api-platform/laravel

After installing API Platform, publish its assets and config:

php artisan api-platform:install

If it’s not already done, start the built-in web server:

php artisan serve

Open http://127.0.0.1:8000/api/, your API is already active and documented… but empty!

After installing API Platform, you can publish its assets and config using the api-platform:install Artisan command.

php artisan api-platform:install

To discover how API Platform framework works, we will create an API to manage a bookshop.

Let’s start by creating a Book model:

php artisan make:model Book

By default, Laravel uses SQLite. You can open the database/database.sqlite file with your preferred SQLite client (PhpStorm works like a charm), create a table named books, and add some columns, Eloquent and API Platform will detect these columns automatically.

But there is a better alternative: using a migration class.

First, create a migration class for the books table:

 php artisan make:migration create_books_table

Open the generated migration class (database/migrations/<timestamp>_create_books_table.php) and add some columns:

    public function up(): void
    {
        Schema::create('books', function (Blueprint $table) {
            $table->id();

+            $table->string('isbn')->nullable();
+            $table->string('title');
+            $table->text('description');
+            $table->string('author');
+            $table->date('publication_date')->nullable();

            $table->timestamps();
        });
    }

Finally, execute the migration:

php artisan migrate

The table and columns have been created for you!

Open app/Models/Book.php that we generated in the previous step and mark the class it contains with the #[ApiResource] attribute:

namespace App\Models;

+use ApiPlatform\Metadata\ApiResource;
 use Illuminate\Database\Eloquent\Model;

+#[ApiResource]
 class Book extends Model
 {
 }

Open http://127.0.0.1:8000/api/, tadam, your API is ready and entirely functional 🎉:

You can play with your API with the sandbox provided by SwaggerUI.

Under the hood, API Platform:

1. Registered the standard REST routes in Laravel’s router and a controller that implements a state-of-the-art, fully-featured, and secure API endpoint using the services provided by the API Platform Core library
2. Used its built-in Eloquent state provider to introspect the database and gather metadata about all columns to expose through the API
3. Generated machine-readable documentations of the API in the OpenAPI (formerly known as Swagger) (available at http://127.0.0.1:8000/api/docs.json) and JSON-LD/Hydra formats using this metadata
4. Generated nice human-readable documentation and a sandbox for the API with SwaggerUI (Redoc is also available out-of-the-box)

Imagine doing it all again, properly, by hand? How much time have you saved? Weeks, months? And you’ve seen nothing yet!

If you access any API URL with the .html extension appended, API Platform displays the corresponding API request in the UI. Try it yourself by browsing to http://127.0.0.1:8000/api/books.html. If no extension is present, API Platform will use the Accept header to select the format to use.

So, if you want to access the raw data, you have two alternatives:

• Add the correct Accept header (or don’t set any Accept header at all if you don’t care about security) - preferred when writing API clients
• Add the format you want as the extension of the resource - for debug purposes only

For instance, go to http://127.0.0.1:8000/api/books.jsonld to retrieve the list of Book resources in JSON-LD.

Of course, you can also use your favorite HTTP client to query the API. We are fond of Hoppscotch, a free and open source API client with good support of API Platform.

By default, a JSON-LD response is sent but many other formats, including CSV and JSON:API are supported. You can enable or disable formats in config/api-platform.php:

// config/api-platform.php

// ...
return [
    'formats' => [
        'jsonld' => ['application/ld+json'],
        'jsonapi' => ['application/vnd.api+json'],
        'csv' => ['text/csv'],
    ],

    'patch_formats' => [
        'json' => ['application/merge-patch+json'],
    ],

    'docs_formats' => [
        'jsonld' => ['application/ld+json'],
        'jsonapi' => ['application/vnd.api+json'],
        'jsonopenapi' => ['application/vnd.openapi+json'],
        'html' => ['text/html'],
    ],

    // ...
];

By default, only the REST endpoints are enabled, but API Platform also supports GraphQL!

Install the GraphQL support package:

composer require api-platform/graphql:^4

Then, enable GraphQL in config/api-platform.php:

     'graphql' => [
-        'enabled' => false,
+        'enabled' => true,

Then open http://127.0.0.1:8000/api/graphql and replace the default GraphQL query example with:

{
  books(first: 3) {
    edges {
      node {
        title
        author
        publicationDate
      }
    }
  }
}

You now have a REST and a GraphQL API with the same code!

As you can see, a nice UI (GraphiQL) is also available. The documentation is automatically generated using the GraphQL introspection endpoint.

API Platform allows to control which fields will be publicly exposed by the API using the same syntax as Eloquent serialization:

namespace App\Models;

use ApiPlatform\Metadata\ApiResource;
use Illuminate\Database\Eloquent\Model;

#[ApiResource]
class Book extends Model
{
    /**
     * The attributes that should be hidden (deny list).
     *
     * @var array
     */
    protected $hidden = ['isbn'];
}

namespace App\Models;

use ApiPlatform\Metadata\ApiResource;
use Illuminate\Database\Eloquent\Model;

#[ApiResource]
class Book extends Model
{
    /**
     * The attributes that should be visible (allow list).
     *
     * @var array
     */
    protected $visible = ['title', 'description'];
}

Let’s replace our author column with a relation to a new author table:

    public function up(): void
    {
        Schema::create('books', function (Blueprint $table) {
            $table->id();

            $table->string('description');
-            $table->string('author');
+            $table->integer('author_id')->unsigned();
+            $table->foreign('author_id')->references('id')->on('authors');

            $table->timestamps();
        });

+       Schema::create('authors', function (Blueprint $table): void {
+           $table->id();
+           $table->string('name');
+           $table->timestamps();
+       });
    }

By doing so, API Platform will automatically handle links to that relation using your preferred format (JSON:API, JSON-LD, etc) and when we request a Book we obtain:

{
    "@context": "/api/contexts/Book",
    "@id": "/api/books/1",
    "@type": "Book",
    "name": "Miss Nikki Senger V",
    "isbn": "9784291624633",
    "publicationDate": "1971-09-04",
    "author": "/api/authors/1"
}

To create a Book related to an author, you should use IRIs to reference the relation:

PATCH /api/books/1
Content-Type: application/merge-patch+json

{
    "author": "/api/authors/2"
}

There’s a powerful mechanism inside API Platform to create routes using relation (e.g.: /api/authors/2/books), read more about subresources here.

A must-have feature for APIs is pagination. Without pagination, collection responses quickly become huge and slow, and can even lead to crashes (Out of Memory, timeouts…).

Fortunately, the Eloquent state provider provided by API Platform automatically paginates data!

To test this feature, let’s inject some fake data into the database.

Instead of manually creating the data you need to test your API, it can be convenient to automatically insert fake data in the database.

Laravel provides a convenient way to do that: Eloquent Factories.

First, create a factory class for our Book model:

php artisan make:factory BookFactory

Then, edit database/factories/BookFactory.php to specify which generator to use for each property of the model:

 namespace Database\Factories;
 
 use Illuminate\Database\Eloquent\Factories\Factory;
 
 /**
  * @extends \Illuminate\Database\Eloquent\Factories\Factory<\App\Models\Book>
  */
 class BookFactory extends Factory
 {
     /**
      * Define the model's default state.
      *
      * @return array<string, mixed>
      */
     public function definition(): array
     {
         return [
-            //
+            'title' => mb_convert_case(fake()->words(4, true), MB_CASE_TITLE),
+            'isbn' => fake()->isbn13(),
+            'description' => fake()->text(),
+            'author' => fake()->name(),
+            'publication_date' => fake()->date(),
         ];
     }
 }

Then, update the app/Models/Book.php to hint Eloquent that it has an associated factory:

 namespace App\Models;
 
 use ApiPlatform\Metadata\ApiResource;
+use Illuminate\Database\Eloquent\Factories\HasFactory;
 use Illuminate\Database\Eloquent\Model;
 
 #[ApiResource]
 class Book extends Model
 {
+    use HasFactory;
 }

Reference this factory in the seeder (database/seeder/DatabaseSeeder.php):

 namespace Database\Seeders;
 
+use App\Models\Book;
 use App\Models\User;
 // use Illuminate\Database\Console\Seeds\WithoutModelEvents;
 use Illuminate\Database\Seeder;
 
 class DatabaseSeeder extends Seeder
 {
     /**
      * Seed the application's database.
      */
     public function run(): void
     {
         // User::factory(10)->create();
 
         User::factory()->create([
             'name' => 'Test User',
             'email' => '[email protected]',
         ]);
 
+        Book::factory(100)->create();
     }
 }

Finally, seed the database:

php artisan db:seed

ℹ️ Note

The fake() helper provided by Laravel lets you generate different types of random data for testing and seeding purposes. It uses the Faker library, which has been created by François Zaninotto. François is also a member of the API Platform Core Team. He maintains API Platform Admin, a tool built on top of his popular React-Admin library that makes creating admin interfaces consuming your API data super easy. What a small world!

Send a GET request on http://127.0.0.1:8000/api/books.

By default, API Platform paginates collections by slices of 30 items.

This is configurable, to change to 10 items per page, change app/Models/Book.php like this:

 namespace App\Models;
 
 use ApiPlatform\Metadata\ApiResource;
 use Illuminate\Database\Eloquent\Factories\HasFactory;
 use Illuminate\Database\Eloquent\Model;
 
-#[ApiResource]
+#[ApiResource(
+    paginationItemsPerPage: 10,
+)]
 class Book extends Model
 {
     use HasFactory;
 }

Read the pagination documentation to learn all you can do!

API Platform has a ton of knobs and gives you full control over what is exposed.

For instance, here is how to make your API read-only by enabling only the GET operations:

 // app/Models/Book.php
 namespace App\Models;

+use ApiPlatform\Metadata\Get;
+use ApiPlatform\Metadata\GetCollection;
 use Illuminate\Database\Eloquent\Model;

-#[ApiResource]
 #[ApiResource(
     paginationItemsPerPage: 10,
+    operations: [
+        new GetCollection(),
+        new Get(),
+    ],
 )]
 class Book extends Model
 {
 }

We’ll use configuration options provided by API Platform all along this getting started guide, but there are tons of features!

A good way to discover them is to inspect the properties of the ApiResource and ApiProperty attributes and, of course, to read the core library documentation.

You can change the default configuration (for instance, which operations are enabled by default) in the config (config/api-platform.php).

For the rest of this tutorial, we’ll assume that at least all default operations are enabled (you can also enable PUT if you want to support upsert operations).

API Platform provides an easy shortcut to some useful filters, for starters you can enable a PartialSearchFilter the title property:

 // app/Models/Book.php
 namespace App\Models;

 use ApiPlatform\Metadata\ApiResource;
+use ApiPlatform\Laravel\Eloquent\Filter\PartialSearchFilter;
 use Illuminate\Database\Eloquent\Model;

 #[ApiResource]
+#[QueryParameter(key: 'title', filter: PartialSearchFilter::class)]
 class Book extends Model
 {
 }

It’s also possible to enable filters on every exposed property:

 // app/Models/Book.php
 namespace App\Models;

 use ApiPlatform\Metadata\ApiResource;
+use ApiPlatform\Laravel\Eloquent\Filter\PartialSearchFilter;
+use ApiPlatform\Laravel\Eloquent\Filter\OrderFilter;
 use Illuminate\Database\Eloquent\Model;

 #[ApiResource]
+#[QueryParameter(key: ':property', filter: PartialSearchFilter::class)]
+#[QueryParameter(key: 'sort[:property]', filter: OrderFilter::class)]
 class Book extends Model
 {
 }

The OrderFilter allows us to sort the collection.

The :property placeholder gives the ability to create a parameter for each exposed property. These filters will be automatically documented:

On top of that, some validation rules are automatically added based on the given JSON Schema. You can customize the set of rules inside the constraints option of a QueryParameter.

API Platform comes with several filters dedicated to Laravel, check them out!

API Platform hooks into the native Laravel authentication mechanism.

It also natively supports:

• Laravel Sanctum, an authentication system for SPAs (single page applications), mobile applications, and simple, token-based APIs
• Laravel Passport, a full OAuth 2 server
• Laravel Socialite, OAuth providers including Facebook, X, LinkedIn, Google, GitHub, GitLab, Bitbucket, and Slack

Follow the official instructions for the tool(s) you want to use.

In Swagger UI, you can authenticate your requests using the Authorize button in the top right corner. To use it, you need to add some configuration in the config/api-platform.php file.

Here is an example of how to configure API key authentication:

// config/api-platform.php
'swagger_ui' => [
    'enabled' => true,
    'apiKeys' => [
        'api' => [
            'type' => 'header',
            'name' => 'X-API-Key'
        ]
    ]
]

Or if you are using Laravel Passport (or any other OAuth server):

// config/api-platform.php
'swagger_ui' => [
    'enabled' => true,
    'oauth' => [
        'enabled' => true,
        'type' => 'oauth2',
        'flow' => 'authorizationCode',
        'tokenUrl' => '<oauth_token_endpoint>',
        'authorizationUrl' =>'<oauth_authorization_endpoint>',
        'refreshUrl' => '<oauth_refresh_endpoint>',
        'scopes' => ['scope' => 'Description of the scope'],
        'pkce' => true,
    ]
]

A combination of both is also possible. For more information, you can also check the Swagger UI documentation.

It’s sometimes convenient to enforce the use of middleware for all API routes.

In the following example, we enable the Laravel Sanctum middleware for all API routes:

// config/api-platform.php
return [
    // ..
    'defaults' => [
        'middleware' => 'auth:sanctum',
    ],
];

To authorize write operations (POST, PATCH, PUT) and validate user input, you may generate a Form Request class:

php artisan make:request BookFormRequest

Then, add validation rules to the generated class (app/Http/Requests/BookFormRequest.php in our example):

 namespace App\Http\Requests;

 use Illuminate\Foundation\Http\FormRequest;

 class BookFormRequest extends FormRequest
 {
     /**
      * Determine if the user is authorized to make this request.
      */
     public function authorize(): bool
     {
-        return false;
+        return user()->isAdmin();
     }
 
     /**
      * Get the validation rules that apply to the request.
      *
      * @return array<string, \Illuminate\Contracts\Validation\ValidationRule|array<mixed>|string>
      */
     public function rules(): array
     {
         return [
-             //
+            'title' => 'required|unique:books|max:255',
+            'description' => 'required',
+            'author' => 'required|max:100',
         ];
     }
 }

In this example, we only authorize admin users to do write operations, and we add some validation rules.

If the standard Laravel conventions are followed, the Form Request class is autodetected and used automatically. Otherwise, reference it explicitly in the rules parameter:

 // app/Models/Book.php
 namespace App\Models;

+use App\Http\Requests\BookFormRequest;
 use Illuminate\Database\Eloquent\Model;

-#[ApiResource]
+#[ApiResource(
+    rules: BookFormRequest::class,
+)]
 class Book extends Model
 {
 }

API Platform will transform any exception in the RFC 7807 (Problem Details for HTTP APIs) format. You can create your own Error resource following this guide.

Read the detailed documentation about Laravel data validation in API Platform.

To protect an operation and ensure that only authorized users can access it, start by creating a Laravel policy:

php artisan make:policy BookPolicy --model=Book

Laravel will automatically detect your new policy and use it when manipulating a Book.

Read the detailed documentation about using Laravel gates and policies with API Platform.

Wouldn’t it be nice to have an administration backend to manage the data exposed by your API? Checkout API Platform Admin!

This Material Design admin is a Single Page App built with React Admin. It is powerful and fully customizable.

It leverages the Hydra documentation exposed by the API component to build itself. It’s 100% dynamic - no code generation occurs.

API Platform also has an awesome client generator able to scaffold fully working Next.js, Nuxt.js, React/Redux, Vue.js, Quasar, and Vuetify Progressive Web Apps/Single Page Apps that you can easily tune and customize. The generator also supports React Native if you prefer to leverage all capabilities of mobile devices.

The generated code contains a list (including pagination), a delete button, a creation and an edit form. It also includes Tailwind CSS classes and ARIA roles to make the app usable by people with disabilities.

Checkout the dedicated documentation.

Now that you learned the basics, be sure to read the general design considerations and how to extend API Platform to understand how API Platform is designed, and how to hook your custom business logic!

While attributes (introduced in PHP 8) are the preferred way to configure your API Platform resources, it’s also possible to use a trait instead.

These two classes are strictly equivalent:

// Attributes
namespace App\Models;

use ApiPlatform\Metadata\ApiResource;
use Illuminate\Database\Eloquent\Model;

#[ApiResource]
class Book extends Model
{
}

// Trait
namespace App\Models;

use ApiPlatform\Metadata\IsApiResource;
use Illuminate\Database\Eloquent\Model;

class Book extends Model
{
    use IsApiResource;
}

When using the IsApiResourceTrait, it’s also possible to return advanced configuration by defining an apiResource() static method.

These two classes are strictly equivalent:

// Attributes
namespace App\Models;

use ApiPlatform\Metadata\ApiResource;
use Illuminate\Database\Eloquent\Model;

#[ApiResource(
    paginationItemsPerPage: 10,
    operations: [
       new GetCollection(),
       new Get(),
    ],
)]
class Book extends Model
{
}

// Trait
namespace App\Models;

use ApiPlatform\Metadata\IsApiResource;
use Illuminate\Database\Eloquent\Model;

class Book extends Model
{
    use IsApiResource;

    public static function apiResource(): ApiResource
    {
        return new ApiResource(
            paginationItemsPerPage: 10,
            operations: [
                new GetCollection(),
                new Get(),
            ],
        );
    }
}

It’s quite common to define multiple ApiResource, ApiProperty, and Filter attributes on the same class. To mimic this behavior, the apiResource() function can return an array instead of a single instance of metadata class.

These two classes are strictly equivalent:

// Attributes
namespace App\Models;

use ApiPlatform\Metadata\ApiResource;
use ApiPlatform\Metadata\QueryParameter;
use ApiPlatform\Laravel\Eloquent\Filter\PartialSearchFilter;
use App\Http\Requests\BookFormRequest;
use Illuminate\Database\Eloquent\Model;

#[ApiResource(
    paginationEnabled: true,
    paginationItemsPerPage: 5,
    rules: BookFormRequest::class,
    operations: [
        new Put(),
        new Patch(),
        new Get(),
        new Post(),
        new Delete(),
        new GetCollection(),
    ]
)]
#[QueryParameter(key: ':property', filter: PartialSearchFilter::class)]
class Book extends Model
{
}

// Trait
namespace App\Models;

use ApiPlatform\Metadata\IsApiResource;
use ApiPlatform\Metadata\QueryParameter;
use ApiPlatform\Laravel\Eloquent\Filter\PartialSearchFilter;
use App\Http\Requests\BookFormRequest;
use Illuminate\Database\Eloquent\Model;

class Book extends Model
{
    use IsApiResource;

    public static function apiResource(): array
    {
        return [
            new ApiResource(
                paginationEnabled: true,
                paginationItemsPerPage: 5,
                rules: BookFormRequest::class,
                operations: [
                    new Put(),
                    new Patch(),
                    new Get(),
                    new Post(),
                    new Delete(),
                    new GetCollection(),
                ]
            ),
            new QueryParameter(key: ':property', filter: PartialSearchFilter::class),
        ];
    }
}
