how to use api in laravel 8 code example

Example 1: laravel api response trait

trait RespondsWithHttpStatus
{
    protected function success($message, $data = [], $status = 200)
    {
        return response([
            'success' => true,
            'data' => $data,
            'message' => $message,
        ], $status);
    }

    protected function failure($message, $status = 422)
    {
        return response([
            'success' => false,
            'message' => $message,
        ], $status);
    }
}

Example 2: laravel rest api

class RegisterTest extends TestCase
{
    public function testsRegistersSuccessfully()
    {
        $payload = [
            'name' => 'John',
            'email' => '[email protected]',
            'password' => 'toptal123',
            'password_confirmation' => 'toptal123',
        ];

        $this->json('post', '/api/register', $payload)
            ->assertStatus(201)
            ->assertJsonStructure([
                'data' => [
                    'id',
                    'name',
                    'email',
                    'created_at',
                    'updated_at',
                    'api_token',
                ],
            ]);;
    }

    public function testsRequiresPasswordEmailAndName()
    {
        $this->json('post', '/api/register')
            ->assertStatus(422)
            ->assertJson([
                'name' => ['The name field is required.'],
                'email' => ['The email field is required.'],
                'password' => ['The password field is required.'],
            ]);
    }

    public function testsRequirePasswordConfirmation()
    {
        $payload = [
            'name' => 'John',
            'email' => '[email protected]',
            'password' => 'toptal123',
        ];

        $this->json('post', '/api/register', $payload)
            ->assertStatus(422)
            ->assertJson([
                'password' => ['The password confirmation does not match.'],
            ]);
    }
}
