Laravel Sanctum Rest Api Authentication

I want to make a rest API authentication to my current project. I didn't want to make another project just for this API. Here I use Breeze first to be able to make login, register, and so on then I want to make Authentication for my mobile app.

If you're not using Breeze to install below if already install breeze then it's already installed sanctum in it, so go straight to making the controller.

composer require laravel/sanctum
php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider"
php artisan migrate

I've tested out using php artisan install:breeze api but I think it's not for what I'm trying to do.

Create BaseController in Api to make sendResponse & sendError function.

<?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);
    }
}

Create RegisterController extends BaseController to make register & login function.

<?php


namespace App\Http\Controllers\Api;


use Illuminate\Http\Request;
use App\Http\Controllers\Controller as Controller;
use Illuminate\Http\JsonResponse;
use Auth;
use Validator;
use App\Models\User;

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')->plainTextToken;
        $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')->plainTextToken;
            $success['name'] =  $user->name;

            return $this->sendResponse($success, 'User login successfully.');
        }
        else{
            return $this->sendError('Unauthorised.', ['error'=>'Unauthorised']);
        }
    }
}

Add to route api.php

Route::controller(RegisterController::class)->group(function(){
    Route::post('register', 'register');
    Route::post('login', 'login');
});

Then test it out on postman / insomnia.
