Logout not working

I am new to Laravel

I am busy creating an API and I have the registration working and the login working. I am using Postman to test.

I cannot get the logout to work and I keep getting an error in the postman console telling me: Route [login] not defined.

So I presume Laravel is routing you to the web based login route after logging out, but since this is an api there is no web based login route. Why is Laravel redirecting you to the login route if you are using Sanctum and the project is using api.php? Does Laravel not know it's an API? How do I get past this so the user token gets deleted and I just get a json response?

Here is my logout controller file:

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class LogoutController extends Controller
{
    public function logout(Request $request)
    {
        $user = Auth::guard('sanctum')->user();

        if ($user) {
            $user->currentAccessToken()->delete();
            return response()->json(['message' => 'Logout successful'], 200);
        }

        return response()->json(['message' => 'No user logged in'], 401);
    }
}

and here is my route: Route::middleware('auth:sanctum')->post('/logout', [LogoutController::class, 'logout']);
