What to do next after installed shopify-api-php and merged shopify-app-template-php

Hi.

I'm new on developing Shopify Custom App.

1. I have created the custom app as explained in this page .
2. I have installed Laravel on the server as explained in this page.
3. I have installed this library and merged this template.
4. I have created the test shop and could installed the custom app from the shop admin panel into the shop successfully.
5. Next I want to authenticate the shop and there is a route to authenticate the shop in the template as follows:
   

   Route::get('/api/auth', function (Request $request) {
       $shop = Utils::sanitizeShopDomain($request->query('shop'));
   
       // Delete any previously created OAuth sessions that were not completed (don't have an access token)
       Session::where('shop', $shop)->where('access_token', null)->delete();
   
       return AuthRedirection::redirect($request);
   });
   
   Route::get('/api/auth/callback', function (Request $request) {
       $session = OAuth::callback(
           $request->cookie(),
           $request->query(),
           ['App\Lib\CookieHandler', 'saveShopifyCookie'],
       );
   
       $host = $request->query('host');
       $shop = Utils::sanitizeShopDomain($request->query('shop'));
   
       $response = Registry::register('/api/webhooks', Topics::APP_UNINSTALLED, $shop, $session->getAccessToken());
       if ($response->isSuccess()) {
           Log::debug("Registered APP_UNINSTALLED webhook for shop $shop");
       } else {
           Log::error(
               "Failed to register APP_UNINSTALLED webhook for shop $shop with response body: " .
               print_r($response->getBody(), true)
           );
       }
   
       $redirectUrl = Utils::getEmbeddedAppUrl($host);
       if (Config::get('shopify.billing.required')) {
           list($hasPayment, $confirmationUrl) = EnsureBilling::check($session, Config::get('shopify.billing'));
   
           if (!$hasPayment) {
               $redirectUrl = $confirmationUrl;
           }
       }
   
       return redirect($redirectUrl);
   });

   But I have no idea how to call this route.

Can anyone let me know how to authenticate or show me the explanation or sample?

Thanks in advance.

I could solve this issue by myself.

I updated the application URL with /api/auth from the dashboard and installed the application then this url was called and authenticated.
