If you want to connect it to the Kroger API, you'll need to sign up for a Kroger dev account here - https://developer.kroger.com/

Then go to "Manage" -> "Apps" and create a new app. Once you've done that, create a json file in your project with the following structure - obviously with your values filled in.

  {
      "ClientId": "",
      "ClientSecret": "",
      "RedirectUri": "",
      "KrogerUrl": "https://api.kroger.com/v1/"
  }

Then in KrogerAPIService, you'll just need to point it in the "GetStartupConfig" method to your file.

If you don't want to go through all those steps, then you'll need to do some code updates to remove the API calls throughout the app. Unless I decide to go in and make those conditional (which I probably will at some point, in case a user doesn't have internet connection).

After that, i think you'll just need to do the usual dotnet restore, etc, and you should be good to go? if not let me know in the YT comments, in case I'm forgetting something else. But ultimately, this is just an example app to give you ideas on things you can do in your own apps, and to see how I implemented them.
