Lidl Plus .NET API client
This library allows you to query your Lidl Plus receipts, coupons and stores. It even allows you to generate a PNG receipt to use in your automation scripts, e.g. automatically add a receipt to your transactions.
This library is available as a NuGet package.
Run Install-Package Net.Bluewalk.LidlPlus in the Package Manager Console or search for "LidlPlus" in your IDE's package management plug-in.
First of all you need to get your refresh_token from your app. To do this you need to set up a MITM proxy and capture traffic.
You can do this with Fiddler or Proxie. Install the CA certificate on your phone, start capture and start your Lidl Plus app.
You'll see a request going to https://accounts.lidl.com/connect/token which will use your refresh_token.
var client = new Client("myrefreshtoken");
var receipts = await client.GetTickets();
var latest = await client.GetTicketImage(receipts.Records.FirstOrDefault().Id);
File.WriteAllBytes("receipt.png", latest);
