We have set up a little demo .NET client written in C# for you to kick off development.
👉 Download the .NET demo client

The demo program requires two parameters, first one is the url to the API endpoint and the second one is the API key.
Open a command prompt window and cd to the demo folder.
Run the sample:

c:\...\demo> dotnet run -- https://api.pickup.bd.com your-api-key

If everything is ok with the url and API key you should see the message

"Connected. Press enter to disconnect..."

If you call the Web API with the same api key, you should see a notification in the terminal window.
