This project contains a Web API for receiving payment notifications from Mobile Bux.
To run the API you will need to have .NET Core 3.1 installed. From the command line you can build the project using the following command:
$ dotnet build
You can then run the API locally using:
$ dotnet run
The application requires two secrets in order to be able to run correctly. Specifically, in appsettings.json you need to add the connection string and name for your EventHub. (In production you may also choose to inject these values in a different way than putting them directly into appsettings.json).
The API exposes one endpoint POST /payment_notifications. The JSON payload for this request contains a single parameter: 'Amount'. With the application running locally you can therefore test the API with something like the following:
$ curl -v -X POST -H 'Content-Type:application/json' -d '{\"Amount\": 100}' http://localhost:5000/payment_notifications
Alternatively, in PowerShell this would look something like:
$payment = @{
Amount=100
}
$json = $payment | ConvertTo-Json
Invoke-RestMethod 'http://localhost:5000/payment_notification' -Method Post -Body $json -ContentType 'application/json'
## Other Notes
Because this exercise is being shared with candidates with varying amounts of C#/.NET experience the code has been written in as simple a manner as possible, minimizing cleverness and indirection in favour of simple, procedural code. If you have any feedback on how to make this codebase clearer though please share!
