How to cancel async Task from the client
I have on ASP.Net C# web API with an endpoint for the import. Javascript client sends a list of items to this API and API process this list in another thread (long task) and immediately returns unique id (GUID) of process. Now I need the cancel the background task from the CLIENT. Is possible to somehow send the cancelation token from the client? I have tried to add CancellationToken as a parameter to my controller async action but I don’t know how to pass it from the client. For simplification, we can use as the client the Postman app.
