How to send infolog messages / errors from C# in F&O?

Hello,

I’m calling an API from C#, and I need to display the authentication error, or any other error from the service.

I want to send the error to the client like this

Error(“Authentication error”);

But from C#. Just want something like an info message but from C# to the client in Dynamics.

How can I achieve this? Console.WriteLine wasn’t useful for me.
