I found various tutorials on how to create a web server/web API (I think these are one in the same). The tutorials I found use C# to demonstrate the tutorial. I believe the tutorials assumed knowledge the student has an understanding of protocols in order to understand the tutorial such as XML, JSON, etc..
I've written code for 46 years, however, I have not kept up on protocols for web services/web APIs. I'm looking for a beginners tutorial on how to create a web service/web API for a web application. This code will specifically allow me to interact with UPS (United Parcel Service).
Any assistance is most welcome using VB.NET.
