What is asynchronous in Web API?

What is asynchronous in Web API?

Synchronous/asynchronous APIs are application programming interfaces that return data for requests either immediately or at a later time, respectively. Synchronous/asynchronous APIs provide a way to make immediate or scheduled requests for resources, data or services when available.

Why use async in Web API?

If you have requests that access an external resource such as a database or a web API then async frees up the thread while it is waiting. This means you will use fewer threads, and so avoid reaching the maximum number of threads so quickly and use less memory as well.

What is async and await in C# Web API?
