What is an Http endpoint ?

 

In simple words, It's a URL in a web application/Api like ("https://www.mysite.com/home"  or "https://localhost:5001/Account/index" ).

Basically it's a combination of 

•                 Network protocol (like http/https, etc.).
•                 Server address and port (like localhost:5001, etc.)
•                 URI (to uniquely identify a resource like account/index, etc.)
