Introduction to Application Programming Interface (API)
Explore the basics of Application Programming Interfaces, their role as intermediaries in software communication, and key API architectures such as REST, SOAP, and RPC. Understand the distinctions among open, partner, internal, and composite APIs to build a solid foundation for API development.
We'll cover the following...
Application Programming Interface (API)
An Application programming interface (API) is simply an intermediary. Assume someone goes to a store to buy a bag. The bag is available in red, blue, and pink, but not black, which they prefer. So they approach the store clerk and inquire whether or not they have a black version in stock. The assistant then approaches the inventory manager to find its current availability.

Let’s take the analogy above and apply it to APIs:
-
The inventory manager is the data source. They hold the information needed, and the shopper must request to access this information. Rejection and granting of ...
