An Overview of APIs
As we increasingly rely on technology for automation and integration of our business and personal interests, API’s have become an integral part of our lives. Without knowing it, we are growing reliant on this sophisticated technology.

Most of the applications you use every day rely on APIs in some capacity.
These APIs act like building blocks, allowing developers to build applications much faster. They also prevent developers from having to “reinvent the wheel,” and spend time creating functionality that already exists.
