API’s

Application Programming Interface’s allow software, computers and Servers on the web to interact and talk to one another. An API works in a similar way to any other web space (What happens when you visit a web page). An API connects your computer (or device) to dynamic web servers and returns a response. However, unlike a web page it will only return data in the form of Json or XML.

An API will return an object back, (see Object Oriented Programming) whereas RESTful Web Services will return you the state of the object saving a large amount of overhead.


  • RESTful Web Services
    • API’s will send you data back from web Servers in the form of an object. This allows us to do many things but downloading all of this data comes with high overheads. This is where RESTful web services come in.
