Beginner APIs
APIs are purpose built application program interfaces. Good APIs usually serve as the universal portal to a system, anything you can do through the purpose built application can also be performed programmatically through the API. This allows systems to integrate.
Practice working with different APIs:
The Twitter API was difficult for me to obtain. I had to provide details on how I planned to use their service before being allowed to examine the service.
