Whit Nelson, one of Mightybytes’ developers, has been stirring the cauldron of API development recently to make magic happen.

He’s been working with APIs—Application Programming Interfaces—which open up the inner workings of a product (such as Gmail, Twitter, etc) so that developers can create new applications and services around them. Working on a simple project with an API can mean great improvements for the whole ecosystem of users and developers.

When Emma gave Mightybytes a sneak peek at their API, Whit set out to integrate it with Highrise from 37 Signals. The result would be efficient: When companies sign up users for their newsletters, their lists of contacts in Highrise would be automatically synced with it.
