Have you ever wondered how Facebook is able to automatically display your Instagram photos? How about how Evernote syncs notes between your computer and smartphone? If so, then it’s time to get excited!

In this course, we walk you through what it takes for companies to link their systems together. We start off easy, defining some of the tech lingo you may have heard before, but didn’t fully understand. From there, each lesson introduces something new, slowly building up to the point where you are confident about what an API is and, for the brave, could actually take a stab at using one.

If you are a non-technical person, you should feel right at home with the lesson structure. For software developers, the first lesson or two may feel like a mandatory new employee orientation, but stick with it – you’ll get your fill of useful information, too.
