TribeHR, a software-as-a-service human resources solution, is bringing powerful API integration into the HR industry on multiple fronts. TribeHR co-founder Joseph Fung explained to us at SWSXi how APIs fit into the company's overall strategy:
It's no secret that Facebook's Graph API and widgets have contributed a great to Facebook's success and never-ending permeation of the web as we know it. Looking to make a similar move, LinkedIn has recently expanded its own developer platform and LinkedIn API. The new LinkedIn tools aren't just aimed at developers. With just a couple lines of code, you can begin integrating LinkedIn in to your web page with a variety of plugins and widgets.
