Mobile commerce is a huge business opportunity because, at least in the United States, there is not much infrastructure to support it. That's why mobile platform company Appcelerator recently announced its integration with the PayPal API. Now iPhone, Android and iPad developers using the paid version of the company's Titanium framework also get the ability to conduct mobile commerce.
Apple has had a busy 2015: It has not only evolved its existing SDKs, but added new SDKs to support newer platforms. This includes, notably, the Apple Watch update. Apple has also introduced innovative SDKs that have enabled the addition of functionality to everything from Search APIs to 3D Touch.
One of the bigger challenges with anything involving APIs is scale. As the number of APIs proliferate, the scalability demands from a management perspective become increasing untenable. Nowhere does that become more apparent than when dealing with mobile computing applications.
