I tried to understand how Yahoo Contact works I have read the tutorial. And my question is, why Yahoo API is so hard to understand? why there are so many internal security process to go through by the developer rather than taking care of by Yahoo API?
I know how the Oauth works, but why any developer should even bother to know how it works? why it is not implemented in the Yahoo API it self rather than so many developers developing the same thing and seeing the same challenges?
