I have seen that some developers are facing problems in developing with the Yahoo API and I have seen somewhere a simple tutorial to illustrate yahoo Apis. The example uses PHP with serialised output (which is the easiest to understand and implement) along with the Inbound Links API.

Here is the tutorial :

Hope it helps

    

Cool post, I didn't know the API could do things like that. I always assumed it was just for setting up ads for some reason.

Yes it is true. Many developers are having problems with the yahoo API.

Have somebody also an example that uses Java?

API allows applications to perform functions normally executed on the YouTube website. The API enables your application to search for YouTube videos and to retrieve standard video feeds, comments and video responses. In addition, the API lets your application upload videos to YouTube or update existing videos. Your application can also retrieve playlists, subscriptions, user profiles and more.

Thanks for the info...
