I have developed a music app for Android. At one stage in the application, the users can click on a song that they liked (when it was playing) and I'd like to be able to direct them to download it. This should preferably generate revenue as an affiliate purchase however I can't find a company which offers this service. I know Amazon has a product API but it seems they forbid using it in mobile applications. I saw this thread and it didn't give any useful information:
Advice on Affiliate Programs for Music for Android app
Has anyone used a web service to accomplish this?
Did you try http://www.barnesandnoble.com/affiliate/index.asp ? They seem pretty open by reading the FAQ. Note that I have no experience dealing with it.
There's also Best Buy affiliate progam.
And, finally, how can we forget about Walmart?
