Anyone has used this API before in your site, please let me how's the result as well as how to use it. Thanks
yahoo gives many APIs for its lot od products, which API you need to use. Also they are well documented and easy to use.
Since you have not mentioned exactly which Yahoo API, I have only come across one area of yahoo api which I needed use for that is yahoo site explorer api. I tried using it, but didnt complete the project, but the api looked pretty comprehensive and well-formed. It was completely in xml format - input, output, etc. Overall the impression was good.
Some examples of integration of Shopzilla / Shopping.com API can be found on Programmableweb: Shopzilla API mashups Shopping.com API mashups
I have ever tried to register in Shopping.com but they have denied my apps.And they dont tell me why.I dont like it
