Q: customer reviews - how do I get id of a review?

Hi,

I'm trying to use the following api to get the reviews of my app:

https://itunes.apple.com/us/rss/customerreviews/id=<APP_ID>/page=1/sortBy=mostRecent/xml.

Each review entry contains id and uri . for example:

<entry>

</entry>

Which one of them contains the id of the review?

I'm asking since the id field was changed for one of the reviews I retrieved yesterday.

Thanks,

Tali gillon
