    AWS3 and AWS4 Difference?

    Hi all,

    I am wondering, what is the difference between AWS3 and 4, other than the information that each presents?

    I've looked at the XML feed for both and can see that 4 offers much more information, but are they processed differently, or can you use any xml parser script you currently use with AWS3, on AWS4 (with the relevant adjustments to variable names, etc, to match the new info)?

    Some of the categories of information have sub categories in 4. The WSP AWS script needs some ammendment to dig into these categories and properly pull out the correct information (so in some cases if a field name is used more than once in 4 where 3 was expecting 1 value, you will get the last value returned, overwriting the earlier values)

    Im using AWS4 now, and essentially just modified my AWS3 script which was derived from the AWS article on this site.

    And yes you need to check carefully what you are getting back, as I had the problem Blue Cat mentioned. Also I think Amazon's offer appears as an offer like any other merchant.

    Yes, I saw that it returned mulitple values for 'features' (as an example).

    How did you fix that problem, r2?

    Thanks for the replies, guys

    You also need a new code as the old Dev Tokens no longer work in AWS 4. I forget what it's called but I asked for mine and got it within minutes.

    Also, AWS4 is quite a bit faster over all than AWS3 was.
