Amazon MWS API : stack order of _POST_PRODUCT_DATA

Question

I was wondering if I could stack _POST_PRODUCT_DATA_ feedtype to Amazon like pricing ?

I tried it and Amazon failed to recognize the second product (the first one is ok, used the same Marketplace and same seller)

I'm trying to add multiple products to Amazon. Right now it's working fine with less than 50 products per hour.

How could I get the exact limit for such feeds ? I know that the SubmitFeed operation has a maximum request quota of 15 and a restore rate of a request every 2 minutes.

But for instance, can't I send in one feed 10 products or more ?

Answer 1

There is no limit on the number of products you send in one feed, but the size of the feed is limited to 2,147,483,647 bytes. For best performance, Amazon recommends keeping the feed size under 10MB. http://docs.developer.amazonservices.com/en_US/feeds/Feeds_SubmitFeed.html

If one of your products failed to update then you can usually find out why by calling GetFeedSubmissionResult (part of the Feeds API).

Edit: Here is an example _POST_PRODUCT_DATA_ feed with multiple products. The messages are derived from examples in the Selling on Amazon Guide to XML.
