At the request of several of your fellow publishers, we will be adding the ability to display offer markdown information within the Catalog API Product Service.
Currently, we offer actual price information tagged as <price> within the <Offer> element. Soon, we will additionally provide the original price and related markdown percentage to allow for display of markdown information for each offer. In the event an offer is not on sale, the response will return a markdown percentage of "0.00".
Release: Monday, September 27th
API Versions: Bizrate, Beso
The release of these new fields should not impact you unless you have developed a means of auto-generating your XML handling code based on the XML schema document for the Product Service. If you have done this, you will need to update your schema.
Don't forget to follow us on Twitter for snappy release notifications! Upon release, you will be able to see an example result set returned with this new value through our Catalog API Interactive Documentation. In order to access this documentation, you will need to log in with your Catalog API Key & Publisher ID. Once you are in there, view the Product Service Resource section. At the very bottom of this section, you will see a link "[ + ] show test form". This will allow you to test out queries, viewing sample XML.
As always, please do not hesitate to contact us should you have any questions.
