Starting 
today, we are deprecating the use of the 
Products.get and 
Products.list methods for retrieving 
all product attributes. These methods still work as expected today, but they may change in the future to return only partial information about products. If you want to retrieve all product attributes, you should use the 
Productstatuses.get and 
Productstatuses.list methods instead, which now optionally provide product attributes in addition to product issues and approval statuses.
Note that the Productstatuses.get and Productstatuses.list methods still do not return product attributes by default. To request product attributes be included, we have added an optional 
includeAttributes argument to these methods. When set, 
the resources returned by 
Productstatuses.get and 
Productstatuses.list will contain an additional 
product field that contains the 
attribute information.
If you have any questions or feedback about the changes to retrieving products or other questions about the Content API for Shopping, please let us know on the 
forum.
