We’ve launched a new 
Shippingsettings service which supports the 
new shipping settings in Merchant Center. This service replaces the old 
Accountshipping service, which has been deprecated and will be retired 
March 1st, 2017.
The new service uses 
rate tables instead of rate trees to describe complex rate systems, and also supports 
retrieving the available shipping services. Check out the updated  
Account-level Tax and Shipping guide and 
reference documentation if you're interested in what the new service looks like!
A note to users of 
Accountshipping: you can retrieve settings uploaded via 
Accountshipping through 
Shippingsettings, but 
not vice versa. Thus, if you currently have shipping settings, you can see what your current settings would look like in the new format expected by 
Shippingsettings by retrieving them using the new service.
If you're migrating from 
Accountshipping, we suggest you either first experiment with 
Shippingsettings on another Merchant Center account used for testing, or keep the code to upload settings via 
Accountshipping around until you're sure your new 
Shippingsettings code behaves as expected.
If you have any questions or feedback on the 
Shippingsettings service or other questions about the Content API for Shopping, please let us know on the 
forum.
