On November 17th, 2015 , we'll be updating the Ad Exchange Seller REST API to make it consistent with the user interface. Specifically, we'll remove the ability to download saved reports or retrieve the dimensions we retired in April .
Requests made after this date for these dimensions will result in that dimension being ignored and requests for saved reports will result in an error.
As a reminder, the dimensions we retired in April are:
AD_FORMAT_CODE
AD_UNIT_ID
AD_UNIT_CODE
DSP_ID
EXPANSION_TYPE_CODE
PLATFORM_TYPE_CODE
For a full list of available dimensions, please see the AdX Seller REST API documentation .
Follow our Google+ page for other announcements and updates.
