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:

  • DSP_ID

For a full list of available dimensions, please see the AdX Seller REST API documentation.

Follow our Google+ page for other announcements and updates.
