Today we’re announcing the v1.3 release of the Ad Exchange Buyer REST API. This release improves the behavior of creative submission by allowing you to resubmit creatives with the same buyer creative ID. If you resubmit a creative with the same ID, the new creative will replace the old and will initiate a new review. Additional information about the changes implemented in v1.3 can be found in our release notes and in the reference documentation.

You can contact us on our forum to discuss these changes, and to keep informed on all of our ads-related technologies, follow the Google Ads Developers Google+ page.
