The DoubleClick Ad Exchange (AdX) Buyer SOAP API and legacy AdX UI will be sunset in January, 2016. After the API is sunset, all static bidding campaigns will be terminated, and requests against any version of the API from AdX accounts will result in an error response. In addition, the legacy AdX UI will no longer be accessible.

As an alternative to the SOAP API, we recommend using the DoubleClick Ad Exchange Hosted Bidding solution. Similar to the static bidding functionality offered by the SOAP API and legacy UI, Hosted Bidding allows you to bid on Ad Exchange inventory without an external real-time bidding platform. At this time, Hosted Bidding is only accessible as a UI that can be found by signing in to your Ad Exchange Account and clicking the Hosted Bidding tab. To learn more, read the Hosted Bidding guide.

These sunsets will not affect real-time bidding applications. All features required to configure real-time bidding campaigns were migrated to the DoubleClick Ad Exchange Buyer REST API when we updated our pretargeting capabilities in July 2014.

If you have any comments or questions about the upcoming sunset, feel free to contact us via the forum or our Ads Developer G+ page.
