We're pleased to announce that v202205 of the Google Ad Manager API is available starting today, May 17th. This release adds support for CPM sponsorships for ProposalLineItems.

It also updates the ReportService for the upcoming "Ad Exchange Historical" to "Historical" report type conversion. Ad Exchange Historical dimensions and metrics are now available for Historical reports. Because of this change, several Ad Exchange dimensions and metrics have been renamed or replaced in the API.

To migrate, please refer to the migration guide and the reference documentation for v202202 and earlier. The reference documentation has been updated to show which values are deprecated and their replacements. Here’s an example:

Enumeration	Description
AD_EXCHANGE_IMPRESSIONS	Ad Impressions on mapped Ad Exchange properties. When multiple text ads fill a single display slot it is only counted once, when the top text ad is recognized. In these cases, the Ad Impression is attributed to the top text ad. Deprecated as part of the "Ad Exchange Historical" to "Historical" report type conversion. Use AD_EXCHANGE_LINE_ITEM_LEVEL_IMPRESSIONS instead.

For the full list of changes, check the release notes. Feel free to reach out to us on the Ad Manager API forum with any API-related questions.
