Announcing v201808 of the Google Ad Manager API

We're happy to announce that v201808 of the Google Ad Manager API is available starting today. This version brings several new forecasting features, including forecast breakdowns by date and targeting. You can also forecast for AMP-only traffic and Proposal Line Items.

For video users, note that the new requestPlatformTargeting field is required when creating video line items.

For a full list of API changes in v201808, see the release notes.

If you're using one of our client libraries, you'll notice they've been updated to reflect our new name, so allow extra time for upgrading. A migration guide for each client library is available on GitHub: For questions about this or any other API changes, reach out to us on the Ad Manager API forums.
