Microsoft Advertising has introduced significant updates to its API, with new capabilities for tool builders and agencies managing accounts at scale.
Conversion value rules can now be managed in bulk via the Bulk API, allowing adjustments to conversion values based on conditions like location, device, or audience.
Additionally, AI-powered text recommendations can now include a tone, offering options such as Friendly, Persuasive, Cute, and Inspiring.
A new BrandExclusionSetting allows for product-ads opt-out in campaigns via a boolean setting, enhancing campaign control.

This update also marks the start of API versioning, where new response fields are automatically returned per the specified Api-Revision date, streamlining the process by removing the need for AdditionalFields.
