*The schedule is subject to change.

We will launch the conversion API for Search Ads.
The conversion API is designed to measure and optimize ad performance more accurately.
It is less affected by browser security restrictions and ad blockers, allowing advertisers to obtain more reliable tracking data.
Even if you can't use the current conversion tracking tag, this feature provides conversion tracking.

An environment that allows developing and managing applications using the API is required to use the conversion API.
Server-side Google Tag Manager is scheduled to support this feature around October 2025.
This API is available only for Search Ads. It is a different feature from the conversion API already offered for Display Ads.

For detailed specifications of the conversion API, see the following:
