We're making a few changes to the AdSense APIs in line with our efforts to modernize AdSense.
AdSense Management API
We’ve launched version 2 of the AdSense Management API. For a detailed list of what's changing, review the developer release notes. Also note that the current version of the AdSense Management API (version 1.4) will stop returning responses on October 12, 2021. You can keep using version 1.4 up until this date, but we recommend that you start to use version 2 as soon as possible to ensure continuity.
AdSense Host API
We're changing some of the behaviors of the AdSense Host API. For a detailed list of what's changing, review our developer release notes. These changes will come into effect on October 12, 2021.
