As of October 12, 2021, v1.4 of the AdSense Management API is no longer available. If you need to use the AdSense Management API going forward, you should migrate to v2.
We’re temporarily accepting extension requests for v1.4 of the AdSense Management API. If you would like to request an extension, please send us your project number. Note that this is a short extension period. All extensions will expire on October 26, 2021 regardless of when the request was made.
You can request an extension by completing the following steps:
Sign into your account in the Google Cloud Platform Console.
Make sure the correct project is selected.

Send an email to “adsenseapi-tech [at] google [dot] com” with the subject “Extension Request” and your project number from Step 4. It will take approximately 1 business day for the extension to take effect.
