In October 2015, we announced the Google My Business API and the sunset of manual location extensions in AdWords. To give developers more time to migrate their locations from AdWords to Google My Business, we have decided to extend the manual location extensions sunset and voluntary migration deadline beyond March 31. Existing locations in AdWords will not be auto-migrated until further notice. We will announce the revised sunset timeline and more details about auto-migration on this blog at a future date. Apologies for any inconvenience, please contact us if you have any questions.
