The AdWords API is no longer available for new users. Sign up for the Google Ads API instead.
Developers accepting the Terms and Conditions when applying for a new developer
token after April 28, 2021 are only given access to the Google Ads API. Using the
token for AdWords API calls results in a
error, with the message that new developers must use the Google Ads API.
Developer tokens (including regenerated ones) issued prior to April 28 can still be used for the AdWords API until sunset on April 27, 2022.
