AuthenticationError.NOT_ADS_USER Error when integrate adWard to salesforce

[jitendra rawat]

How I can resolve this issue. What is the possible solution or reasons for this.

I am fetching performance report from adword and i have developer token and also got the Auth token for scope "'https://adwords.google.com/api/adwords/"

Hello,

This error normally means you have generated the refresh token with a wrong account. Try logging off and re-authorizing your application logging in as your AdWords user.

Hi,

I am using google service account to authentication during authentication follow this document "https://developers.google.com/accounts/docs/OAuth2ServiceAccount".

If you want then i can provide the apex code. Noted that I am facing this error when try to fetch performance report into salesforce.

Hello,

As the document says, we strongly discourage to use Service Accounts with AdWords. It's much easier to obtain and use an offline refresh token.

If you are still using it and have a google apps domain, you need to grant a user rights to access the correct account and set impersonation address to this user email address.

If we don't have a Google Apps domain, is it still possible to grant an MCC that same user rights access?

Hello Jamie,

Yes, you need to retrieve a refresh token for a user that has access to the given AdWords account as described here:
