Hello,

I'm make my first steps with the adwords api and PHP. I've an client-id, client-secret and refreshtoken, but after / during authentification a get the above error.

What exactly does it mean ? How I can fix it ?


Thanks in advance...

Hi Andy,

Try regenerating the refresh token once more. Looks like the refreshtoken grant changed after it was issued.

Hi Andy,

Could you double-check your steps against the ones listed on https://github.com/googleads/googleads-php-lib/wiki/Using-OAuth-2.0? If that doesn't work, pls open an issue on https://github.com/googleads/googleads-php-lib/issues and I'll ask the PHP library maintainer to follow up with you.

Hello,

I tried it again as suggested above, but it resulted in the same error. I open'd an issue:
