Hi Ankit,

Thank you for reaching out. The "invalid_grant" error usually indicates that the access or refresh token being passed in your request is incorrect or invalid. Please make sure the email address used to generate the OAuth credentials has access to your account. If it does, please try generating a new set of OAuth credentials by following the guide here.

If you are still having an issue, please share the email address you are using to generate the credentials as well as your client customer ID.

Thanks,

Hi Ankitt,

The AuthenticationError.CUSTOMER_NOT_FOUND error is encountered when no Google Ads account is found for the customer Id provided in the header. Could you please confirm if the client customer Id(CID) belongs to a valid account and if the OAuth2 credentials were created using an email address which has access to your account(s). If the issue still persists, could you please share the complete request and error response logs for me to investigate further?

Thanks for give me the solutions. I did investigate this. But I am getting same error.

Google have 3 types of adwords account.

1) MCC account

2) Manager account

3) Client account.

I am right?

When I try to allow the oauth2 service with Manager account then I got success.

When I try to allow the oauth2 service with Client account then I got success.

When I try to allow the oauth2 service with MCC account then I got error. "CUSTOMER_NOT_FOUND"

I means, I want to get MCC account ID and LINK WITH OUR MCC ACCOUNT.

Please let me know if you have more questions.
