Hi Hari, Refresh tokens and the rest of the credentials should be created using an email address that has access to a specific client account. For simplicity, if you wish to be able to use only a single set of OAuth2 credentials, I would recommend that you identify an email address which has access to your Root MCC account and while logged in to the said email address, you may then generate the OAuth2 credentials <https://developers.google.com/adwords/api/docs/guides/authentication> (refreshToken, clientId and clientSecret).
This will allow you to automatically have access to all other sub accounts under the said MCC. I hope this has been helpful and feel free to write back for any follow ups.
