Service Account to access MCC that are not linked

[Todd Evans]

We have a scenario in which we need ReadOnly access to our customers MCC account that is not linked to our MCC account..  We are currently using an email address to access this account as ReadOnly and that works just fine.

We would like to use a Service Account instead of our email address.

We cannot link that MCC account to our MCC account as this would give us some level of Admin rights.

Will using a Service Account in this scenario work for us?

Hi Todd,

Thank you for reaching out.

From the APIs' perspective in authenticating your API requests, we strongly recommend using OAuth2 desktop app or web app flow instead of service accounts unless you need a domain-specific feature (for example, impersonation), as mentioned (Key Point section) here.

Moving forward, as for whether you can assign read only access to the said service account and for further insight / guidance on the appropriate setup for your requirement, I would recommend that you reach out to the Google API Console instead, via this link. I hope this helps.

Best regards,
