Hi Lleandre,
Thank you for reaching out to the Google Ads API team.
With regard to,
"Is it possible to get all customer metrics in one query?", you can use the
customer report that will allow you to retrieve / fetch customer metrics. You can use this
Google Ads Query Builder for this report that will help you build and validate your query.
Also,
"Our method is extremely slow and takes 0.5 seconds each account it loads. We currently have just basic access.Would this be faster once we have standard access?", kindly note that the
access level determines whether you can affect production accounts and the number of operations and requests that you can execute daily. Meaning, whether you have basic or standard access, it wouldn't affect the time / speed of your reporting.
Regards,
