For using the Ads API, we have an approved account but now we need separate accounts for staging and local dev so we can start developing and testing without changing the production account settings. There seems to be no way to do this as the sandbox accounts appear to be limited to premium / search products. What are we missing? Do we need to apply for multiple accounts to make this happen and if so how can we apply and say “we are approved app 123 and we just need this account approved for the same thing but we’ll use it for stage”?

Thanks.
