I'm doing the migration from Adwords API to Google Ads API.
On Adwords we were working with CAMPAIGN_PERFORMANCE_REPORT and ACCOUNT_PERFORMANCE_REPORT. Now we can get a performance report using campaign o customer resources.
We have many active customers on the account but not all of them have activity all the days.
So I need to get a Performance Report only for the customers or campaigns that have cost on a specific date.
How can I get a list of all customers that have activity given a specific date? An after that, consume campaign/customer resources only for that customer ids?
