Customizing historical data pull range

Org Management API is available for the Scale plan.
You can configure the historical pull range using the Team Data Pull Preferences feature of the Org Management API. You can specify a number of days to backfill that uniformly applies to all resources of a provider, as well as overriding the the number of days to backfill for specific resources.
The Team Data Pull Preferences you specified is advisory. There are scenarios in which Vital systems may not adhere strictly to your stated preferences.
