regionConfiguration

Returns information about the control, including the scope of the control, if enabled, and the Regions in which the control is available for deployment. For more information about scope, see Global services.

If you are applying controls through an Amazon Web Services Control Tower landing zone environment, remember that the values returned in the RegionConfiguration API operation are not related to the governed Regions in your landing zone. For example, if you are governing Regions A,B,and C while the control is available in Regions A, B, C, and D, you'd see a response with DeployableRegions of A, B, C, and D for a control with REGIONAL scope, even though you may not intend to deploy the control in Region D, because you do not govern it through your landing zone.
