By default, ArcGIS portals (including ArcGIS Online) allow cross-domain requests using CORS. If you configure the Organization | Settings | Security | Allow Origins setting in the portal that you use with VertiGIS Studio Reporting, then you must add VertiGIS Studio Reporting as an allowed origin.

The origin to allow depends on your deployment:

•ArcGIS Online with Cloud Reporting: If you use ArcGIS Online with cloud Reporting and your organization has configured the Allow Origins setting in ArcGIS Online, then you must add apps.vertigisstudio.com as an allowed origin.

•ArcGIS Online with On-Premises Reporting: If you use ArcGIS Online with on-premises Reporting and your organization has configured the Allow Origins setting in ArcGIS Online, then you must add your VertiGIS Studio Reporting server as an allowed origin.

•On-Premises Portal for ArcGIS with On-Premises Reporting: If you use an on-premises portal with on-premises Reporting and your organization has configured the Allow Origins setting in your portal, then you must add your VertiGIS Studio Reporting server as an allowed origin.
