patch https://cloud.tenable.com/was/v2/scans/
Update the requested_action attribute for a scan. The requested action must be valid for the scan's current status. For example, you can stop a scan if it has a status of running. Otherwise, Tenable Web App Scanning returns a 409 reponse code. This request creates an asynchronous update job.
Requires SCAN OPERATOR [24] user permissions and CAN EXECUTE [32] scan permissions. See Permissions.
