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 pause or stop a scan if it has a status of running or resume a scan if it has a status of paused. Otherwise, Tenable Web App Scanning returns a 409 response code. This request creates an asynchronous update job.
Requires the Scan Operator [24] user role or the
WAS.SCAN_WAS.MANAGE custom role privilege. Additionally, requires the Can Execute [32] scan permission. See Roles and Permissions.
