Since there is no option on the Trend Cloud One - Workload Security console to unregister Trend Vision One XDR, we need to wait for a maximum of 24 hours for the enrollment status to sync in the back-end. If there is a need to change it immediately, we can delete the registration via API call. The following steps uses Postman app to execute the API requests.
- Generate an API key on the Trend Cloud One - Workload Security account. Refer to the Create an API key topic for reference.
- Download and install Postman.
- Turn off Postman SSL certificate verification. Go to File > Settings.
- Open the Postman app then click New.
- Click HTTP Request.
- Set the HTTP method to DELETE then add the XDR registration ID on the request URL.
DELETE https://workload..cloudone.trendmicro.com/api/xdrregistrations/1?force=true
