This is just a reference documentation and the remote requests will NOT work straight out of the documentation as they will send the request to "localhost" and this will lead to a "Cross-Origin Request Blocked" error.
For example: "http://localhost/rs/alerts/device". You can use these requests ONLY with your REST client.

You can also access the rest documentation straight from your running RM, just add "/restdoc" to your RM location.
For example "http://172.22.204Configuration Manager RESTful Web Service.114/restdoc", if you have your RM running on localhost use "http://localhost/restdoc".
