In the following example, Cyrus invites Wilfredo, Bernard, and Mike to a single instance event by simply creating a new scheduling object resource in one of his calendar collections by using the PUT method.

HTTP/1.1 201 Created Content-Length: 0 Date: Tue, 02 Jun 2009 18:52:54 GMT Last-Modified: Tue, 02 Jun 2009 18:52:54 GMT ETag: "d85561cfe74a4e785eb4639451b434fb" Schedule-Tag: "488177c8-2ea7-4176-a6cb-fab8cfccdea2"
Once the event creation has been completed, Cyrus's client will retrieve the event back from the server to get the schedule status of each "Attendee", as well as record the Schedule-Tag value for future use. In this example, the server reports that a scheduling message was delivered to Wilfredo, a scheduling message is still pending for Bernard, and the server was unable to deliver a scheduling message to Mike.
