* Note: The above code does not need to be repeatedly called for each REST request.
* The rest object can be setup once, and then many requests can be sent.  Chilkat will automatically
* reconnect within a FullRequest* method as needed.  It is only the very first connection that is explicitly
* made via the Connect method.

* The following JSON is sent in the request body.

* {
*     "UserPoolId": "us-west-2_yt6WzO3SA"
