Getting WebEx room ID for sparkSend

[John Pfuntner]

My team has some Jenkins Groovy code that calls sparkSend to send messages to a Cisco WebEx messaging room.  The code always writes to the same room and the room ID is expressed as a UUID (8-4-4-4-12 format string).  I think this code has been around in WebEx's previous incarnation known as Spark.  When I use the WebEx API to get the IDs of all rooms I use (and potentially write Jenkins code to send a message to another room), the IDs are always a 76 character long string ([a-zA-Z0-9]{76}).

sparkSend seems to require a UUID and won't use the 76 character string.  Is there a way to take the 76 character string and derive the UUID that sparkSend likes?
