+ *                      project IDs the value is `SENDER_ID@gcm.googleapis.com`.
+ *  @param messageID    The ID of the message. This is generated by the application. It
+ *                      must be unique for each message generated by this application.
+ *                      It allows error callbacks and debugging, to uniquely identify
+ *                      each message.
+ *  @param ttl          The time to live for the message. In case we aren't able to
+ *                      send the message before the TTL expires we will send you a
+ *                      callback. If 0, we'll attempt to send immediately and return
+ *                      an error if we're not connected.  Otherwise, the message will
+ *                      be queued.  As for server-side messages, we don't return an error
+ *                      if the message has been dropped because of TTL; this can happen
+ *                      on the server side, and it would require extra communication.
