I have noticed it is possible to send a URL of:

http://10.10.2.52:8080/sdpapi/technician?OPERATION_NAME=GET_ALL&TECHNICIAN_KEY=XXX&INPUT_DATA=<Details><siteName></siteName><groupid>4</groupid></Details>

i.e. without specifying a siteName.

Does ServiceDesk plus use the same groupId for different sites?  Or are they likely to be unique across the entire installation?

For example:

Melbourne hardware = 4

Melbourne software = 5

(Re-used group ids for different site)

Perth hardware = 4

Perth software = 5

or

(Unique group ids amongst all sites)

Perth hardware = 6

Perth hardware = 7

Many thanks,

Peter.
