Hi Karl,
There’s 2 different ways to you can get the ID’s, the recommended way to get the ID’s if your Converse System is on a version that supports the Groups API.
If you call: https://hostname/api/liberty/2/partitions/{partitonId}/acd/groups
That will return a list of all the groups for the requested partition, along with the Group ID, the Queues for each group and all Skills.
If you don’t have access to the Groups API, the unpleasant way would be to look in the URL for the ID’s requried.
For example to get the Group ID:
To get the Queue ID:

However, you can’t get the Skill ID from the URL.
I highly recommend you use the Groups API to get the IDs as you want, as this makes future groups, queues and skills easier.
Hope this helps!
