LargePersonGroup - List
List all existing large person groups’s largePersonGroupId, name, userData and recognitionModel.
- Large person groups are stored in alphabetical order of largePersonGroupId.
- "start" parameter (string, optional) is a user-provided largePersonGroupId value that returned entries have larger ids by string comparison. "start" set to empty to indicate return from the first item.
- "top" parameter (int, optional) specifies the number of entries to return. A maximal of 1000 entries can be returned in one call. To fetch more, you can specify "start" with the last retuned entry’s Id of the current call.
"start=&top=" will return all 5 groups.
"start=&top=2" will return "group1", "group2".
"start=group2&top=3" will return "group3", "group4", "group5".
