Required permission: VariableReadGroup

After you create the VariableValueGroup, you can use the group ID to read the group like any other resource. For example, GET http://my_server:3580/nivariable/VariableValueGroups('1587dcd4a87d118ae3ddd0fce09246f6')?$format=json

To read the VariableValues contained in the group, you can request the deferred VariableValues URI:

GET http://my_server:3580/nivariable/VariableValueGroups('1587dcd4a87d118ae3ddd0fce09246f6')/VariableValues?$format=json

You can use the $expand option to include the VariableValues in the group response. For example, GET http://my_server:3580/nivariable/VariableValueGroups('1587dcd4a87d118ae3ddd0fce09246f6')?$expand=VariableValues&$format=json
