workspace_idstring

The ID of the workspace you plan to create the study in.

Include this to get a cost that matches what that workspace will be charged. The workspace's fee percentage, VAT rate and currency are used. If omitted, the fee percentage and VAT rate on your own account are used instead. These can differ from the workspace's rates, so the estimate may not match the cost of a study created in that workspace.
