This operation updates the list of blocked properties and includes. By default, users can access all properties and includes in a group, and this operation specifies IDs for any to block. To find out which each refers to, see Manage access to properties and includes. To get the list of already blocked properties run the List blocked properties and includes operation. In this request, include the whole list of properties you want to block. By not including a blocked property, you're unlocking it.
