Each data element that is returned from Dayforce REST Services might have an access authorization associated with it. The access authorization limits the data that can be returned. Access authorizations are hard-coded on the data contract and aren't customizable. The access authorizations used by Dayforce REST Services are the same as those used by the rest of the Dayforce application.
For example, many properties of the Employee class are controlled by the Employee Personal Information access authorization. If you add this access authorization on the default role of the user that was used during authentication, you can see properties such as names and dates.
