Each request you submit must include credentials that can be authenticated, and the user account must have access to the Web Services feature on its default role. The Dayforce REST services use the HTTP basic authentication protocol for passing credentials.
Note: Some third-party REST client APIs don’t include the credentials on requests that result from a redirect response from the server. If you are receiving a 401 Unauthorized response, it might be due to this limitation. In the sample code, we use the RestSharp third party component for a REST client and we have implemented an IAuthenticator, which will pass the credentials on every request.
