I have tried adding the Service Reference to my Project but this is not working?
https://api-eu.dhl.com/tracking
I am getting the following error when trying to add the Service Reference
Metadata contains a reference that cannot be resolved: 'https://api-eu.dhl.com/tracking'.The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was ''.The remote server returned an error: (401) Unauthorized.If the service is defined in the current solution, try building the solution and adding the service reference again.
