How to call WCF Rest service with Basic Auth using Postman? - wcf

Question

I have created a WCF service with Basic Authentication following this article https://learn.microsoft.com/en-gb/dotnet/framework/wcf/feature-details/transport-security-with-basic-authentication.
But when I call it using Postman, I get an error (400 Bad Request).
If I use a small application written in C# setting out ClientCredentials, it works well.
Here is my server code:
public class DataService : IDataService
{
public bool GetData()
{
return true;
}
}
[ServiceContract]
public interface IDataService
{
[OperationContract]
[WebInvoke(Method = "GET", UriTemplate = "GetData")]
bool GetData();
}

</service>
</services>

</configuration>
I also turned off "SSL certificate verification" and proxy in Postman
