Fixed the issue: The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'NTLM'



Solution:

Make this change to your binding in web.config file 

 <binding name="BasicHttpBinding_ISPWebUsage2">
          <security mode="TransportCredentialOnly">
            <transport clientCredentialType="Ntlm" proxyCredentialType="None"
                realm="" />
                       <message clientCredentialType="UserName" algorithmSuite="Default" />
          </security>
        </binding>

Also  make sure you have the same binding in endpoint 

<client>
<endpoint address="http://abcdefgh/_vti_bin/service1/service.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ISPWebUsage2" contract="ServiceReference1.ISPWebUsage" name="BasicHttpBinding_ISPWebUsage2" />
    </client>

this should fix it

The first approach involves authenticating a SharePoint user, in which case your application has the same access to SharePoint data and capabilities as the user. The different ways you can authenticate a user from a Web or mobile application are outside the scope of this article, but we’ll briefly mention two new options in SharePoint 2013 because they affect the way you construct your REST requests: If you’re calling into SharePoint from a remotely hosted application that can’t use client-side code (HTML and JavaScript) exclusively, and there’s no firewall between SharePoint and your application, you can use OAuth 2.0 tokens with Microsoft Access Control Service (ACS) as the secure token server. If client-side ...
