+    
+    partial void InterceptRequest(IRestRequest request)
+    {
+        var signingKey = AuthenticationUtils.LoadSigningKey(SigningKeyPkcs12FilePath, SigningKeyAlias, SigningKeyPassword, X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.Exportable);
+        var signer = new RestSharpSigner(ConsumerKey, signingKey);
+        signer.Sign(new Uri(BaseServicePath), request);
