Service Userpoints : Missing required argument points My environment : Drupal 7 &amp; service 3.x

I use userpoints and service-userpoints. I want to CRUD userpoints.

So i create a xmlrpc server and test it by Postman from Chrome store.

The xml code is belowed:

&lt;?xml version='1.0' ?&gt;
&lt;methodCall&gt;
  &lt;methodName&gt;pointss.add&lt;/methodName&gt;
  &lt;params&gt;
    &lt;param&gt;
      &lt;value&gt;
        &lt;struct&gt;
          &lt;member&gt;
            &lt;name&gt;uid&lt;/name&gt;
            &lt;value&gt;
              &lt;int&gt;1&lt;/int&gt;
            &lt;/value&gt;
          &lt;/member&gt;
          &lt;member&gt;
            &lt;name&gt;points&lt;/name&gt;
            &lt;value&gt;
              &lt;int&gt;150&lt;/int&gt;
            &lt;/value&gt;
          &lt;/member&gt;
          &lt;member&gt;
            &lt;name&gt;description&lt;/name&gt;
            &lt;value&gt;
              &lt;string&gt;test for xmlrpc service&lt;/string&gt;
            &lt;/value&gt;
          &lt;/member&gt;
        &lt;/struct&gt;
      &lt;/value&gt;
    &lt;/param&gt;
  &lt;/params&gt;
&lt;/methodCall&gt;


"pointss" is my userpoints-api's alias

i connect successful but got the message belowed.

&lt;?xml version="1.0"?&gt;



    
        
            
                
                    faultCode
                    
                        401
                    
                
                
                    faultString
                    
                        Missing required argument points
                    
                
            
        
    


How can i fix my xml body?
Does anybody have experience?
Thanks a lot.
I finally get it.

The XMLRPC format is belowed:

&lt;?xml version="1.0"?&gt;
&lt;methodCall&gt;
   &lt;methodName&gt;pointss.addpoints&lt;/methodName&gt;
   &lt;params&gt;
     &lt;param&gt;
           &lt;name&gt;uid&lt;/name&gt;
           &lt;value&gt;&lt;int&gt;1&lt;/int&gt;&lt;/value&gt;
           &lt;name&gt;points&lt;/name&gt;
           &lt;value&gt;&lt;int&gt;150&lt;/int&gt;&lt;/value&gt;
           &lt;name&gt;tid&lt;/name&gt;
           &lt;value&gt;&lt;int&gt;18&lt;/int&gt;&lt;/value&gt;
           &lt;name&gt;operation&lt;/name&gt;
           &lt;value&gt;&lt;string&gt;test for operation&lt;/string&gt;&lt;/value&gt;
           &lt;name&gt;description&lt;/name&gt;
           &lt;value&gt;&lt;string&gt;test for description&lt;/string&gt;&lt;/value&gt;
           &lt;name&gt;entity_type&lt;/name&gt;
           &lt;value&gt;&lt;string&gt;node&lt;/string&gt;&lt;/value&gt;
           &lt;name&gt;entity_id&lt;/name&gt;
           &lt;value&gt;&lt;int&gt;1&lt;/int&gt;&lt;/value&gt;
     &lt;/param&gt;
   &lt;/params&gt;
&lt;/methodCall&gt;


If somebody use service3.x and userpoints service, i hope i can help you.
