How can I have both sum and groupby in a single aggregation Elasticsearch?

Elastic Stack Elasticsearch
1

I'm able to send HTTP POST requests individually for sum & groupby using aggs in order to filter data from the index which I created through logstash.

This is how I tried querying for groupby:

    "aggs":{  
      "total":{  
         "terms":{  
            "field":"responsecode"
         },
         "aggs":{  
            "grades_count":{  
               "value_count":{  
                  "script":"Integer.parseInt(doc['responsecode'].value)"
               }
            }
         }
      }
   }

And this is how I tried querying for sum:

"aggs":{  
      "total":{  
         "terms":{  
            "field":"userid"
         },
         "aggs":{  
            "grades_count":{  
               "value_count":{  
                  "script":"doc['userid'].value"
               }
            }
         }
      }
   }

So what I need now is to have both of them in a single aggs so that I can get both the sum and the group by results.

This is the MySQL query which i'm trying to apply it in elasticsearch:

select userId, sum(chargeAmount+0) from sb_api_response_summary where group by userId;

Where am i going wrong? Any help could be appreciated.
