Hi,

I'm wanting to remove currency, ID, and recordtypeid from my JSON file but I can't seem to find a way to remove them from the JSON file, Can someone advise where / What I need to be looking at to. Please see the code below.
 

public class JsonGenDispositionData {
    
    public String jsonString {set;get;}
    
    public static void gatherDispositionData(){
            
        List<stage_tracker__c> dispositionDataToSend = [SELECT Distribution_id__c,contact_status__c FROM Stage_Tracker__c WHERE Distribution_id__c != null LIMIT 3];
        List<Stage_tracker__c> payload = new list <Stage_Tracker__c>();
        
        // system.debug('Stage Trackers' + dispositionDataToSend);
        
        If(dispositionDataToSend.isempty()==false){
            JSONGenerator gen = JSON.createGenerator(true);
            for(Stage_Tracker__c ST : dispositionDataToSend){
                gen.writeStartArray();
                gen.writeStartObject();
                gen.writeStringField('DISTRIBUTION_ID', ST.Distribution_Id__c);
                gen.writeBooleanField('CONTACT_STATUS', ST.contact_status__c);
                gen.writeEndObject();
                gen.writeEndArray();
                payload.add(ST); 
            }
        }
        
        string jsonString = JSON.serialize(payload);
        system.debug(jsonString);
    }
    
}

My currnet output:
 

[{"attributes":{"type":"Stage_Tracker__c","url":"/services/data/v53.0/sobjects/Stage_Tracker__c/a5i3z000000UKNZAA4"},
"Distribution_Id__c":"8056fec2-b009-2cde-2d98-5f9ad4",
"contact_status__c":true,
"Id":"a5i3z000000UKNZAA4",
"RecordTypeId":"0123z000000gHwCAAU",
"CurrencyIsoCode":"GBP"}]

 I dont need the last 3 lines, (Id / RecordTypeId / CurrencyIsoCode)

How can I remove them.

Also any general code improvments would be welcomed.

Thanks
