I have a requirement where I have to assign the Contact to the Account Contact Roles as the primary contact,whenever a lead is converted.

But I am not sure how it will be achieved? If it is going to be achieved with the help of a trigger,then on what object should I use the trigger,since lead object gets destroyed after getting converted to Account,Contact & Opportunity.

Please Help.


You have to use Database.LeadConvert for converted leads.So i share some code related to auto convert a lead when Lead status = webform. Customize based on your requirements.

trigger AutoConverter on Lead (after insert) {
 LeadStatus convertStatus = [
      select MasterLabel
      from LeadStatus
      where IsConverted = true
      limit 1
 List<Database.LeadConvert> leadConverts = new List<Database.LeadConvert>();

 for (Lead lead: Trigger.new) {
      if (!lead.isConverted && lead.WebForm__c == 'Free Trial') {
           Database.LeadConvert lc = new Database.LeadConvert();
           String oppName = lead.Name;



 if (!leadConverts.isEmpty()) {
      List<Database.LeadConvertResult> lcr = Database.convertLead(leadConverts);


If you face any issues let me know @Shobhit Saxena

  • -1, you clearly did not read the question. OP was not asking how to convert a lead programmatically

Thanks for giving your suggestions @All. Finally I got my task done.Following is the piece of code that worked for me:

trigger PopulateContactRoleOnConversion on Lead (before update) 
    PopulateContactRoleOnConversionHandler obj1=new PopulateContactRoleOnConversionHandler ();    //Creating an object of Handler class.
    obj1.onBeforeUpdate(trigger.new);    //Calling the Handler class method


The Handler class :

public with sharing class PopulateContactRoleOnConversionHandler 
    public void onBeforeUpdate(List<Lead> lstLeads)
        Map<Id,String> leadAccountStatus = new Map<Id,String>(); // Map of the converted AccountID and the Lead Status
        //Map<Id,String> leadContactStatus = new Map<Id,String>(); // Map of the converted ContactID and the Lead Status
        for(Lead lead :lstLeads) 
              if (lead.IsConverted)


        List<Account> lstAccounts = [SELECT Id from Account WHERE Id IN :leadAccountStatus.keySet()];

        for ( Account acc : lstAccounts) 
              Contact con=[SELECT Id,Phone,Email FROM Contact where Account.ID =:acc.ID];
              AccountContactRole objAccountContactRole=new AccountContactRole();
              objAccountContactRole.Role='Business User';
              insert objAccountContactRole;
