Hi All,

Hope you could assist me modifying a code or adding a new one. I currently have email services that creates an Opportunity.  I am not really a coder, I am just looking around how to get this done.

My goal is that when user send an email from that Opportunity record (generated from Email services) and customer replies back (with threadId generated initially), the response of the customer should be attached to existing Opportunity. How can I achieve that? Should I attach it to existing code that I have?

Here is my existing Code that generates Opportunity record:

global class OpportunityCreation implements Messaging.InboundEmailHandler {

  global Messaging.InboundEmailResult handleInboundEmail(Messaging.InboundEmail email,
    Messaging.InboundEnvelope envelope) {

     Messaging.InboundEmailResult result = new Messaging.InboundEmailresult();
     
     String fName = email.fromname.substring(0,email.fromname.indexOf(' '));
     String lName = email.fromname.substring(email.fromname.indexOf(' '));
     
     Contact vCon;
     for(Contact c: [Select Id, Name, Email, AccountId From Contact Where Email = :email.fromAddress Limit 1])
         vCon = c;
     if(vCon == null)
     {
        vCon = new Contact(
        FirstName = fName,
        LastName =  lName,
        Email = email.fromAddress);
        insert vCon;
     }   
     
     Opportunity opportunity = new Opportunity();
     opportunity.Name = email.Subject;
     opportunity.StageName = 'Prospecting';
     opportunity.CloseDate = Date.today();
     opportunity.Email_Body__c = email.plainTextBody;
     opportunity.Contact_Name__c = vCon.Id;
     opportunity.AccountId = vCon.AccountId;
     insert opportunity;
    
       System.debug('====> Created opportunity '+opportunity.Id);
       
      
if (email.binaryAttachments != null && email.binaryAttachments.size() > 0) {
      for (integer i = 0 ; i < email.binaryAttachments.size() ; i++) {
        Attachment attachment = new Attachment();
        // attach to the newly created opportunity record
        attachment.ParentId = opportunity.Id;
        attachment.Name = email.binaryAttachments[i].filename;
        attachment.Body = email.binaryAttachments[i].body;
        insert attachment;
      }
    }
  
    return result;

  }

}

Thank you in advance.
