Get CRM ID for further fetching and update

Get CRM ID for further fetching and update

Hi,

I'm trying to get Campaign ID for CRM. What is the correct way to write Campaign Id to get ID for further update ? It's working with all fields but not ID... 

Thanks.

  2.     crmResp = zoho.crm.searchRecordsByPDC("Campaigns", "campaignname", input.Campagnes_Promotions);
  3.     for each r in crmResp
  4.     {
  5.         Budgeted = r.get(("Budgeted Cost"));
  6.         Actual = r.get("Actual Cost");
  7.         input.CampaignID = r.get("Campaign Id");
  8.     }
