Replicate Zoho Sign UI in Deluge script

Replicate Zoho Sign UI in Deluge script

I'm trying to write a Deluge function for sending document sign link via SMS


With my current deluge script, I can get the sing link delivered by email, no SMS
  1. info zoho.currenttime.addHour(17);
  2. deal = zoho.crm.getRecordById("Deals",id);
  3. account = zoho.crm.getRecordById("Accounts",deal.get("Account_Name").get("id"));
  4. contact = zoho.crm.getRecordById("Contacts",deal.get("Contact_Name").get("id"));
  5. documentid = "9ovp116285db24942421486c5f3db4f382077";
  6. url = "https://zohoapis.com/writer/api/v1/documents/" + documentid + "/merge/sign";
  7. // change to data merge sign
  8. fields = Map();
  9. fields.put("Account_Name.Account_Name",account.get("Account_Name"));
  10. fields.put("Account_Name.ACN",account.get("ACN"));
  11. fields.put("Account_Name.Billing_Street",account.get("Billing_Street"));
  12. fields.put("Account_Name.Billing_Street_2",account.get("Billing_Street_2"));
  13. fields.put("Account_Name.Billing_City",account.get("Billing_City"));
  14. fields.put("Account_Name.Billing_State",account.get("Billing_State"));
  15. fields.put("Account_Name.Billing_Code",account.get("Billing_Code"));
  16. fields.put("Account_Name.ABN",account.get("ABN"));
  17. fields.put("Account_Name.Trading_Name",account.get("Trading_Name"));
  18. fields.put("Account_Name.Trustee_Name",account.get("Trustee_Name"));
  19. fields.put("Director_1_Name",deal.get("Director_1_Name"));
  20. fields.put("Currency_Code",deal.get("Currency_Code"));
  21. fields.put("Amount",deal.get("Amount"));
  22. data = Map();
  23. data.put("data",fields);
  24. params = Map();
  25. signerList = List();
  26. signerObj1 = Map();
  27. signerObj1.put("recipient_1","vit@lend.com.au");
  28. signerObj1.put("action_type","sign");

  30. signerObj1.put("recipient1_countrycode","+61");
  31. signerObj1.put("recipient1_phonenumber","123456789");
  32. signerObj1.put("language","en");
  33. signerList.add(signerObj1);
  34. params.put("signer_data",signerList);
  35. params.put("merge_data",data);
  36. params.put("service_name","zohosign");
  37. params.put("filename","Account Terms - " + deal.get("App_ID") + " - " + account.get("Account_Name"));
  38. documentObj = invokeurl
  39. [
  40. url :url
  41. type :POST
  42. parameters:params
  43. connection:"newzohosignconn"
  44. ];
  45. info "documentObj :";
  46. info documentObj;

There is no even an option like in UI "Email" or "Email+SMS", I don't know if that is even possible in the Deluge script. The documentation doesn't explain anything
