zoho books custom function with deluge - zoho

Question

I'm creating a custom function in zoho books that will create a record in zoho creator using payment record information from zoho books. I've been able to successfully create a record in zoho creator but I'm unable to get the invoice_id from the customer_payment map.
Unfortunately, there's no error being thrown.
Below is the code:
paymentMap = Map();
//set order to payment invoice id - this is not working
paymentMap.put("Order",customer_payment.get("invoices[0].invoice_id"));
paymentMap.put("Description",customer_payment.get("card_type"));
paymentMap.put("Payment_ZB_ID",customer_payment.get("payment_id"));
response = zoho.creator.createRecord("XXXXX","XX","Payment",paymentMap);
info response;
Below is the map that is available:

Answer 1

paymentMap.put("Order",customer_payment.get("invoices[0].invoice_id"));
Deluge does not throw an error here. Instead, when an element whose key is not available is being fetched, it throws a null.
The key used in ur code snippet invoices[0].invoice_id is not a valid key in the customer_payment map. So, this has been throwing a null value which would have populated as an empty (or no) value in Zoho Creator.
If you notice the customer_payment clearly, all invoices are available under the key "invoices".
invoices = customer_payment.get("invoices");// now invoices will have the list of invoices in customer_payment map
Assuming that the payment has only one invoice, the invoice ID can be extracted as below:
invoiceId = invoices.getJson("invoice_id");
It is also possible to extract the invoice ID as you have tried, like the below:
info customer_payment.get("invoices").get(0).get("invoice_id");

Answer 2

You can fetch invoice_id like this :
customer_payment = {"payment_id":"11111111111111111","payment_number":"1","payment_number_prefix":"","payment_number_suffix":"1","documents":{},"customer_id":"11111111111111111","customer_name":"John Doe","payment_mode":"Stripe","card_type":"visa","card_type_formatted":"Visa","date":"2019-03-04","date_formatted":"03/04/2019","account_id":"11111111111111111","account_name":"Stripe Clearing","account_type":"payment_clearing","account_type_formatted":"Payment Clearing Account","currency_id":"11111111111111111","currency_code":"USD","exchange_rate":1,"exchange_rate_formatted":"$1.00","amount":1,"amount_formatted":"$1.00","unused_amount":0,"unused_amount_formatted":"$0.00","bank_charges":0.33,"bank_charges_formatted":"$0.33","tax_account_id":"","is_client_review_settings_enabled":false,"tax_account_name":"","tax_amount_withheld":0,"tax_amount_withheld_formatted":"$0.00","discount_amount":0,"discount_amount_formatted":"$0.00","description":"Stripe processing fees : $0.33 ","reference_number":"12345","online_transaction_id":"12345","settlement_status":"","settlement_status_formatted":"","invoices":{{"invoice_number":"11111111111111111","invoice_payment_id":"11111111111111111","invoice_id":"11111111111111111","amount_applied":1,"amount_applied_formatted":"$1.00","tax_amount_withheld":0,"tax_amount_withheld_formatted":"$0.00","discount_amount":0,"discount_amount_formatted":"$0.00","total":1,"total_formatted":"$1.00","balance":0,"balance_formatted":"$0.00","date":"2019-03-04","date_formatted":"03/04/2019","due_date":"2019-03-04","due_date_formatted":"03/04/2019","price_precision":2,"apply_date":"","apply_date_formatted":""}},"payment_refunds":{},"last_four_digits":"1234","template_id":"11111111111111111","template_name":"Elite Template","page_width":"8.27in","page_height":"11.69in","orientation":"portrait","template_type":"elite","template_type_formatted":"Elite","attachment_name":"","can_send_in_mail":true,"can_send_payment_sms":false,"is_payment_details_required":true,"custom_fields":{},"custom_field_hash":{},"imported_transactions":{}};
invoices = customer_payment.getJson("invoices");
//info invoices;
invoiceId = invoices.getJSON("invoice_id");
info invoiceId;
