quickbooks api to add a payment against an invoice with RubyRails app - ruby-on-rails

Question

I am trying to mark an invoice mark as paid and as per my understanding I have to add a payment against the invoice. I am using qbwc gem and it is using qbxml v.13.
I have found out few examples of creating the payment object here https://community-intuit.force.com/developer/s/article/QBO-REST-Apply-payments-to-invoice but the qbxml tag for creating payment is not clear to me.
Here are few xml tags that I have found in OSR ReceivePaymentAddRq, ItemPaymentAddRq etc
But I am still not sure how to create the payment object and which xml tags should be used and help is appreciated, thanks in advance.

Answer 1

A minimal qbXML example looks like this:
<?xml version="1.0" encoding="utf-8"?>
<?qbxml version="10.0"?>
<QBXML>
<QBXMLMsgsRq onError="stopOnError">
<ReceivePaymentAddRq>
<ReceivePaymentAdd>
<CustomerRef>
<ListID>F230000-1196864585</ListID>
<!--<FullName>Keith Palmer</FullName>--> <!-- You can specify either ListID or FullName -->
</CustomerRef>
<TxnDate>2007-12-14</TxnDate>
<RefNumber>00612361</RefNumber>
<TotalAmount>195.00</TotalAmount>
<!-- Specify the Invoice TxnID here, or see below for auto-apply... -->
<AppliedToTxnAdd>
<TxnID>12006-1196864828</TxnID>
<PaymentAmount>195.00</PaymentAmount>
</AppliedToTxnAdd>
<!-- If you don't want to apply payments manually to a particular transaction, use <IsAutoApply>true</IsAutoApply> -->
<!-- instead of the <AppliedToTxn> node. QuickBooks will make it's best guess how to apply the payment. -->
</ReceivePaymentAdd>
</ReceivePaymentAddRq>
</QBXMLMsgsRq>
</QBXML>
