First I'd really recommend you use The library written by Keith Palmer for this as the QBO documentation is garbage that's all over the place.

With that being said:

You need to return the transaction Id from the invoice:

return $resultingObj->TxnId;

And then create a payment using supplying that transaction id:

$invoiceId = CreateInvoice(); //returns txnId above

$qbLinkedInvoice = new IPPLinkedTxn();
$qbLinkedInvoice->TxnId = $invoiceId;
$qbLinkedInvoice->TxnType = 'Invoice';

$qbLine = new IPPLine();
$qbLine->Amount = "";//set amount;
$qbLine->LinkedTxn = $qbLinkedInvoice;

$qbPayment = new IPPPayment();
$qbPayment->CustomerRef = "";//customer id
$qbPayment->TotalAmt = "";//I think this must match amount above;
$qbPayment->Line = array($qbLine);

$createdQbPayment = $this->dataService->Add($qbPayment);
