How to process a refund with Omnipay - NAB Transact - php

Question

I am trying to do the refund process and it is connected to the nab test mode server but not processing the refund transaction.
I did a transaction yesterday and wanted to refund the part money but it is not going through and shows the error that Credit card details not available (Error Code 133).
I am sending the request using TransactionID and TransactionReference and the amount to be deducted but not working.
My code:-
public function pay()
{
$gateway = Omnipay::create('NABTransact_SecureXML');
$gateway->setMerchantId('XYZ0010');
$gateway->setTransactionPassword('abcd1234');
$gateway->setTestMode(true);
$card = new CreditCard([
'firstName' => 'ABC',
'lastName' => 'DEF',
'number' => '4444333322221111',
'expiryMonth' => '05',
'expiryYear' => '2025',
'cvv' => '123',
]
);
$transaction = $gateway->purchase([
'amount' => '5000.00',
'currency' => 'AUD',
'transactionId' => '100321', // (My order ID)
'card' => $card,
]
);
$response = $transaction->send();
}
The transactionID i got here is: 706256
please view the screenshot for the above transaction in the NAB:
public function refund()
{
$gateway = Omnipay::create('NABTransact_SecureXML');
$gateway->setMerchantId('XYZ0010');
$gateway->setTransactionPassword('abcd1234');
$gateway->setTestMode(true);
$card = ([
'firstName' => 'ABC',
'lastName' => 'DEF',
'number' => '4444333322221111',
'expiryMonth' => '05',
'expiryYear' => '2025',
'cvv' => '123',
]
);
$refund = $gateway->refund([
'transactionReference' => "706256",
'amount' => "5.00",
'currency' => "AUD",
'transactionId' => "100321",
'messageID' => '4',
'card' => $card,
]);
$refund->send();
}

Answer 1

yes, i had solved it.
this is the sample of my code:
$gateway = Omnipay::create('NABTransact_SecureXML');
gateway->setMerchantId('_ID_');
$gateway->setTransactionPassword('_PASSWORD_');
$gateway->setTestMode(false);
$refund = $gateway->refund([
'transactionReference' => "12345",
'amount' => "500",
'transactionId' => 765897, (hope u must have saved this number in DB)
]);
$response = $refund->send();
$message = $response->getMessage();
if ($response->isSuccessful()) {
return "I m Happy"
} else {
return back()->with('amountError', $message);
}
Let me know how did it go :)
