Omnipay Netbanx issue with state & country errors

Question

I'm in the process of implementing Netbanx as a payment gateway using the Omnipay PHP library, but I'm having an issues with errors relating to "Node: state" and "Node: country" strings being less than the minLength facet.

Note: I'm using the test credentials provided to me when registering for a developer account at Netbanx, and test CC details listed in their documentation here: docs.

Here is a code snippet from my Payment class:

class NetbanxPayment
{
    /**
     * Initialize payment gateway.
     *
     * @param string $accountNumber
     * @param string $storeId
     * @param string $storePassword
     * @param bool   $testMode
     */
    public function __construct($accountNumber, $storeId, $storePassword, $testMode = false)
    {
        $omnipay = new Omnipay;

        $this->gateway = $omnipay->create('NetBanx');

        $this->gateway->setAccountNumber($accountNumber);
        $this->gateway->setStoreId($storeId);
        $this->gateway->setStorePassword($storePassword);
        $this->gateway->setTestMode($testMode);
    }

    /**
     * Handle making the purchase
     *
     * @param       $amount
     * @param array $data
     *
     * @return \AwardForce\Modules\Payments\Contracts\Response
     */
    public function purchase($amount, $data = [])
    {
        $card = new CreditCard();

        $card->setNumber(array_get($data, 'cardNumber', ''));
        $card->setExpiryMonth(array_get($data, 'expiryMonth', ''));
        $card->setExpiryYear(array_get($data, 'expiryYear', ''));
        $card->setCvv(array_get($data, 'cvv', null));
        $card->setBillingAddress1(array_get($data, 'street', ''));
        $card->setBillingCity(array_get($data, 'city', ''));
        $card->setBillingPostcode(array_get($data, 'postcode', ''));
        if (array_get($data, 'country', '') == 'US') {
            $card->setBillingState(array_get($data, 'region', ''));
        }
        $card->setBillingCountry(array_get($data, 'country', ''));

        $response = $this->gateway->purchase([
            'amount'   => $amount,
            'currency' => $this->getCurrency(),
            'card'     => $card
        ])->send();

        dd($response);
     }
}

Here is the dumped response with the errors I'm seeing:

        <zip>1234</zip>

    </billingDetails>

Any help, advice or pointers in the right direction as to what might be causing these issues would be greatly appreciated :)

Answer 1

So after having a look at the developer docs for Netbanx it seems it's not expecting the billing state and country to be part of the card object.

    "card" => CreditCard {#1094 ▼
      #parameters: ParameterBag {#1342 ▼
        #parameters: array:7 [▼
          "number" => "4530910000012345"
          "expiryMonth" => 11
          "expiryYear" => 2019
          "cvv" => "123"
          "billingPostcode" => "1234"
          "billingState" => "London"
          "billingCountry" => "GB"
        ]
      }

https://developer.optimalpayments.com/en/documentation/card-payments-api/card-object/

The API is expecting a request like this:

     "merchantRefNum" : "demo-1",
     "amount" : 10098,
     "settleWithAuth":true,
     "card" : {
       "cardNum" : "4111111111111111",
       "cardExpiry":{
         "month":2,
         "year":2017
        },
        "cvv":123
      },
      "billingDetails":{
         "street":"100 Queen Street West",
         "city":"Toronto",
         "state":"ON",              
         "country":"CA",
         "zip":"M5H 2N2"
      }
    } '

It's probably a problem with the Omnipay plugin, but you're going to have to modify it so that the billing details are sent in the correct object.
