null response on getMessage()

[poxin13]

Using FirstData_Webservice, getting a null response on the transaction send.

        $card = Omnipay::creditCard($cardInput);

        $response = Omnipay::purchase([
            'amount'        => '100.00',
            'transactionId' => '100.00',
            'accountId'     => '100.00',
            'card'          => $cardInput
        ])->send();

        dd($response->getMessage());

I noticed the gateways are updated to TLS 1.2 only, perhaps this is the cause?

TLS1.2 Update: In order to adhere to the PCI mandate, the Gateways will update systems to support the TLS1.2 protocol only in January 2018. Please contact your sales representative for more information and steps required to ensure compliance.

The TLS 1.2 thing is almost certainly the issue. Can you check that your system is doing a TLS 1.2 connect? Depending on the version of OpenSSL or equivalent that you have, it may be necessary to set the TLS version explicitly.

I've been in contact with Firstdata about their API access, it appears some of the endpoints have been shutoff too. Even forcing TLS 1.2 in curl, etc - this would not connect using 'FirstData_Webservice'

Ended up writing my own with Guzzle using the only endpoint I could find that is still active, though according to them this will be sunset soon too.

Using version 1.1 of their API. Good enough for now until I just move to something else.

$response = $client->request('POST', 'https://secure.linkpt.net:1129/LSGSXML', [
    'cert'   => 'key.pem',
    'verify' => false,
    'body'   => $xml_data
]);
