[eok8177]

in My projects -> Project -> Sofort -> Options -> Test mode: -> Set checked

run this code:

    $configkey = env('SOFORT_API_KEY');

    $SofortLibPaycode = new Paycode($configkey);

    $SofortLibPaycode->setAmount(1.00)
       ->setLanguageCode('de')
        ->setCurrencyCode('EUR')
        ->setReason('sofort.com - Test', '8fb8400661')
        ->setSuccessUrl('http://lvh.me:8000/success')
        ->setSuccessLinkRedirect(1)
        ->setAbortUrl('http://lvh.me:8000/abort')
        ->setNotificationUrl('http://lvh.me:8000/notify')

    $SofortLibPaycode->createPaycode();
