Code examples
Please note that you can find more code examples in our API-files which you will find under Download API in the left menu.
The code examples have been divided into several steps. Click on the step you would like to see the code example.
1. Initialize and setup the Klarna instance
$k = new Klarna();
$k->config(
123456, // Merchant ID
'sharedSecret', // Shared Secret
KlarnaCountry::SE, // Country
KlarnaLanguage::SV, // Language
KlarnaCurrency::SEK, // Currency
Klarna::BETA, // Server
'json', // PClass Storage
'/srv/pclasses.json', // PClass Storage URI path
true, // SSL
true // Remote logging of response times of xmlrpc calls
);
2. Change the reservation
// Here you enter the reservation number you got from reserveAmount():
$rno = '123456';
try {
$result = $k->changeReservation(
$rno, // Reservation number
49.99, // Amount
KlarnaFlags::NEW_AMOUNT // Flag deciding if the amount is the new amount
// to reserve, or if it is to be added to the
// existing amount. (KlarnaFlags::ADD_AMOUNT)
);
// Reservation changed, proceed accordingly.
echo "Result: {$result}\n";
} catch (Exception $e) {
// Something went wrong or the reservation doesn't exist.
echo "{$e->getMessage()} (#{$e->getCode()})\n";
