Download and use a SDK for simple integration with our API.
The recommended way to install the SDK is to use composer. To add the SDK as a composer dependency to your project, run the following command in your project directory:
composer require "klarna/php-xmlrpc 5.0"
If your project does not support composer, you can either clone the project on GitHub or download the package from here. You will then have to manually add the library to your project.
