PHP SDK Installation and Usage

Install via Composer

To install the PHP SDK from the Central Composer repository use composer:

composer require centarro/kco_rest

Highly recommended to use version tag when installing SDK.

composer require centarro/kco_rest:1.2.3.4

Detailed information about the PHP SDK package and a list of available versions can be found here: https://packagist.org/packages/klarna/kco_rest

Include the SDK into your PHP file using the Composer autoloader:

<?php

require('vendor/autoload.php');

Manual installation

To install the PHP SDK manually you need to clone the repo to any folder on your machine:

git clone [e-mail]:centarro/kco_rest_php.git /path/to/some/folder/kco_rest_php

Include the SDK into your PHP file using the SDK autoloader:

<?php

require('/path/to/some/folder/kco_rest_php/src/autoload.php');

⚠️Warning: Using manually installed SDK requires you to use the CURLTransport instance to send HTTP requests.

Documentation and Examples

Klarna API documentation: https://developers.klarna.com/api/
SDK References: https://klarna.github.io/kco_rest_php/

Example files can be found in the docs/ directory.
Additional documentation can be found at https://developers.klarna.com.

Logging and Debugging

PHP SDK logs information to STDOUT/STDERR. To enable debug mode, set DEBUG_SDK environment variable:

$ DEBUG_SDK=true php <your_program.php>

or

$ export DEBUG_SDK=1
$ php <your_program.php>

Another way to enable Debugging Mode is define the DEBUG_SDK inside your script:

<?php
// some code here
define('DEBUG_SDK', true);
// some code here

Be aware, the SDK just checks if the DEBUG_SDK is defined! It means you will see the debug information by using define('DEBUG_SDK', false); or export DEBUG_SDK=no

More information about the DEBUG_SDK flag can be found here: klarna#32

The output will look like:

DEBUG MODE: Request
