Online Payments PHP SDK

Introduction

The PHP SDK helps you to communicate with the payment platform server API. Its primary features are:

convenient PHP wrapper around the API calls and responses:
- marshalls PHP request objects to HTTP requests
- unmarshalls HTTP responses to PHP response objects or PHP exceptions
handling of all the details concerning authentication
handling of required meta data

Its use is demonstrated by an example for most calls. The examples execute a call using the provided API keys.

This repository consists out of the following components:

The source code of the SDK itself: /src and /lib
The source code of the unit and integration tests (including the examples): /tests

PHP 7.4 or above is required.

Initialize Composer in your project, if this is not already done, by executing the following command:
```
composer init
```
Add a requirement to the SDK to your composer.json file by executing the following command:
```
composer require wl-online-payments-direct/sdk-php
```
Add vendor/autoload.php to your project, if this is not already done, by adding the following line of code:
```
require __DIR__ . '/vendor/autoload.php';
```

Download the latest version of the PHP SDK from GitHub. Choose the onlinepayments-sdk-php-x.y.z.tar.gz file from the releases page, where x.y.z is the version number.
Add the contents of the tar.gz file to your project. The content of the /src and /lib folders may be combined, if this is required by the project.
Add all classes from the /src and /lib folders to your autoloader; all classes inside these folders are compliant with PSR-4.

Install Composer
From the root of the sdk-php project, run composer install
Copy tests/config.json.dist to tests/config.json and replace the template values by actual values
From the root of the sdk-php project, vendor/phpunit/phpunit/phpunit (or just phpunit when it is already installed on your local machine)
