Installation

Using Composer (recommended)

If you do not have Composer installed, please visit https://getcomposer.org/download/ for installation instructions.

Add Payrexx SDK to your project via Composer:

composer require payrexx/payrexx

Alternatively, add this to your composer.json and run composer update:

• For the latest development version:

  {
    "require": {
      "payrexx/payrexx": "dev-master"
    }
  }
  

• For the stable version 2.0.0:

  {
    "require": {
      "payrexx/payrexx": "2.0.0"
    }
  }
  

This will install the SDK and generate the necessary autoload files.

Quick Start

1. Instantiate the Payrexx client

   $instance = 'your-instance-name'; // e.g., 'demo' for https://demo.payrexx.com
   $apiSecret = 'your-api-secret';   // Find this in your Payrexx instance admin panel
   
   $payrexx = new \Payrexx\Payrexx($instance, $apiSecret);
   

2. Create a model object For example, to work with subscriptions:

   use Payrexx\Models\Request\Subscription;
   
   $subscription = new Subscription();
   $subscription->setId(1);
   

3. Call API methods

   For example, to cancel a subscription:

   try {
       $response = $payrexx->cancel($subscription);
       $subscriptionId = $response->getId();
   } catch (\Payrexx\PayrexxException $e) {
       // Handle errors
       echo 'Error Code: ' . $e->getCode() . PHP_EOL;
       echo 'Error Message: ' . $e->getMessage() . PHP_EOL;
   }
   

Specifying the API Version

The Payrexx PHP SDK constructor supports an optional $version parameter that allows you to specify the API version you want to use.

$instance = 'your-instance-name';
$apiSecret = 'your-api-secret';

// Specify the API version explicitly (e.g., "1.8")
$apiVersion = '1.8';

$payrexx = new \Payrexx\Payrexx(
    $instance,
    $apiSecret,
    \Payrexx\Communicator::DEFAULT_COMMUNICATION_HANDLER,
    '',           // leave empty if not using a custom API base domain
    $apiVersion   // specify the API version here
);

Using Platform Accounts (Custom API Base URL)

If you are working with Platform accounts, you must specify a custom API base domain when instantiating the client.

use Payrexx\Communicator;

$apiBaseDomain = 'your.domain.com';

$payrexx = new \Payrexx\Payrexx(
    $instance, 
    $apiSecret, 
    Communicator::DEFAULT_COMMUNICATION_HANDLER,
    $apiBaseDomain
);

Notes:

• $instance is the subdomain part of your unique domain.
• For example, if your login domain is client.platform.yourcompany.com, then:
  • $instance = 'client'
  • $apiBaseDomain = 'platform.yourcompany.com'
