Omnipay: Paystack

Paystack driver for the Omnipay PHP payment processing library

Omnipay is a framework agnostic, multi-gateway payment processing library for PHP. This package implements Paystack support for Omnipay. https://paystack.com/ refer to the API docs here: http://developer.paystack.com/

Install

Via Composer

$ composer require oneafricamedia/omnipay-paystack

Basic Usage

Get the Paystack redirect URL

use Omnipay\Omnipay;

$url = Omnipay::create('Paystack')
    ->setCredentials(
        'your_key', 
        'your_secret'
    )
    ->setCallbackUrl('https://example.com/callback')
    ->getUrl(
        'test@example.com',
        'my_reference',
        'description',
        100
    );

Check transaction status (from the Paystack ipn)

1. Configure & setup an endpoint to receive the ipn message from Paystack
2. Listen for the message and use getTransactionStatus (please handle the http GET vars accordingly)

use Omnipay\Omnipay;

$status = Omnipay::create('Paystack')
    ->setCredentials(
        'your_key', 
        'your_secret'
    )
    ->getTransactionStatus(
        $_GET['paystack_notification_type'],
        $_GET['paystack_transaction_tracking_id'],
        $_GET['paystack_merchant_reference']
    );

3. $status will be either PENDING, COMPLETED, FAILED or INVALID. Handle these statuses in your application workflow accordingly.

TODO

1. Test coverage
