Basic Usage

Get the Paystack redirect URL

use Omnipay\Omnipay;

$pay = Omnipay::create('Paystack')
    ->setSecretKey('YOUR_SECRET_KEY');
    ->purchase([
            'amount' => 2000,
            'transactionId' => 'transId',
            'currency' => 'NGN',
            'cancelUrl' => 'https://canclecallback',
            'returnUrl' => 'https://yourcallback',
        ]);
if ($pay->isRedirect()) { 
   $pay->redirect(); //redirect to pay on paystack
}

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;

$status = Omnipay::create('Paystack')
    ->setSecretKey('YOUR_SECRET_KEY');
    ->completePurchase([
                'transactionId' => 'transId',
            ])
      ->send();
if ($status->isSuccessful()) {
    //give value to user
}

3. $status will be either paystack verify transaction object . Handle these statuses in your application workflow accordingly.
