Till Payments driver for the Omnipay PHP payment processing library

Omnipay is a framework agnostic, multi-gateway payment processing library for PHP 5.3+. This package implements eWAY support for Omnipay.

Till Payments was founded in 2012 with the primary focus of helping technology vendors and their customers streamline their payments acceptance and operations.

Installation

Omnipay is installed via Composer. To install, simply add it to your composer.json file:

{
    "require": {
        "visualr/omnipay-tillpayments": "~2.0"
    }
}

And run composer to update your dependencies:

$ curl -s http://getcomposer.org/installer | php
$ php composer.phar update

Basic Usage

For general usage instructions, please see the main Omnipay repository.

Initializing Gateway

// Create a gateway
$gateway = Omnipay::create('TillPayments');

// Initialise the gateway
$gateway->initialize(array(
    'apiKey' => 'your-api-key',
    'secretKey' => 'your-secret-key',
    'username' => 'your-username',
    'password' => 'your-password',
    'testMode'  => TRUE, // or FALSE when you are ready for live transactions
    'defaultMerchantTransactionIdPrefix'  => 'omnipay-', // prefix of the merchantTransactionId (optional)
));

Remember! You will have different API Key for different connectors

Purchase Transaction

This is called Debit on Till Documentation

try {
    // You need to define your own $formData array
    $card = new CreditCard($formData);
    
    $request = $gateway->purchase([
        'amount' => '10.00', // this represents $10.00
        'currency' => 'AUD',
        'card' => $card,
    ]);
    
    $response = $transaction->send();

    if ($response->isSuccessful()) {

        // Do stuff here
        // Use $response->getTransactionReference() to get transaction uuid

    } else {

        // Handle errors

    }

} catch (\Guzzle\Http\Exception\ClientErrorResponseException $e) {

    // Handle Exception Errors (use $e->getResponse()->getBody() to get JSON data)

} catch (\Exception $e) {

    // Handle Exception Errors (use $e->getMessage() to get data)

}

You can also pass transactionToken on the payload if you receive a token using Till Payment's payment.js

For more information about the payload, refer to: Till Payment Documentation

For more information about the card data, refer to: Omnipay Credit Card Documentation

Authorize Transaction

This is called Preauthorize on Till Documentation

A Preauthorize reserves the payment amount on the customer's payment instrument.

Depending on the payment method you have up to 7 days until you must Capture the transaction before the authorization expires.

try {
    // You need to define your own $formData array
    $card = new CreditCard($formData);
    
    $request = $gateway->authorize([
        'amount' => '10.00', // this represents $10.00
        'currency' => 'AUD',
        'card' => $card,
    ]);
    
    $response = $transaction->send();

    if ($response->isSuccessful()) {

        // Do stuff here
        // Use $response->getTransactionReference() to get transaction uuid

    } else {

        // Handle errors

    }

} catch (\Guzzle\Http\Exception\ClientErrorResponseException $e) {

    // Handle Exception Errors (use $e->getResponse()->getBody() to get JSON data)

} catch (\Exception $e) {

    // Handle Exception Errors (use $e->getMessage() to get data)

}

You can also pass transactionToken on the payload if you receive a token using Till Payment's payment.js

For more information about the card data, refer to: Omnipay Credit Card Documentation

Capture Transaction

A Capture completes the payment which was previously authorized with the Preauthorize method.

Depending on the payment method you can even capture only a partial amount of the authorized amount.

try {
    // You need to define your own $formData array
    $card = new CreditCard($formData);
    
    $request = $gateway->capture([
        'amount' => '10.00', // this represents $10.00
        'currency' => 'AUD',
        'card' => $card,
        'referenceUuid' => 'bcdef23456bcdef23456', // UUID / transaction reference of a preauthorize
    ]);
    
    $response = $transaction->send();

    if ($response->isSuccessful()) {

        // Do stuff here
        // Use $response->getTransactionReference() to get transaction uuid

    } else {

        // Handle errors

    }

} catch (\Guzzle\Http\Exception\ClientErrorResponseException $e) {

    // Handle Exception Errors (use $e->getResponse()->getBody() to get JSON data)

} catch (\Exception $e) {

    // Handle Exception Errors (use $e->getMessage() to get data)

}

        'currency' => 'AUD',
        'card' => $card,
        'returnUrl' => 'https://www.example.com/return', // optional
    ]);
    
    $response = $transaction->send();

    ]);
    
    $response = $transaction->send();

    if ($response->isSuccessful()) {

        // Do stuff here
        // Use $response->getTransactionReference() to get transaction uuid

    } else {

        // Handle errors

    $request = $gateway->deleteCard([
        'referenceUuid' => 'ccf0ddd790db9d7ef41b',
    ]);
    
    $response = $transaction->send();

Refund Transaction

A Refund reverses a payment which was previously performed with Debit or Capture.

The Payment Responses

Successful Response

For a successful responses, a reference will normally be generated, which can be used to capture or refund the transaction at a later date. The following methods are always available:

$response = $gateway->purchase([
    'amount' => '10.00', 
    'currency' => 'AUD', 
    'card' => $card
])->send();

$response->isSuccessful(); // is the response successful?
$response->isRedirect(); // is the response a redirect?
$response->getTransactionReference(); // a transaction uuid generated by the payment gateway
$response->getMessage(); // a message generated by the payment gateway

If you are going to implement refund and void, you will need to always save the transaction reference since it is often used as referenceUuid.

Redirect Response

After processing a payment, the cart should check whether the response requires a redirect, and if so, redirect accordingly:

$response = $gateway->purchase([
    'amount' => '10.00', 
    'currency' => 'AUD', 
    'card' => $card
])->send();

if ($response->isSuccessful()) {
    // payment is complete
} elseif ($response->isRedirect()) {
    $response->redirect(); // this will automatically forward the customer
} else {
    // not successful
}

The customer isn't automatically forwarded on, because often the cart or developer will want to customize the redirect method (or if payment processing is happening inside an AJAX call they will want to return JS to the browser instead).

To display your own redirect page, simply call getRedirectUrl() on the response, then display it accordingly:

$url = $response->getRedirectUrl();

Error Response

You can test for a successful response by calling isSuccessful() on the response object. If there was an error communicating with the gateway, or your request was obviously invalid, an exception will be thrown. In general, if the gateway does not throw an exception, but returns an unsuccessful response, it is a message you should display to the customer. If an exception is thrown, it is either a bug in your code (missing required fields), or a communication error with the gateway.

The simplest way is to wrap the entire request in a try-catch block.

try {

    $request = $gateway->refund([
        'amount'                => '1.25',
        'currency'              => 'AUD',
        'referenceUuid'         => '48bbd15cdf9e5b81985d',
    ]);
    
    $response = $transaction->send();

    if ($response->isSuccessful()) {

        // Do stuff here like marking order as complete

    } else {

        // Handle errors

    }

} catch (\Guzzle\Http\Exception\ClientErrorResponseException $e) {

    // Handle Exception Errors (use $e->getResponse()->getBody() to get JSON data)

} catch (\Exception $e) {

    // Handle Exception Errors (use $e->getMessage() to get data)

}
