README

Documentation: https://kassa.com/help/

Requirements

PHP 5.5 and later.

Dependencies

The bindings require the following extensions in order to work properly:

• curl, although you can use your own non-cURL client if you prefer.
• json
• mbstring (Multibyte String)
• php-fig/log
• guzzlehttp/psr7

Optionally

• guzzlehttp/guzzle for use guzzle instead of cURL.

Composer

You can install the lib via Composer. Run the following command:

composer require kassacom/php-sdk

To use the bindings, use Composer's autoload:

require_once('vendor/autoload.php');

If you use Composer, these dependencies should be handled automatically.

Getting Started

We recommend using the GuzzleHttp Client

Init client

$guzzleClient = new GuzzleHttp\Client();
$transport = new KassaCom\SDK\Transport\GuzzleApiTransport($guzzleClient);
$client = new KassaCom\SDK\Client($transport);
$client->setAuth('login', 'secret'); // or for basic authorization $client->setAuth('login', 'password', KassaCom\SDK\Transport\Authorization\BasicAuthorization::class);

All requests are processed in similar steps:

1. Create request instance of KassaCom\SDK\Model\Request\AbstractRequest
2. Request serialization
3. Sending a request to the server
4. You have a response object instance of KassaCom\SDK\Model\Response\AbstractResponse or throws exception if request fail

All requests are creating by suitable objects or can be created on the basis of arrays, integers and strings

Create payment

Creating request with object

// Create a request object
$createPaymentRequest = new KassaCom\SDK\Model\Request\Payment\CreatePaymentRequest();

// Set up $createPaymentRequest with required params

    $createPaymentResponse = $client->createPayment($createPaymentRequest);
} catch (\Exception $e) {
    // ...
}

or you can create request with array

$requestArray = [
    'order' => [/*...*/],
    'settings' => [/*...*/],
    'custom_parameters' => [/*...*/],
    'receipt' => [/*...*/],
];

try {
    /** @var KassaCom\SDK\Model\Response\Payment\CreatePaymentResponse $createPaymentResponse */

Payouts report

Download report file

Exceptions

• KassaCom\SDK\Exception\TransportException - throws in the case of an api transport error. For example, when authorization data is not provided.
• KassaCom\SDK\Exception\JsonParseException - the server response doesn't contain a valid json.
• KassaCom\SDK\Exception\ServerResponse\ResponseException - 4xx and 5xx server errors.
• KassaCom\SDK\Exception\Response\ResponseParseException - create response errors.
• KassaCom\SDK\Exception\Request\RequestParseException - create request errors.

Processing notification from server

This code is responsible for processing the payment result. You need to create handler, make it available on URL in your application and specify the URL in the project settings in kassa.com. This handler will be called after the user makes a payment using the form on kassa.com

$notification = new Notification();
$notification->setApiKey('api-key');
$notification->process();

You can use manual response to server:

$notification->process(false);

// if success
$notification->successResponse();
// if error
$notification->errorResponse('Error message');

If you use a proxy server, you can skip the IP check

$notification->setSkipIpCheck();

Custom Api Transport

You can create your own api transport by extending KassaCom\SDK\Transport\AbstractApiTransport

class MyApiTransport extends AbstractApiTransport {
    protected function sendRequest(Psr7\Request $request) {
        // Implementing the sendRequest() method
    }
}
