Usage

This PayFast SDK requires config variables passed to it.

merchantId and passPhrase are mandatory, if not defined other fields will default to values shown below:

$config = [
    'merchantId' => 'testId',               // Required
    'passPhrase' => 'testPhrase',           // Required
    'endpoint' => '//api.payfast.co.za',
    'port' => 443,
    'ssl' => true,
    'testing' => false,
];

$payfast = new PayFastSDK($config);

Custom Requests

You can create a request to any endpoint in PayFast using $payfast->request->customRequest($verb, $method, $options)

For example, getting Transaction History

$verb = 'GET';
$method = '/history';
$options = [
    'from' => '2018-02-01',
    'to' => '2018-03-04',
];
$response = $payfast->request->customRequest($verb, $method, $options)

Quirks

Signature Generation

Payfast requires a MD5 hash of the alphabetised submitted variables, header and body variables, as well as the passphrase to ensure the request has not been tampered with.

Testing

Payfast provides a sandbox environment to test integrations.

Test requests are sent to the normal endpoint, but append ?testing=true to the URI.
