PostFinance e-payment helper class
==================================

[](#postfinance-e-payment-helper-class)

This class helps to implement basic e-commerce features from PostFinance Switzerland. The implementation follows the [official documentation](https://e-payment.postfinance.ch/Ncol/PostFinance_e-Com-BAS_DE.pdf).

Install it
----------

[](#install-it)

```
composer require 'offline/postfinance'

```

Use it
------

[](#use-it)

See `index.php` for an example.

Define your parameters as an array. Get your SHA-IN signature at hand. Initialize a class instance and pass your parameter array to `setParamList`.

```
$shaInSignature = 'Configuration -> Technical information -> Data and origni verification -> SHA-IN pass phrase';
$params = [
    'PSPID'        => 'your-postfinance-username',
    'ORDERID'      => '1234',
    'AMOUNT'       => '200' * 100,
    'CURRENCY'     => 'CHF',
    'LANGUAGE'     => 'de_CH',
];

$postfinance = new Offline\PaymentGateways\PostFinance($shaInSignature);
$postfinance->setParamList($params);
```

In your view file call `getFormFields` wherever you want to output the hidden input fields.

```

```

### Using different algorithms

[](#using-different-algorithms)

To use SHA256 or SHA512 algorithms, simply pass the php MHASH constant as second parameter:

```
$postfinance256 = new Offline\PaymentGateways\PostFinance($shaInSignature, 'sha256');
$postfinance512 = new Offline\PaymentGateways\PostFinance($shaInSignature, 'sha512');
```

### Validating SHA-OUT signatures

[](#validating-sha-out-signatures)

Make sure you have the option `I would like to receive transaction feedback parameters on the redirection URLs.` under `Transaktion feedback` enabled.

```
$shaOutSignature = 'Configuration -> Transaction feedback -> SHA-OUT pass phrase';
$shaSign = isset($_GET['SHASIGN']) ? $_GET['SHASIGN'] : '';

$postfinance = new PostFinance($shaOutSignature);
$postfinance->setParamList($_GET);

$isValid = $postfinance->getDigest() === $shaSign;

var_dump($isValid);
```
