README

PHP wrapper for Przelewy24.

If you are using Laravel, check out dominservice/przelewy24-laravel.

Przelewy24's API documentation is available at https://developers.przelewy24.pl/.

The library was copied to implement payment card support from dbojdo.

Requirements

PHP >=8.1

Installation

composer require dominservice/przelewy24-php

Usage

Creating an instance

use Przelewy24\Przelewy24;

$przelewy24 = new Przelewy24(
    merchantId: 12345,
    reportsKey: 'f0ae...',
    crc: 'aef0...',
    isLive: false,
);

Setting isLive to false will use the sandbox environment. Set it to true to use production/live mode.

Creating a transaction

$transaction = $przelewy24->transactions()->register(
    // Required parameters:
    sessionId: 'unique order identifier from your application',
    amount: 125,
    description: 'transaction description',
    email: 'buyer email address',
    urlReturn: 'url to return to after transaction',

    // Optional parameters:
    urlStatus: 'url to which the transaction status webhook will be sent',

    // client: 'Mateusz Domin',
    // currency: \Przelewy24\Enums\Currency::EUR,
    // language: Language::POLISH,
    // ...
);

Note that amount is passed as an integer, so if the actual amount is 1.25 PLN you will need to pass 125 as value.

For the complete list of available parameters check the signature of TransactionRequests::register().

Return the transaction's token:

$transaction->token();

Return the URL to the payment gateway:

$transaction->gatewayUrl();

Listening for transaction status webhook

To parse the webhook's payload, pass the whole request's POST data as an array to handleWebhook():

// $requestData = $request->request->all();
// $requestData = $request->post();
// $requestData = json_decode(file_get_contents('php://input'), true);

$webhook = $przelewy24->handleWebhook($requestData);

handleWebhook() returns TransactionStatusNotification::class, which has a bunch of useful methods you can use to check the transaction's data, as well as verify the webhook's signature:

$webhook->amount();
$webhook->currency();
$webhook->orderId();
...
$webhook->isSignValid(...);

If you would like to make sure the incoming request's IP address belongs to Przelewy24 then a list of valid IPs is available in the \Przelewy24\Constants\IpAddresses::V4 constant. A helper method that accepts a string with an IP address and returns a boolean is also available: \Przelewy24\Constants\IpAddresses::isValid($ip).

Verifying a transaction

$przelewy24->transactions()->verify(
    sessionId: 'unique order identifier from your application',
    orderId: $webhook->orderId(),
    amount: 125,
);

Similarly to registering a transaction, the amount is passed as an integer.

Error handling

Should Przelewy24's API return an erroneous response, an ApiResponseException::class (which extends Przelewy24Exception::class) will be thrown. You can therefore use a try/catch block to handle any errors:

use Przelewy24\Exceptions\Przelewy24Exception;

try {
    $przelewy24->transactions()->verify([
        // ...
    ]);
} catch (Przelewy24Exception $e) {
    // Handle the error...
}
