Swish-PHP is a small wrapper for the swish merchant api. See https://www.getswish.se/handel/ for more information.
- php 7.3 or newer with curl & openssl
- composer
- The function
createPaymentRequestnow returns an object with the two propertiesidandpaymentRequestToken. In earlier versions the id was returned directly.
git clone https://github.com/helmutschneider/swish-php.git
composer installcomposer require helmutschneider/swish-php:^3.0As of 2022-05-29, a test certificate bundle (mss_test_1.9.2.zip) can be found by visiting: https://developer.swish.nu/documentation/environments#certificates
Begin by obtaining the SSL certificates required by Swish. The Swish server itself uses a self-signed root certificated so a CA-bundle to verify its origin is needed. You will also need a client certificate and corresponding private key so the Swish server can identify you.
As of 2022-05-29 the test certificates are called Swish_Merchant_TestCertificate_1234679304.key, Swish Merchant Test Certificate 1231181189.pem and Swish_TLS_RootCA.pem.
You must concatenate Swish_Merchant_TestCertificate_1234679304.key and Swish Merchant Test Certificate 1231181189.pem together, otherwise they will not work with cURL.
This bundle is your client certificate.
The client closely mirrors the swish api:
class Client
{
/**
* @param PaymentRequest $request
* @return CreatePaymentRequestResponse
* @throws \GuzzleHttp\Exception\GuzzleException
* @throws ValidationException
*/
public function createPaymentRequest(PaymentRequest $request): CreatePaymentRequestResponse;
/**
* @param string $id Payment request id
* @return PaymentRequest
* @throws \GuzzleHttp\Exception\GuzzleException
*/
public function getPaymentRequest(string $id): PaymentRequest;
/**
* @param Refund $refund
* @return string refund id
* @throws \GuzzleHttp\Exception\GuzzleException
* @throws ValidationException
*/
public function createRefund(Refund $refund): string;
/**
* @param string $id Refund id
* @return Refund
* @throws \GuzzleHttp\Exception\GuzzleException
*/
public function getRefund(string $id): Refund;
}When you have the SSL certificates ready you may instantiate the client:
use HelmutSchneider\Swish\Client;
use HelmutSchneider\Swish\PaymentRequest;
// Swish CA root cert
$rootCert = 'path/to/swish-root.crt'; // forwarded to guzzle's "verify" option
// .pem-bundle containing your client cert and it's corresponding private key. forwarded to guzzle's "cert" option
// you may use an empty string for "password" if you are using the test certificates.
$clientCert = ['path/to/client-cert.pem', 'password'];
// Create a client for the production environment. To connect to the test environment
// instead, you must pass the constant Client::SWISH_TEST_URL as the third parameter.
$client = Client::make($rootCert, $clientCert);
$pr = new PaymentRequest([
'callbackUrl' => 'https://localhost/swish',
'payeePaymentReference' => '12345',
'payerAlias' => '4671234768',
'payeeAlias' => '1231181189',
'amount' => '100',
])
$res = $client->createPaymentRequest($pr);
var_dump($res->id);
//
// string(32) "0D3AD8F1AE484A57B82A87FAB8C602EB"
//The bundled PHP in OSX 10.12 and earlier is not compatible with the above approach of forwarding SSL certificates. You must obtain a PHP-version that is compiled with cURL linked against OpenSSL or similar.
To run the tests you need certificates for the Swish test server. Place the root certificate in tests/_data/root.pem and
the client certificate in tests/_data/client.pem.
