Swisscom Easypay

A PHP library to manage payments with Swisscom Easypay.

Installation

Install the library with composer:

composer require gridonic/swisscom-easypay

Basic Usage

Note: This guide only covers the basics on how to use this library. More details about Easypay can be found in the official documentations.

Environment

Create a new STAGING or PROD environment based on your credentials:

use Gridonic\EasyPay\Environment\Environment;

$prodEnvironment = new Environment(Environment::ENV_PROD, 'my-merchant-id', 'my-secret-key')
$stagingEnvironment = new Environment(Environment::ENV_STAGING, 'my-merchant-id', 'my-secret-key')

Checkout page

Redirect the user to the Easypay checkout page where the purchase must be confirmed.

1. Map the user's shopping cart to a CheckoutPageItem. Note that you must provide the success/error/cancel urls for the redirect back to your shop.
2. In case of a recurrent service, make sure to pass the duration and duration unit to the checkout page item via setDuration() and setDurationUnit().
3. Call CheckoutPageService::getCheckoutPageUrl() to obtain the redirect url.

use Gridonic\EasyPay\CheckoutPage\CheckoutPageItem;
use Gridonic\EasyPay\CheckoutPage\CheckoutPageService;

// Map the user's shopping cart to a CheckoutPageItem
$checkoutPageItem = new CheckoutPageItem();
$checkoutPageItem
    ->setTitle('A mandatory title displayed on the checkout page')
    ->setDescription('A mandatory description displayed on the checkout page')
    ->setPaymentInfo('Mandatory payment information, visible on the invoice of the customer')
    ->setAmount('99.90')
    ->setSuccessUrl('https://myshop.com/return')
    ->setErrorUrl('https://myshop.com/return')
    ->setCancelUrl('https://myshop.com/cancel');

// Get the checkout page redirect URL
$checkoutPageService = CheckoutPageService::create($environment);
$redirectUrl = $checkoutPageService->getCheckoutPageUrl($checkoutPageItem);

Handling the checkout page response

After confirming the purchase on the checkout page, the user is redirected back to the shop. In order to complete the purchase, the payment must be committed via Easypay's REST API. Use the CheckoutPageResponseService to get the payment-ID or subscription-ID required to commit the payment:

use Gridonic\EasyPay\CheckoutPage\CheckoutPageResponse;

// Create an instance from the available GET parameters
$checkoutPageResponse = CheckoutPageResponse::createFromGet();

if ($checkoutPageResponse->isSuccess()) {
    $paymentId = $checkoutPageResponse->getPaymentId();
    
    // or if the submitted CheckoutPageItem is a subscription (recurrent service)
    $authSubscriptionId = $checkoutPageResponse->getAuthSubscriptionId();
} else {
    print_r($checkoutPageResponse->getErrorCode());
}

Commit payments

One-time (direct) payments need to be committed via Easypay's REST API. Use the RestApiService to do so:

use Gridonic\EasyPay\REST\RESTApiService;

$restApiService = RESTApiService::create($environment);

// Commit a direct payment
$directPaymentResponse = $restApiService->directPayment('paymentId');

if ($directPaymentResponse->isSuccess()) {
    // Payment commited successfully
} else {
    // A more detailed error is available as error message:
    $errorMessages = $directPaymentResponse->getErrorMessages();
    $errorMessage = array_pop($errorMessages);
    $errorMessage->getMessage();
    $errorMessage->getCode();
    $errorMessage->getField();
    $errorMessage->getRequestId();
}

In case of a service subscription, the procedure is similar:

// Authorize a subscription
$authSubscriptionResponse = $restApiService->authorizeSubscription('authSubscriptionId');

if ($authSubscriptionResponse->isSuccess()) {
    // Subscription authorized successfully
} else {
    $errorMessages = $authSubscriptionResponse->getErrorMessages();
    $errorMessage = array_pop($errorMessages);
    // ...accessing the error details is identical to the direct payment example above
}
