PayPal Checkout configuration


PayPal Checkout requires the Pro version of the shop extension!


The PayPal Checkout requires the entry of the full URL in the site configuration of your TYPO3 instance!

PayPal Account

You will need a PayPal account. Log-in to PayPal and open https://developer.paypal.com. Go to My Apps & Credentials in the menu and create a new app. Take note of whether you want to create a Live or a Sandbox account. After creating it, you should have the following information

  • (Sandbox) Account: This is an email address.
  • Client ID: This is a hash value that identifies the client.
  • Secret: This is also a hash value. Make sure you keep it secret!

To set up the PayPal checkout, you only need the (sandbox) account. (See the sandbox and payPalId fields in the Checkout Configuration section).

For testing purposes you will need an extra account which you can set up under https://developer.paypal.com/developer/accounts/.


If your environment is password protected the webhook can't be executed. Please make sure that the webhook can be accessed.

Checkout configuration

  • active Activate/deactivate checkout
  • checkoutPid Enter the page Uid of the checkout page.
  • successPid Enter the page Uid of the success page. This is the page you will be redirected to after successful payment.
  • cancelPid Enter the page Uid of the cancel page. This is the page you will be redirected to if you cancel the payment process.
  • callbackPid Enter the page Uid of the callback page. The callback page is accessed asynchronously by Paypal to confirm payment.
  • service The checkout service PHP class is assigned here. This can be modified if the process needs to be changed.
  • sandbox Activate/deactivate the sandbox.
  • payPalId Enter the (sandbox) account name created in PayPal.

Add additional actions after a successful payment

If you need actions to be carried out after successful payment, use the PayPalPaid event listener.

  1. Create a new slot:
    namespace YourVendor\YourExtension\EventListener;
    use CodingMs\ShopPro\Event\BasketOrder\PayPalPaidEvent;
    class DoSomeThingEventListener
        public function __invoke(PayPalPaid $event): void
            /* Do something */
  2. Then register the event listener in Configuration/Services.yaml:
                - name: event.listener
                  identifier: 'myListener'
                  event: CodingMs\ShopPro\Event\BasketOrder\PayPalPaid

Additional actions after a successful payment

If you want to carry out further actions after successful payment use the payPalPaid signal/slot.

  1. Create a new slot:
    namespace YourVendor\YourExtension\Slot;
    use CodingMs\Shop\Domain\Model\BasketOrder;
    class DoSomeThingSlot
        public function doSomeThingFunction(BasketOrder $basketOrder)
            /* Do something */
  2. Then register the slot in ext_localconf.php:
    $signalSlotDispatcher = TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Extbase\SignalSlot\Dispatcher::class);


If a callback does not work, you can activate debugging. Read how this works in the How To/Debugging section.


PayPal callbacks are best tested by logging in to https://developer.paypal.com (using your real login data). Access the IPN Simulator under SANDBOX.

Enter your callback URL in the IPN handler URL then under Transaction type select Cart checkout. A large number of form fields will appear below the form. In the item_number field enter the Uid of your basket order so that the callback can find the right order.
