User guide

Transaction and order numbers

Shopware 5 generates an order number and a transaction number.

The order number is generated after the payment is completed (unlike most ecommerce integrations where it is generated at the beginning of the order).

The transaction number is generated when the transaction is initialized. MultiSafepay uses this number as the order ID in transactions.

Configuring generic gateways

The plugin supports generic gateways.

You can filter generic gateways by country, and minimum and maximum amount.

To configure a generic gateway:

  1. Sign in to your backend.
  2. Go to MultiSafepay settings.
  3. Set the relevant payment method gateway IDs.
  4. Upload a custom gateway image, if relevant.
  5. For pay later methods, specify whether to include a shopping cart.

Missing session data

It can happen that Shopware 5 will remove sessions before the order is created within the Shopware backend. To prevent this from happening we recommend making the following changes to the config.php.

'session' => [
    'save_handler' => 'db',
    'gc_probability' => 0,
    'gc_divisor' => 1000

This is also explained on the following page:

Processing refunds

You can process refunds for all Shopware 5 payment methods except pay later methods from your:

Refund rules

Shipping orders

For pay later payment methods, after you ship the order to the customer, you need to change the order status from Completed to Shipped. This prevents the order expiring, and lets the payment method initiate the billing process with the customer and pay the transaction out to your MultiSafepay balance.

If you change the order status to Delivered in your backend, the updated status is passed to your MultiSafepay dashboard automatically.

Updating the plugin

There are 3 ways to update the Shopware 5 plugin:

  • In your Shopware 6 backend
  • In the CMS marketplace

To update the plugin in your backend, follow these steps:

  1. Make sure you have a backup of your production environment, and that you test the plugin in a staging environment.
