About our API


Difference between direct and redirect API requests

In our API, you can make direct and redirect requests.

Direct requests

Direct requests connect directly to the specified payment method and either:

  • Generate a direct link to the payment method, e.g. specifying iDEAL in the gateway parameter takes the customer to the payment page of their bank.
  • Complete the transaction immediately without the customer having to do anything.

You can make …

Google Analytics tracking via our API

You can track the behavior of your customers through Google Analytics tracking.

This only applies to redirect requests. When the customer reaches the MultiSafepay payment page, the UA-code is generated and appears in the HTML.

Tracking isn’t available for direct requests because the customer doesn’t go to a MultiSafepay payment page between your checkout and success page.

Notification URL

Notifications are webhooks where the API notifies your web server when the status of a transaction changes. They are triggered by actions by:

  • Customers, e.g. completing a payment
  • Merchants, e.g. processing a refund

We add 2 parameters to the notification request:

  • transaction_id
  • timestamp

For POST requests, we add the order data to the request body.

You can ignore requests if:

Locale parameter

The locale parameter:

  • Localizes the payment page with the customer’s language, region, and available payment methods
  • Sends email templates in the customer’s preferred language
  • Specifies any special preferences for the user interface.

Note: If an email template is set for a German customer, but the locale parameter is en_US, the English email template is sent instead of the German …

Redirect URL

The redirect_url is the URL of your success/thank you page, where customers are directed after successfully completing payment, or if the transaction status is Uncleared.

Note: Customers never see an Uncleared status. They are still redirected to the success page. For more information, see Evaluating Uncleared transactions.

Unmasking IBAN numbers

International bank account numbers (IBANs) are sensitive data.

For security reasons, we mask IBANs by default in:

When masked, only the last 4 digits of the IBAN are visible, e.g. *** 1234.

Unmasking IBANs

You can still perform most business operations with masked IBANs, e.g. processing refunds.

To unmask IBANs for a specific website, …

Deprecated XML API

Our XML API was superceeded by the JSON API.

You can still use the XML endpoint to process transaction requests, but new payment methods, features, and tools are only supported by the JSON API.
