What is a processing account?

A processing account defines how transactions are handled based on business rules, terminal setup, and currency. It controls settings such as:

  • Authorisation type (final or pre-authorisation)

  • Use of 3D Secure for customer-present transactions

  • Allowed payment methods

  • Any capture delay configurations

Processing accounts are labeled (e.g., EUR3D1, USD3D1) and can be found in the Merchant Portal.

To view your processing accounts:

  1. Go to the Merchant Portal sign-in page

  2. In the left-hand menu, click Processing Accounts

What is a payment reference?

A payment reference is a unique payment ID generated by the Gateway system. It is used to identify transactions and is only visible within the Gateway environment.

Is STAN unique?

The STAN (System Trace Audit Number) is a 6-digit identifier that is unique only for 24 hours after the transaction.


To ensure full uniqueness, combine the STAN with the transaction date (timestamp).

Does the order reference need to be unique?

Yes — by default, the order_reference parameter must be unique. It links the payment in the system to the correct order in the merchant’s e-shop.

Enforcing uniqueness has two main benefits:

  • Ensures accurate matching between orders and payments

  • Adds an extra security layer against tampering attempts

However, if needed, this uniqueness check can be disabled. When disabled, multiple payment attempts can be made using the same order_reference until a payment is successfully completed.

Where can I find integration settings and test cards?

Log in to the Merchant Portal and go to Settings > General Settings.
There, you’ll find the integration settings and available test cards for sandbox testing.
