Order Reference Parameter
The primary purpose of the order_reference parameter is to link a payment in the gateway system to the corresponding order in the merchant’s e-shop.
By default, the order_reference value must be unique. Enforcing uniqueness helps ensure that each payment is associated with a single order and provides an additional layer of security by protecting against tampering or duplicate payment attempts.
Disabling Uniqueness Validation
If necessary, the uniqueness validation for order_reference can be disabled. When this validation is turned off:
Multiple payment attempts are allowed for the same order reference
Payments can be retried until a successful transaction is completed
This option is typically used in scenarios where merchants want to support repeated payment attempts for a single order without generating a new order reference.
