Incremental authorization is a payment feature that allows a merchant to request additional funds on a previously authorized transaction without requiring the customer to re-enter their payment credentials.
Enable Incremental AuthorizationIncremental Authorization requires additional configuration on the Nayax side. If you wish to support it, please contact your assigned Nayax integration engineer.

​
How to implement

After a successful Authorization, if the merchant asks for Incremental, your endpoint will receive one or more Cortina Credit Card Incremental Auth request, the BasicInfo.Amount in this request will be the incremental amount. The PaymentInfo object will include the details for the linked authorization. The Response for this request is similar to a regular Authorization response. The final settlement amount will be sent in the Cortina Credit Card Settlement request in the BasicInfo.Amount field.
