Webhooks
The Cardknox gateway can be set up (on the backend by Cardknox support) to send webhooks to a specific URL to notify your system of every transaction that is processed on a specific Cardknox account. It will be sent as a POST key-value pair URL encoded and will contain all information needed to identify the transaction, including the transaction status. The fields that are returned can be adjusted according to your needs. For a full list of available fields, see Response parameters.
