Card Transaction Event
Webhook
Notifies your system whenever any transaction event occurs on a card, including:
- Transaction creation
- Transaction confirmation
- Transaction clearing
- Transaction status change
The payload structure is identical to the response of the Retrieve Card Transaction Details endpoint.
We send POST requests with card data to your configured endpoint.
A control signature is included in the headers as api-notification-sign (SHA512) to ensure security and authenticity.
See how to configure callback.
