Transaction Event

METHOD NAME transactionEvent

Description

The transactionEvent notification is a callback triggered during transaction processing when the notifyEvents flag in the request is set to true. This notification provides real-time updates about the transaction's progress, allowing the client to track important steps in the payment flow.

How It Works

• The client must enable event notifications by setting notifyEvents: true in the transaction request.
• Once enabled, the device will send transactionEvent notifications at specific transaction stages.
• These events are sent as JSON-RPC notifications (without an ID and no response required).
• The client application should listen for these notifications and react accordingly.

Parameters

object

• type TransactionEventType
  The current state of the transaction
