List of events

Event	Description
order.created	This event is sent by default to all the newly generated orders
order.deposit.processing	When the user has triggered a transaction (or clicked “I have Paid”)
order.deposit.success	Whenever an inbound transaction is received on the destination wallet. If multiple transactions are detected, events will be sent for each confirmed transaction.
order.deposit.failure	After the user has triggered the transaction, if no inbound transaction is detected within the shown ETA, this event is sent
order.smartcontract.processing	When virtual asset funds are being used to execute the smart contract
order.smartcontract.success	When the smart contract execution is successfully completed and confirmed on blockchain
order.smartcontract.failure	When the smart contract execution could not happen due to any reason, then it fails
order.success	This additional webhook event will be sent to represent the overall success of the journey
user.widget.open	Whenever the front-end screen is accessed by the user for the first time, this event is dispatched. In case multiple such events are received for a particular order, only the first one should be considered as the truth.
user.widget.close	Whenever user closes the front-end screen this event is sent. This event’s dispatch cannot be guaranteed and will be shared on a best-efforts basis. Due to certain technical constraints, it is difficult to detect closure of a front-end screen.
