###   Webhook API version


> **Note**
> Webhook API version can be configured in the dashboard -> Settings -> Webhooks Tab -> Webhook API version .





 After the completion of every payment/refund call, Juspay will provide direct notification to your server regarding the event. These are called Webhooks. You must configure a valid HTTP endpoint that is reachable from our servers to consume these notifications. Our servers will push data using HTTP POST call to your endpoint.Based on the API version configured in the dashboard, webhooks will be triggered for the events below:

* Payment Success
* Payment Failure
* Refund Success
* Refund failure
* Order Creation
* Transaction Creation
* Refund Moved to Manual Review.
