Revolut Webhooks (v1) (deprecated) API
:::warning This is the v1 of the Webhooks API. This version is deprecated. For the latest version of the API, see [Webhooks (v2)](https://developer.revolut.com/docs/api/business#tag-webhooks-v2). ::: A webhook (also called a web callback) allows your system to receive updates about your account to an HTTPS endpoint that you provide. When a supported event occurs, a notification is posted via HTTP `POST` method to the specified endpoint. If the receiver returns an HTTP error response, Revolut will retry the webhook event two more times. The following events are supported: - `TransactionCreated` - `TransactionStateChanged` You cannot choose which event type to subscribe to. When you create a webhook, you automatically subscribe to all supported events.
