# About events

When configuring a webhook, you can use the UI to choose which events will send you payloads. Only subscribing to specific events limits the number of HTTP requests to your server. You can also subscribe to all current events and you can change the list of subscribed events anytime.

Each event corresponds to a certain action that can happen in your fleet. For example, if you subscribe to the `ride.created`event, you'll receive detailed payloads as JSON every time a ride is created in your fleet.

For a complete list of available webhook events and their payloads, see "[Event List](/webhooks/webhook-events/event-list.md)".
