# Event Types

Event Streams organizes events by **Event Type**: a specific occurrence within a Twilio product, such as a message being delivered or a call completing. Each event type has one or more versioned [schemas](/docs/events/event-streams/schema-resource) describing its payload.

This page lists every available event type, grouped by product. Each link opens that event type's schema, versions, and example payloads.
