# Events An event is the central entity of the platform. Everything that happens in your operation — a transaction, an authentication, a logistics milestone — reaches the platform in the form of an event. By modeling your occurrences as events, you gain a single, standardized entry point for data ingestion, regardless of the business domain. This allows you to: * **analyze data in real time**: track what is happening in your operation as events arrive; * **create custom metrics**: aggregate values, calculate rates, and track trends directly from received events; * **configure monitors**: define rules to detect anomalies, risks, or performance drops; * **evolve without coupling**: add new fields and event types without breaking existing integrations.

## How events are organized Each event belongs to an **event type**, which defines the expected data contract — which fields exist, their types, and whether they are required. These types can represent different business contexts, such as financial transactions (`transaction`), user authentication (`user_authentication`), and logistics delivery milestones (`logistics_delivery_event`). You define event types according to the reality of your operation and send occurrences to the `POST /events` endpoint. The platform validates, processes, and makes the data available for analysis, metrics, and monitors. ## Table of contents - [Event types](/en/events/event_types/index.html.md) - [Fields](/en/events/event_fields/index.html.md) - [Events](/en/events/events/index.html.md)
