# Create Event

## Body Parameters

- `name` (string, required) — The name of the event. Used to match events to automation triggers.

  :::callout{intent="note"}
  The event name can be any string (e.g., `user.created`, `welcome`,
  `my-custom-event`). Dot notation is a recommended convention but is not
  required. If multiple enabled automations use the same event name, all of them
  will be triggered. Use unique event names if you want to target a specific
  automation.
  :::

  :::callout{intent="warning"}
  Event names cannot start with the `resend:` prefix, which is reserved for system events.
  :::

- `schema` (object) — An optional schema definition for the event payload. Must be an object with flat key/type pairs. Supported types: `string`, `number`, `boolean`, `date`.

    plan: 'string',
  },
});
