## Attach an Event to Your Trace

<CodeGroup>
  ```typescript JS/TS theme={null}
  await trace.event({
      id: "event-id",
      name: "travel-plan-emailed",
      tags: { "email": "JetSetJoe@travelo.com" },
  });
  ```

  ```python Python theme={null}
  await trace.event(
      id="event-id",
      name="travel-plan-emailed",
      tags={"email": "JetSetJoe@travelo.com"}
  )
  ```

  ```go Go theme={null}
  trace.AddEvent(
      "event-id",
      "travel-plan-emailed",
      map[string]string{"email": "JetSetJoe@travelo.com"}
  )
  ```

  ```java Java theme={null}
  Event event = trace.addEvent(
      "event-id",
      "travel-plan-emailed",
      Map.of("email", "JetSetJoe@travelo.com")
  );
  ```

<Note>
  Replace 'trace.event' with 'span.event' when you are creating events within a span
