# TriggerClient: sendEvent() instance method

> The `sendEvent()` instance method send an event that triggers any Jobs that are listening for that event (based on the name).

You can call this function from anywhere in your backend to send an event. The other way to send an event is by using [io.sendEvent()](/sdk/io/sendevent) from inside a `run()` function.

Use [eventTrigger()](/sdk/eventtrigger) on a Job to listen for events.

For multiple events, use [client.sendEvents()](/sdk/triggerclient/instancemethods/sendevents) instead.

  ```ts Simple example with a payload
  const event = client.sendEvent({
    name: "new.user",
    payload: {
      userId: "u_1234567890",
    },
  });
  ```

  ```ts Send an event with an ID
  const event = client.sendEvent({
    id: "e_1234567890", // You can use this to deduplicate events
    name: "new.user",
    payload: {
      userId: "u_1234567890",
    },
  });
  ```

  ```ts Send an event to be delivered later
  const event = client.sendEvent(
    {
      id: "e_1234567890", // You can use this to deduplicate events
      name: "new.user",
      payload: {
        userId: "u_1234567890",
      },
    },
    {
      deliverAt: new Date("2023-12-01T00:00:00.000Z"),
    }
  );
