# Conference API Request

## Created

`com.twilio.voice.api-request.conference-participant.created`

> \[!NOTE]
>
> This event is only available when subscribed to in the original API request or TwiML response. In other words, your TwiML or API request must also provide a status callback URL and the events you wish to receive.

Conference API Request Created events are compatible with Webhook and Kinesis sinks. To learn more, you can get started with the [Webhook](/docs/events/webhook-quickstart) or [Kinesis](/docs/events/eventstreams-quickstart) quickstarts and refer to the [product documentation](/docs/voice/api).
