# Listen and forward events

> Stream and forward webhook events from the WaaS 2.0 service using Cobo CLI.

<Tip>
  Try [Cobo WaaS Skill](/v2/guides/overview/cobo-waas-skill) in your AI coding assistant (Claude Code, Cursor, etc.). Describe your needs in natural language to auto-generate production-ready SDK code and debug faster 🚀
</Tip>

Use this command to establish a WebSocket connection to the WaaS 2.0 service and stream webhook events, as well as optionally forward them to a specified URL. You can use **Ctrl + C** to stop the event listening process.

<Note>This command is mainly intended for use in development and testing environments. For production environment, set up a proper webhook endpoint in your application as instructed in [Set up a callback or webhook endpoint](/v2/guides/webhooks-callbacks/set-up-endpoint).</Note>

## Usage

```shell theme={null}
cobo webhook listen [options]
```

## Options

* `--events <event_type>`: Filter the events by specifying event types. Replace `<event_type>` with the specific event types you're interested in and separate them by commas. Possible values for event types include:

  * `wallets.transaction.created`
  * `wallets.transaction.updated`
  * `wallets.transaction.failed`
  * `wallets.transaction.succeeded`
  * `wallets.mpc.tss_request.created`
  * `wallets.mpc.tss_request.updated`
  * `wallets.mpc.tss_request.failed`
  * `wallets.mpc.tss_request.succeeded`

  <Info>You can also run the [cobo webhook events](/v2/developer-tools/cobo-cli/event-types) command to get the latest list of all available event types.</Info>

* `--forward <url>`: Forward received events to the specified URL.
  <Note>When using this option, ensure that your endpoint is properly secured, especially if you're forwarding to a public URL.</Note>

## Example

```shell theme={null}
cobo webhook listen --events wallets.transaction.created,wallets.transaction.updated --forward "https://your-endpoint.com/webhook"
```

This command listens for the `wallets.transaction.created` and `wallets.transaction.updated` event types and forward the received events to the url `https://your-endpoint.com/webhook`.
