To setup a webhook site webhook you first need to curl a GET request to `https://set-webhook.val.run?token=$WEBHOOK_API_KEY` so that the webhook can actually send the information to your machine.

After that you can invoke the script in `./scripts/webhook.js` to setup the listeners that will send you new messages whenever the webhook has something.

```bash
node ./scripts/webhook.js
```
