[`WebhookPayload`] is the main data structure that contains the payload from Webhooks. This is
a `pydantic` class which makes it very easy to use with FastAPI. If you pass it as a parameter to a webhook endpoint, it
will be automatically validated and parsed as a Python object.  
For more information about webhooks payload, you can refer to the Webhooks Payload [guide](https://huggingface.co/docs/hub/webhooks#webhook-payloads).
