Create a new webhook for the authenticated user's company.

The webhook will receive HTTP POST requests with event data when subscribed events occur.

A unique secret key is automatically generated for signature verification. The secret key is only returned in the response when creating or regenerating the webhook secret, so make sure to store it securely. If you lose the secret key, you can regenerate it using the "Regenerate Webhook Secret" endpoint, but this will invalidate the old secret immediately.

The maximum number of webhooks allowed per company is 50. If you have reached this limit, you will need to delete existing webhooks before creating new ones.

One webhook can be subscribed to multiple events, but each event can only be subscribed to once per webhook. For example, you cannot subscribe to the "review.created" event twice on the same webhook, but you can subscribe to both "review.created" and "review.updated" on the same webhook.
