-## Webhooks (Optional)
-
-[Webhooks](../data-model/extras/#webhooks) allow NetBox to integrate with external services by pushing out a notification each time a relevant object is created, updated, or deleted. Enabling the webhooks feature requires [Redis](https://redis.io/), a lightweight in-memory database. You may opt to install a Redis sevice locally (see below) or connect to an external one.

-Enabling webhooks also requires installing the [`django-rq`](https://github.com/ui/django-rq) package. This allows NetBox to use the Redis database as a queue for outgoing webhooks.

 # Configuration
