# How Webhooks Work

> How Rain webhooks work, how to set them up, and where to find the events available by category.

Webhooks let Rain notify your systems the moment something happens, so you can
react to card activity, transactions, transfers, disputes, and compliance changes
without polling the API. Rain delivers each event as a signed HTTP `POST` request
to the endpoint you configure.
