# Webhook

<Tip>
  **TIP**

  For complete information about webhooks in general and how to integrate them into your product or workflow, please see the [complete webhook reference](/resources/webhooks/).
</Tip>

Rewards webhooks notify you when any new data is available after a successful rewards fetch.

These webhooks fire only after a completed rewards fetch. Actions performed on the `member` through other endpoints will not trigger the webhook.
