# Webhooks: Not Available

> Data Hub does not have an outbound webhook system. This section documented one that doesn't exist and has been reduced to a stub.

<Warning>
  Webhooks are not in scope for the Data API's v1 roadmap. There is no `POST /webhooks` registration endpoint, no event system, and no signature verification to implement. This entire section previously described a fictional feature.
</Warning>

If you need to react to changes rather than fetch on a schedule, polling [`GET /variables/{dataHubId}/data`](/api-reference/query/run-query) with a recent `start` time is currently the only option.
