No webhook delivery exists on any surface. There is no subscribe endpoint, no signing secret, no retry policy, and no event schema — because there is no sender.
This page exists so the absence is discoverable. A docs site that simply omits webhooks leaves a reader assuming they exist and looking for the page.

​
What to do instead

Poll the signal feed

GET /api/signals is the only delivery mechanism for signals. Responses cache 300s, so polling faster than that returns cached bytes.

Push integrations

Slack, Discord, Teams, and Telegram receive outbound dispatches from the workspace API. That is push to a chat surface, not a webhook to your server.

​
Outbound integration dispatch

The workspace API can push to a connected chat surface:
Connect a destination first via POST /integrations/{slack,teams,discord}/connect, then test it with POST /integrations/{id}/test. See Slack and Discord. This is the closest thing to push delivery that exists, and it is deliberately one-way into a chat client — it will not call an arbitrary URL of yours.

​
Polling correctly

1

Poll no faster than the cache

300 seconds. Anything faster is wasted requests against stale-while-revalidate bytes.
2

Diff on signal_id, not on total

A feed whose count is unchanged may still have rotated its contents.
3

Check data_mode every time

A feed that flips to empty means the producing host stopped running, not that risk disappeared. Alert on that transition.
4

Treat generated_at as the freshness signal

A feed serving the same generated_at for hours is a stalled producer.
Step 3 is the one most integrations skip. An empty feed rendering as “all clear” is the data-state failure in its most expensive form.
