Reference
Exhaustive listings — REST API, webhook payloads, limits, and configuration tables.
What's in this section
Reference pages are the source of truth for shapes, names, and exhaustive lists. They are intentionally dry — if you want narrative, see Concepts or Tutorials.
- REST API — every endpoint, request/response shape, error code.
- Webhooks — outbound payloads, headers, signature verification.
- Limits & quotas — per-tier numerical limits (monitors, heartbeats, status pages).
Reference content rarely changes. When it does, the page header carries a "Last updated" stamp so you can confirm freshness at a glance.
