Documented steps Create a Render API key at https://dashboard.render.com/ (Account Settings > API Keys) Open a WebSocket connection to wss://api.render.com/v1/logs/subscribe with header Authorization: Bearer <api_key> set on the upgrade request Include the required query param ownerId={workspace_or_owner_id} Filter with optional repeated query params resource=<resource_id> (multiple allowed) plus level, type, text, statusCode, method, path filters Optionally bound the stream with startTime / endTime (ISO 8601) After the HTTP 101 upgrade, consume JSON log objects from the socket (id, message, timestamp, labels) Reconnect with backoff when the socket drops; filters are fixed at subscription time Docs: https://api-docs.render.com/reference/subscribe-logs (historic queries: GET /v1/logs)
Known gotchas ownerId is mandatory — omitting it returns 400; it is the workspace/owner ID, not a service ID The Authorization header must be sent on the WebSocket upgrade request itself; some WS clients need explicit header support All requested resources must belong to the same owner and region; mixed queries are rejected Changing filters requires closing and reopening the socket — filters cannot be updated mid-stream There is no batching/backpressure control; the client must keep up or buffer For historic (non-live) logs use GET /v1/logs with the same filter vocabulary instead of the WebSocket
