Get a session event timeline

GET /v1/admin/runtime/sessions/{id}/events

• Operation ID: listRuntimeSessionEvents
• Tags: Runtime sessions
• Base URL: http://localhost:8787

Ordered runtime events for one session; page forward with after set to the previous nextAfter. If the runtime is unreachable the response is still 200 with { available: false }. Authenticates with a Platform staff JWT and permission, like every admin route; the backend calls the separate Runtime service on the caller's behalf (no Runtime API key is ever exposed or accepted).

Workflow: Integration guide.

Authentication: staff Bearer JWT with permission runtime.read.

Authentication

• Auth: staff Bearer JWT (Authorization: Bearer <access_token>) with the permissions below.
• Required permissions: runtime.read
