# List session signals

`GET /v1/projects/{projectSlug}/sessions/{sessionId}/signals`

Returns the signals that occurred in the session, with occurrence stats scoped to the session's traces. Ordered by most recent occurrence first.

## Path parameters

- `projectSlug` string, required — Project slug (human-readable identifier)
- `sessionId` string, required — Session identifier lifted from instrumentation. Up to 128 characters.

## Response `200`

Signals of the session

- SessionSignals
  - `items` SessionSignal[], required — Signals that occurred in the session, ordered by most recent occurrence first.
    - `id` string, required — Stable signal identifier.
    - `organizationId` string, required — Organization that owns this signal.
    - `projectId` string, required — Project this signal belongs to.
    - `slug` string, required — URL-safe slug derived from `name`. Unique within the project.
    - `name` string, required — Human-readable name.
    - `description` string, required — Description of the signal.
    - `source` 'annotation' | 'flagger' | 'custom', required — Where the signal originated from.
    - `states` string[], required — Active lifecycle states. A signal may carry multiple states at once (e.g. `escalating` + `new`).
    - `resolvedAt` string, nullable, required — ISO-8601 timestamp at which the signal was resolved, or `null`.
    - `ignoredAt` string, nullable, required — ISO-8601 timestamp at which the signal was ignored, or `null`.

    - `mutedAt` string, nullable, required — ISO-8601 timestamp at which notifications were muted, or `null`. Muting only silences notifications; incidents still open.
    - `createdAt` string, required — ISO-8601 timestamp of creation.
    - `updatedAt` string, required — ISO-8601 timestamp of the last update.
    - `occurrences` integer, required — Number of occurrences within the session.
    - `firstSeenAt` string, required — ISO-8601 timestamp of the earliest occurrence in the session.
    - `lastSeenAt` string, required — ISO-8601 timestamp of the latest occurrence in the session.
    - `traceIds` string[], required — Traces of the session where the signal occurred.
