# Get Signal

`GET /api/v1/public/signals/{signal_id}`

## Request

- Base URL: `https://app.traceroot.ai`
- URL: `https://app.traceroot.ai/api/v1/public/signals/{signal_id}`
- Auth: HTTP bearer

Get one signal of the caller's project. A merged signal names the signal it moved to.

## Path parameters

- `signal_id` string, required

## Query parameters

- `project_id` string, nullable: Target project for the request. Required when authenticating with a user session token (a user credential is only meaningful scoped to a project); for an API key it is optional and, if given, must match the key's project.

## Response `200`

Successful Response

- SignalDetail: One signal, including when it was resolved and whether it was merged. A merged signal is still answered, with ``merged_into_id`` naming the signal its findings moved to; lists leave merged signals out.
  - `created_at` string, date-time, required
  - `detector_id` string, required
