# Reattribute Experiment Endpoint

`POST /api/v1/gm/experiment/{experiment_id}/reattribute`

## Request

- Base URL: `https://app.goodleads.club` (the document declares no server; this is the origin it was published from)
- URL: `https://app.goodleads.club/api/v1/gm/experiment/{experiment_id}/reattribute`
- Auth: API key in header `X-API-Key`

Re-fetch a completed Tracerfy queue and re-attribute the cells — free.

Recovery for a run that billed spend but read the batch before the
vendor finished (the 2026-08-09 premature-poll incident): the results
still sit on the vendor's queue endpoint; this replays attribution from
each cell's stored submitted_attributes and updates output_artifact in
place. Idempotent. Admin-gated: it mutates experiment cells.

## Path parameters

- `experiment_id` string, required

## Request body

- ReattributeRequest
  - `queue_id` string, nullable

## Response `200`
