# Set Attribution

`POST /api/v1/profile/attribution`

## Request

- Base URL: `https://api.gemstoneaiapp.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.gemstoneaiapp.com/api/v1/profile/attribution`
- Auth: HTTP bearer

POST /api/v1/profile/attribution — persist first-touch install attribution.

Write-once: after attribution_captured_at is set the record is immutable,
so re-syncs from the app (or replays) can't overwrite first-touch.
