# Record Attribution

`POST /api/auth/attribution`

Record where a brand-new account came from. First touch wins.

Fire-and-forget from the client right after sign-in: it never fails the
sign-up, it just returns ``recorded: false`` when the row already exists or
the account is too old to be a genuine sign-up.

  - `referrer` string, nullable
  - `landing_path` string, nullable

  - `utm_medium` string, nullable
