# POST /api/embed-theme/seed-defaults

`POST /api/embed-theme/seed-defaults`

Seed default embedding themes on first call, using the payloads built by the frontend from the
  `METABASE_LIGHT_THEME` / `METABASE_DARK_THEME` constants.

  Idempotent: guarded by the `default-embedding-themes-seeded` setting. Once flipped, subsequent calls
  are no-ops even if the admin has since deleted the seeded themes, so deletions are preserved.
