# Reset a system setting to ENV / built-in default

`DELETE /system/admin/settings/{key}`

Removes the DB override for :key so the 3-tier resolver
falls back to the environment variable (when configured)
or the in-code default. Idempotent — resetting a key
that was never persisted returns 200.

## Path parameters

- `key` string, required

## Response `200`

Reset acknowledged

## Other responses

- `400` — Unknown key
- `500` — DB write failed

## Changes

  - endpoint added
- **2025-12-16** `edf61e68559d` — 1 breaking
  - api path removed without deprecation
