**Configuration**: Set `web.api.gsa=true` in `system.properties` to enable GSA compatibility features.

For most migration scenarios, we recommend using the modern JSON Search API (`/api/v1/documents`) instead.

### Admin APIs

All admin APIs require authentication (`-u admin:admin` or Bearer token).

**Base Path**: `/api/admin/`

**Available Endpoints**:
- `POST /backup/upload` - Upload backup/import files
