# Lucidworks Configurations API

**Canonical:** https://apis.io/apis/lucidworks/lucidworks-configurations-api/

**Base URL:** https://api.lucidworks.ai  
**Documentation:** https://doc.lucidworks.com/docs/5/fusion/dev-portal/rest-apis

Lucidworks Configurations API is one of 40 APIs that [Lucidworks](https://apis.io/providers/lucidworks/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Configurations. The published artifact set on APIs.io includes an OpenAPI specification.

The Configurations API allows setting global properties for Fusion. Some settings are not set by any configuration file but are reported as settings from the operating system. Those settings cannot be changed with this API. > ⚠️ **Blocked by default:** This API is blocked on the API gateway by default because it exposes all Fusion admin service environment variables. It can be enabled in special cases — contact [Lucidworks Support](https://lucidworks.com/support) to discuss your use case. In Fusion 5.18 and later, use [Fusion Vault](/docs/5/fusion/operations/security/external-vault) instead, which provides a safer, structured approach to managing configuration values and secrets. The Configurations API is deprecated as of Fusion 5.18.
