# Update a configuration

> **API operation:** [Open the endpoint in Scalar](https://docs.ordering.co/api-reference/#tag/configs/PUT/configs/{config})

Use `PUT /configs/{config}` to update one configuration by its numeric identifier. The current public operation is `Config.update`.

The final path parameter is `{config}` and identifies the configuration. Older integrations may refer to this identifier as `config_id`.

The route is restricted to server or administrator access. Send only fields that need to change. `key`, `value`, `type`, `options`, and `image` follow type-specific validation; image-backed type `5` can store the processed image result as `value`.

Protected or confidential configuration behavior is enforced by the controller. Do not include real provider credentials or protected values in request examples, logs, documentation, or client-side code.

## Legacy SDK example

```javascript
const response = await ordering.configs(configId).save(changes)
```

This SDK helper is legacy syntax; confirm that your package and version support it before use.
