# Feature Flag & Setting values V2

Copy page

*These endpoints are exclusive for [**Config V2**](https://configcat.com/docs/advanced/config-v2.md) Feature Flags.*<br />*They can only be used on a Config that has `evaluationVersion` set to `v2`.*<br /><br />With these endpoints you can control how your existing Feature Flags and Settings should serve their values. You can turn Feature Flags on or off, update Setting values and change Targeting Rules.

To determine which Feature Flag or Setting you want to work with you have to pass its `settingId`. It can be obtained from the [Feature Flag & Setting](https://configcat.com/docs/api/reference/feature-flags-settings.md) endpoints.

You also have to specify in which Environment you want to change the served value configuration by its `environmentId` which can be obtained from the [List Environments](https://configcat.com/docs/api/reference/get-environments.md) endpoint.
