# UpdateFeatureGroup
<a name="API_UpdateFeatureGroup"></a>

Updates the feature group by either adding features or updating the online store configuration. Use one of the following request parameters at a time while using the `UpdateFeatureGroup` API.

You can add features for your feature group using the `FeatureAdditions` request parameter. Features cannot be removed from a feature group.

You can update the online store configuration by using the `OnlineStoreConfig` request parameter. If a `TtlDuration` is specified, the default `TtlDuration` applies for all records added to the feature group *after the feature group is updated*. If a record level `TtlDuration` exists from using the `PutRecord` API, the record level `TtlDuration` applies to that record instead of the default `TtlDuration`. To remove the default `TtlDuration` from an existing feature group, use the `UpdateFeatureGroup` API and set the `TtlDuration` `Unit` and `Value` to `null`.
