## Overview{% #overview %}

Statsig's feature flag tracking integration enriches your Datadog RUM data with feature gate information, allowing you to measure causality between your product features and your system and performance metrics.

## Setup{% #setup %}

### Feature flag tracking setup{% #feature-flag-tracking-setup %}

Feature flag tracking is available in the RUM Browser SDK. For detailed set up instructions, visit [Getting started with feature flag data in RUM](https://docs.datadoghq.com/real_user_monitoring/guide/setup-feature-flag-data-collection.md).

1. Update your Browser RUM SDK version to 4.25.0 or above.
1. Initialize the RUM SDK and configure the `enableExperimentalFeatures` initialization parameter with `["feature_flags"]`.
1. Initialize Statsig's SDK (`>= v4.34.0`) and implement the `gateEvaluationCallback` option as shown below:

```js
await statsig.initialize('client-<STATSIG CLIENT KEY>',
  {userID: '<USER ID>'},
  {     
    gateEvaluationCallback: (key, value) => {
      datadogRum.addFeatureFlagEvaluation(key, value);
    }
  }
); 
```
