### Generic API
You can use the generic API to manually track feature flag evaluations. These evaluations are held in memory and are sent to Sentry on error and transaction events. **At the moment, we only support boolean flag evaluations.**

We might want to call out how many feature flags you can set.


```php
\Sentry\addFeatureFlag('test-flag', false);

\Sentry\captureException(new \RuntimeException("Something went wrong!"));
```

Go to your Sentry project and confirm that your error event has recorded the feature flag "test-flag" and its value "false".
