Hi Ashna,
Good morning and thank you for writing in.
You can view features that have been marked stale by navigating to the main feature flag table in GrowthBook. There, you'll find a 'Stale' column which indicates whether a flag is considered stale. You can also navigate to a particular feature and see the stale indicator marked next to the feature name.
However, there is no explicit mention of an API endpoint that provides a list of all stale feature flags. We have a REST API
here, and we have launched an endpoint for listing all feature flags, but not one for determining which feature flag is stale.
In parallel to the above, I'm unsure if you are aware already but we have a public facing Feature Suggestion board available
here , where you may wish to submit this feature suggestion for other customers can upvote it.
If you have any more ideas or feedback in the future, please do not hesitate to reach out again. We are always eager to hear from you and continuously improve.
