# Update feature type lifetime

PUT https://app.unleash-instance.example.com/api/admin/feature-types/{id}/lifetime
Content-Type: application/json

Updates the lifetime configuration for the specified [feature flag type](https://docs.getunleash.io/concepts/feature-flags#feature-flag-types). The expected lifetime is an integer representing the number of days before Unleash marks a feature flag of that type as potentially stale. If set to `null` or `0`, then feature flags of that particular type will never be marked as potentially stale.

When a feature flag type's expected lifetime is changed, this will also cause any feature flags of this type to be reevaluated for potential staleness.
