How to manage dark features in Jira
Platform notice: Server and Data Center only. This article only applies to Atlassian products on the server and data center platforms.
Problem
Some of the features in Jira are not enabled by default and it is implemented as a dark feature (also known as feature flags).
Be careful with dark features as they may cause problems if misused since they will impact the entire instance. They should only be used when instructed by Atlassian Support.
As best practices, validate on a lower environment first before applying to production and a full backup is advised before making changes to dark features for the first time.
Solution
To manage dark features, access the following URL as a Jira administrator account:
<BASE_URL>/secure/admin/SiteDarkFeatures!default.jspa
Enabling a Dark Feature
In order to enable a feature flag, type <feature_flag_name>.enabled in the Enable dark feature text area and click the Add button.
Make sure to not have double ".enabled" suffix at the end of feature flag name.
Disabling a Dark Feature
To disable a feature flag:
- Click disable link next to the specific feature flag in the left section (as on a screenshot below)
OR
- Type <feature_flag_name>.disabled feature flag in the Enable dark feature text area and click the Add button.
- Make sure to not have the combination of suffixes ".enabled.disabled" at the end of the feature flag name.
If the Dark Feature is not present on the admin page it means it has its default value which may be enabled or disabled depending on the specific Dark Feature.

Managing dark features using the REST API
It is possible to manage dark features in Jira using the following private endpoint: /rest/internal/1.0/darkFeatures/{key}
This is a private API that is used by Atlassian within the product. This API can change without notice.
Instructions
Perform a PUT method on the endpoint above with the following JSON body (true or false depending if you want to add or remove the feature flag):
{ "enabled": "true" }Where {key} is the dark feature key. Example:
<BASE_URL>/rest/internal/1.0/darkFeatures/sd.sla.improved.rendering.enabledcURL syntax example:
curl -u user:password -X PUT <BASE_URL>/rest/internal/1.0/darkFeatures/{key} -H 'Content-Type: application/json' -d '{ "enabled": "true" }'Configuration Persistency
Jira stores the current configured dark features in the database table feature.Dark Features will persist service restarts and node replacements on a Jira Data Center environment.
