Use LaunchDarkly to list, create, update, toggle, and delete feature flags, and inspect their environment-specific status. Toggling uses LaunchDarkly's semantic patch API.
Read projects, environments, segments, members, and audit logs to find targeting context or review changes. For example, toggle a flag after a deployment, then inspect its status and the resulting audit entry.
Authentication
Create a personal access token or service token under Organization settings > Authorization > Tokens in LaunchDarkly. Sim sends it directly in the Authorization header, without a Bearer prefix. Grant only the access the workflow needs. Service tokens are available on selected plans; SDK keys cannot authenticate REST API requests.
