LaunchDarkly (Edge)

Last updated on Nov 13, 2026

LaunchDarkly is a feature management platform that teams use to release features with feature flags, target them to specific users and segments, and run experiments.

Hevo uses the LaunchDarkly REST API to replicate the projects, environments, feature flags, segments, metrics, teams, and audit log of your LaunchDarkly account to the Destination of your choice. To ingest data, you must provide Hevo with an API access token of your LaunchDarkly account.

Handling of Deletes

LaunchDarkly does not mark deleted records in its API responses. Hevo handles deletes as follows:

  • Environment, Feature Flag, Flag Default Project, Metric, Project, Segment, and Team objects: Hevo ingests all the records of these objects in each run. If a record that exists in the Destination is not returned by LaunchDarkly, Hevo marks it as deleted by setting the value of the metadata column, __hevo__marked_deleted, to True. LaunchDarkly does not return archived feature flags, so Hevo marks an archived feature flag as deleted.

  • Child objects of Audit Log: Each time Hevo ingests an audit log entry, it replaces the child records of that entry in the Destination.

  • All the other objects: In each run, Hevo ingests all the records of these objects and replaces the Destination table with them. A record that is deleted in LaunchDarkly is removed from the Destination. For example, if you delete a feature flag, Hevo removes its variations from the Destination, instead of marking them as deleted.

  • Audit Log object: Hevo does not capture deletes for this object. Audit log entries that LaunchDarkly removes after its retention period remain in the Destination.


Source Considerations

  • Hevo ingests the audit log entries that LaunchDarkly retains for your account. The retention period depends on your LaunchDarkly plan. Entries that LaunchDarkly removed before the first run of the Pipeline are not ingested.

  • If your LaunchDarkly plan does not include teams, or your access token cannot read teams, Hevo marks the Maintainer, Role, Role Project, Team, Team Access, and Team Project objects as inaccessible and ingests the other objects.

  • Hevo creates a table in the Destination only for the objects that have data. For example, if your account does not use experiments, the Feature Flag Experiment table is not created.
