Send event data to LaunchDarkly

The configuration process for this destination mirrors Segment's setup. We've automatically modified the documentation from third-party sources to show you how to set up this destination with PostHog.

LaunchDarkly is a feature management platform that empowers development teams to safely deliver, control, and measure their software through feature flags.

With LaunchDarkly, you can run experiments on any feature flag. This destination allows you to connect existing PostHog events to LaunchDarkly custom metrics for use in LaunchDarkly experiments.

Good to know: This page is about the Actions-framework LaunchDarkly PostHog destination. There's also a page about the non-Actions LaunchDarkly destination. Both of these destinations receives data from PostHog.

Installation

To get started with LaunchDarkly:

1. In LaunchDarkly, navigate to Account settings and copy the client-side ID for the project and environment that you would like to connect to PostHog.
2. From the PostHog web app, click Data pipelines, then click Destinations.
3. Search for LaunchDarkly and select it.
4. Click Configure LaunchDarkly.
5. Select the Source you want to connect to LaunchDarkly.
6. Paste the LaunchDarkly client-side ID you copied in step 1 into the LaunchDarkly client-side ID field on the destination settings page.

info "A note about Identify calls" LaunchDarkly doesn't store user attributes for use with flag evaluations. As a result, PostHog doesn't support mapping Identify calls to LaunchDarkly actions.
