mParticle schema reference

This topic explains the different event kinds for mParticle Data Export destinations. The JSON schemas for mParticle are formatted differently than LaunchDarkly’s. The index, identify, and summary event kinds are not available in mParticle Data Export destinations, and other events are exported with different labels.

To learn more about the mParticle destination, read mParticle’s documentation.

There are four different event kinds mParticle uses. They are:

• Feature events: This event appears when a feature flag is evaluated.
• Click events: This event appears when an end user clicks on a CSS selector for which they have configured a metric in an experiment.
• Page view events: This event appears when an end user loads a page associated with an experiment metrics.
• Custom events: The LaunchDarkly SDK sends a custom event.
