- Email Address
- Facebook ID
- Google ID
- Microsoft ID
- mParticle ID (MPID)

Prerequisites
In order to enable mParticle’s integration with LaunchDarkly, you will need to provide the specific user identifier you wish to use for exporting LaunchDarkly events.
Setup the Launch Darkly feed to get your key/secret. Enter these credentials into LaunchDarkly Data Export Destination form, selecting “mParticle” as the destination.
You also need to instrument your app with the LaunchDarkly SDK to send events.
Depending on your LaunchDarkly SDK implementation, when you create the mParticle destination in LaunchDarkly you may need to select different values for LaunchDarkly’s User Identifier and Anonymous User Identifier. Coordinate with your LaunchDarkly and mParticle account teams to confirm you are mapping user identities appropriately.
Reference LaunchDarkly’s documentation for more information on associating anonymous users with logged-in users.
