Enabling Session Replay with Internal ID for Cross-Device Tracking

·Oct 02, 2025 12:50 PM·

Hi, we just enabled Session Replay for our application. We doesn't care about build in distinctId as our flow can we spread across multiple devices and all our metrics care about our internalId which is added to every event. It is possible to make that works similar for session replay as for metrics?

Hi Sewo- Julianne from Mixpanel Support here! Session replays are linked together based on the $distinct_id associated with them, along with the $mp_replay_id. This means that the users across multiple devices would need to have the same $distinct_id along with the same $mp_replay_id. It sounds like users in your application have different distinctId's even if they have the same internalId. Given this, it wouldn't be possible to have the session replay work across those users.
