Integrate OneSignal with Mixpanel to send detailed message engagement events and import behavioral user cohorts. This enables real-time targeting based on user behavior to improve onboarding, re-engagement, and conversion.

​

Key benefits

• Send message events to Mixpanel: Track delivery, clicks, failures, and more across push, in-app, email, and SMS.
  • Real-time insights – Unify Mixpanel product analytics with OneSignal engagement metrics.
  • Data-driven campaigns – Run smarter re-engagement using Mixpanel’s behavioral segmentation.
• Import cohorts from Mixpanel: Automatically sync behavior-based cohorts into OneSignal as filters for targeting.
  • Personalized messaging – Trigger contextual OneSignal messages when users enter or exit Mixpanel cohorts.

Setup

​

Add Mixpanel to OneSignal

In OneSignal, navigate to Data > Integrations > Mixpanel and click Activate.

In Mixpanel:

1. Find your Project Token then copy-paste it into OneSignal.
2. Check your Data Residency. If using Mixpanel’s EU servers, check the Send events exclusively to Mixpanel’s EU Residency Server box.

​

Select message events

Select which OneSignal message events you want to send to Mixpanel. When finished, click Activate.

​

Add OneSignal to Mixpanel

In your Mixpanel Integrations, add OneSignal.

Set the Connector Name as something identifiable like OneSignal - APP_NAME where APP_NAME is the name of the app in OneSignal.

You will need the following data available in OneSignal Settings > Keys & IDs :

1. App ID
2. API Key

​

USER ID mapping

To match users across both systems:

• Use a shared identifier: The External ID in OneSignal must match an Mixpanel User ID Property selected (like user_id).
• Verify that the selected user property exists across your Mixpanel and OneSignal User Profiles.

Verify the User ID Property you selected is available in your Mixpanel user profile properties.

The same value in Mixpanel for the user profile property must match the External ID in OneSignal.

Click Continue when finished.

​

Export Mixpanel cohorts to OneSignal

You can sync the users within your Mixpanel cohorts to the users within OneSignal as long as they have the matching User ID/External ID property discussed in the previous step.

Exporting user data from Mixpanel does not create the user in OneSignal, the user must already exist and have the matching External ID.

To export users from Mixpanel to OneSignal:

1. In Mixpanel, create a cohort.
2. Click Options > Export to… > The OneSignal Connection name.

3. Choose sync frequency and press Begin Sync.

​

OneSignal Segment creation

• The synced cohort appears in OneSignal as an Mixpanel Segment filter.
• A Segment for the cohort will automatically be created if the following conditions are met:
  • The users in the Mixpanel Cohort also exist in OneSignal with matching External ID.
  • You must not exceed your Segment limit in OneSignal.

If both conditions are met, OneSignal will automatically generate a Segment using the Mixpanel Cohort filter and name of the Cohort.

Track message events in Mixpanel

Once connected, OneSignal will send message events to Mixpanel in real time.

To test this, send yourself a message from OneSignal, then navigate to your user profile page in Mixpanel.

Within the Activity Feed, you should see the events populate:

FAQ

​

Why don’t my cohort & segment counts match?

1. Missing or mismatched External IDs Only users with a matching OneSignal External ID and Mixpanel User ID are included. This integration doesn’t create users or subscriptions.

2. Unsubscribed users OneSignal segments only display the count for subscribed Subscriptions. Unsubscribed Subscriptions are available for Journeys or In-App Messages.

For example, if an Mixpanel cohort has 10 users but the OneSignal segment shows 8 Subscriptions, the 2 missing users may:

• Not exist in OneSignal or have an incorrect External ID.
• Have unsubscribed subscriptions.

To verify, check the Audience > Users tab in OneSignal to see if the users exist and have active subscriptions.

​

Do unsubscribed users sync from Mixpanel?

Yes, but they are excluded from the OneSignal segment counts at this time. You can still message them via Journeys or In-app messsages if they have other Subscriptions or their Subscription type supports it.

​

Why doesn’t delivery data match?

A single user may have multiple Subscriptions (push devices, email addresses, phone numbers). Each Subscription generates its own delivery event. For example:

• 1 user = 2 Android + 1 iOS + 2 Web = 5 push Subscriptions
• 1 push message = up to 5 sent/received/clicked events

Use the subscription_id in event properties to trace the exact source.

To troubleshoot missing events:

• Ensure OneSignal.login is called whenever a user is identified to set the External ID.
• Verify that OneSignal.logout isn’t removing the External ID.
• Check API requests or CSV uploads that may alter the External ID.

​

How can we send user/subscription events?

User and subscription-level events (e.g., permission granted, user login/logout) are not automatically sent.

The OneSignal SDK has event listeners that can be used to track these events for you to send to Mixpanel:

• User State Observer: Mobile SDK , Web SDK
• Permission Observer: Mobile SDK , Web SDK
