Mixpanel

Koryla sends experiment assignments to Mixpanel as Experiment Viewed events. You can then use Mixpanel's funnel and cohort tools to measure variant performance.

Setup

1. In Mixpanel, go to Project Settings → Access Keys and copy your Project token.
2. Enter the token in Dashboard → Integrations → Mixpanel and toggle it on.

What gets sent

{
  "event": "Experiment Viewed",
  "properties": {
    "distinct_id": "[session_id]",
    "token": "your-project-token",
    "experiment_id": "a1b2c3...",
    "experiment_name": "Homepage CTA Test",
    "variant_id": "x9y8z7...",
    "variant_name": "Blue button",
    "time": 1712793600
  }
}

The distinct_id is the Koryla session ID — an anonymous identifier persisted in the ky_session cookie.

Analyzing results in Mixpanel

Funnels

1. Go to Funnels → create a new funnel
2. Step 1: Experiment Viewed where experiment_name = "Your Test"
3. Step 2: your goal event (e.g. Signed Up, Purchase Completed)
4. Break down by variant_name

Cohort breakdown

Create cohorts based on variant_name and compare downstream behavior — retention, LTV, feature adoption, etc.

Notes

• Events fire once per visitor per experiment.
• The distinct_id is anonymous. If your site also identifies users in Mixpanel (e.g. via mixpanel.identify()), the anonymous and identified profiles won't be merged automatically. For full attribution use $distinct_id aliasing or the custom webhook integration with your own user ID.
