Profiles

We turn visitors into profiles when you send custom user data via setUser() method.

Profiles are a way to keep track of your authenticated users — those with a persistent ID in your application, such as userId or email — and are an excellent tool for analyzing user behavior when combined with user journeys. Send in any user properties, so you can later explore them by clicking on a specific visitor on the visitors page.

Some of the features that use profiles:

• Churn and engagement filters
• Stripe integration
• AI-powered insights

With both profiles and custom events, you are all set for a simple yet powerful product analytics.

How to identify a user

We merge users by either userId or email. If we receive a field that is already set, it gets overwritten.

Use the setUser() method to identify a visitor and set custom properties to their profile (available in both client and server libraries).

// could be done from client or server
seline.setUser({
  userId: "unique-user-id", // unique userId OR email is required
  name: "John Wayne", // name will be displayed at the visitor list and profile
  email: "[email protected]",
  plan: "enterprise",
  credits: 140,
  projects: ["Project A", "Project B"],
  // ... and any other custom properties; values can be in any format, but will be stringified.
});

We recommend identifying the user every time their session starts, so all their page views and custom events are tracked properly.
