Identify user
MarkTag automatically assigns a unique ID to every user. You can add more information to further classify the user.
javascript
MarkTag.setUser({
email: "user@email.com",
phone: "xxxxxxxxxxx",
});Note that if you call MarkTag.logLogin() or MarkTag.logSignup() upon authentication, you can skip this step. But you can still use this when you expect the user to be already logged in to your app.
