User Identification

B2Metric.setUser({
  userId: 'user_123',
  name: 'Ahmet',
  email: 'ahmet@example.com',
  plan: 'premium',
})

setUser sends a user_identify event and merges attributes into user_properties on every subsequent event. userId is required; any additional custom attribute is also accepted.

Note

Device-collected properties always win a key collision with a user attribute. User attributes are not persisted across restarts — call setUser again after each app launch.
