The Identify API Method is used to attach data to a visitor and manage contact creation or updates.
  • Tags and custom fields that do not exist are created automatically.
  • Existing tags and custom fields are updated with the new data.
  • Properties are additive: no data is removed based on subsequent Identify calls.
