Use customer identification after checkout to attach an email or external identity to an earlier quiz session.
Review Identified Profiles

- Capture the anonymous quiz session or user identifier.
- Send the known checkout email to the Identify API.
- Keep existing profile email values intact.
- Review the profile after processing.
- Confirm sync status in connected tools.
The Identify API is a no-op when the session and user pair has no quiz activity. Existing profile emails are not overwritten.
