Merging Guest and User Sessions

A common pattern in onboarding is letting a user complete a Flow before they register an account. Without help, this requires a custom datastore, cookie or local-storage juggling, and hundreds of lines of code to map guest data to the real user.

Engage now lets you map all data and state from an unauthenticated user to their registered account with one line of code. Use `linkExistingGuestSessionToUser` in the Flows hook. Available in `@frigade/react` 1.38.8 and above.
