When a publisher user opts-in to push their content onto Nextdoor, the partner will make an initial API request to get or create the Nextdoor account, and receive a URL for the user to follow to establish an authenticated web session.
If a Nextdoor account does not exist for the specified email address, then one will be created. Nextdoor will return a login URL for the user to follow.
