Once candidates are invited and you've chosen to send an email invitation, they will receive an email allowing them to book on NexTravel.
This email invitation contains their temporary login link, "Book Now", so candidates aren't required to create a login on NexTravel. The login link will expire on the expiry date you set during the invite.
Click the "Book Now" button in the email, the candidates will be taken to NexTravel and they will first enter their traveler information.
After this, they will be taken to the home page where they can start searching and booking travel within the travel policy you've assigned to them.
If the candidate's travel policy requires approvals, you will follow the same approval process. Learn more about approvals here.
