It is now possible for guests to modify their reservations online, including the ability to remove dates and/or rooms from their bookings. To set this up, you'll need to create two email templates: one for cancellations and one for modifications. Additionally, three website messages are needed: a page header message, a confirmation message after a cancellation, and a confirmation message after a modification. Once these elements are configured, you can finalize the setup by navigating to the Reservation Pages settings under the Website tab. Finally, make sure to include the modification merge code {{cancellationlink}} in your correspondence, such as in the initial confirmation email, and you can also find this link on the Reservation Details page under the More button.
