Terms and Conditions are sets of rules and guidelines that a user must agree to in order to place a booking. These are simply blocks of text that are shown to the traveler when they make a checkout. They may be shown as a link or as a modal window specifically prompting the user to accept the terms. Terms & Conditions configured for this experience override any terms that are configured at a global (user) level.
These set of end points allows you configure an account set of terms and conditions which will take effect if the experience does not have configured terms.
