Our service allows for expiring transactions, so library implementations are possible. You can set a downloaded eBook to expire within a given period of time so that it is unusable after that period and is automatically 'returned'. You could also set a limit to how many copies of an eBook can be accessed at any given time.
There are two ways to set an expiration date on eBooks.
- The transaction endpoint of our API deals with the expiry of the eBook itself after it's been downloaded by a user. So you have the eBooks become inaccessible by the user after a certain period of time.
- You can also set expiration through the Books page on your account dashboard when adding or editing an eBook, using the "Default DRM Settings" section on your dashboard.
