The Authentication endpoint uses the user and session keys to generate a unique link that will automatically authenticate and direct a patient into their vision test experience.
For HIPAA compliance reasons, the links will expire within a few minutes after generation. These links should be generated and used on-demand to redirect patients into the vision test experience. Links should not be added to UI or to emails.
A link will not generate if a session has not been created.
Authentication links can be generated relative to your branded hostname, as long as a fully qualified domain name is provided. Both staging and production domains should be provided if used.
