What is a Single-Use Link?
A single-use link is consumed by its first successful redemption. An unused link can also expire.
Single-use does not mean identity-bound: if a valid link is forwarded before redemption, another holder may redeem it first. The established session has its own lifetime.
How LayerV Implements This
Set one_time_use when issuing a link through a supported API operation. Manage session duration separately, and revoke the link when its access must end before the normal limits.
