Pass-Through API Authorization describes an authorization mechanism where requests to an API are authenticated and authorized tokens or permissions are passed through unchanged to downstream services. This enables secure propagation of access rights across layers in logistics and supply chain environments, without requiring the original client to re-authenticate. Typical technologies include token forwarding (e.g., OAuth 2.0) and JWT.
