- Services: API Gateway
- Release Date: Sept. 14, 2022
You can now use multi-argument authorizer functions for authentication and authorization. A multi-argument authorizer function accepts a user-defined, multi-argument access token comprising one or more elements of a request.
Using a multi-argument (rather than a single-argument) authorizer function enables an API gateway to perform finer-grained, request-based authentication. A multi-argument authorizer function can query decision services and policy agents with attributes from the access token and with other request elements such as query parameters, hostname, and subdomain.
