You can now create custom AWS Lambda authorizers that return API keys in their responses for APIs in Amazon API Gateway. This makes it easier to control usage plans assigned to API requests. You can use the application logic in your custom Lambda authorizer to determine the API key without needing the API client to specify it. This also allows you to map other request properties to an API key known to API Gateway. For example, you can map a different request header as the API Key.

To get started, create or update your API settings using the AWS Management Console, AWS CLI, or SDKs and APIs. Visit our documentation to learn more. 

This feature is now available in US East (N. Virginia), US East (Ohio), US West (Oregon), EU (Ireland), EU (Frankfurt), EU (London), Asia Pacific (Singapore), Asia Pacific (Tokyo), Asia Pacific (Sydney), Asia Pacific (Seoul), and Asia Pacific (Mumbai), AWS GovCloud (US) and China (Beijing) AWS regions.
