Starting today, Amazon API Gateway supports multiple headers and query string parameters with the same name in the API Request.

Amazon API Gateway gives you the capability to quickly create, publish, maintain, monitor and secure APIs at scale. You can now pass multiple values for the same key in the header and query string when calling the API. This feature also supports returning multiple headers with the same name in the API response, for example sending multiple “Set-Cookie” headers.

This feature is available in all regions where API Gateway is available and China (Beijing) region operated by Sinnet, and Amazon Web Services China (Ningxia) region operated by NWCD. To see all regions where API Gateway is available, see the Amazon Web Services region table.
