As its input, the function accepts the HTTP request data and values of the parameters listed in the specification. As the output, it returns the result of function execution to the client. The request data is transmitted in the same format as that of the current version of HTTP-integration when invoking the function with the integration=raw request string parameter that is most compatible with the AWS API Gateway format. The values of parameters listed in the specification are passed to the params field of the data parameter.
