# AWS::ApiGatewayV2::Integration ResponseParameter
<a name="aws-properties-apigatewayv2-integration-responseparameter"></a>

Supported only for HTTP APIs. You use response parameters to transform the HTTP response from a backend integration before returning the response to clients. Specify a key-value map from a selection key to response parameters. The selection key must be a valid HTTP status code within the range of 200-599. Response parameters are a key-value map. The key must match the pattern `<action>:<header>.<location>` or `overwrite.statuscode`. The action can be `append`, `overwrite` or `remove`. The value can be a static value, or map to response data, stage variables, or context variables that are evaluated at runtime. To learn more, see [Transforming API requests and responses](https://docs.aws.amazon.com/apigateway/latest/developerguide/http-api-parameter-mapping.html).
