Integration
The `AWS::ApiGatewayV2::IntegrationResponse` resource updates an integration response for an WebSocket API. For more information, see Set up WebSocket API Integration Responses in API Gateway in the API Gateway Developer Guide.
Properties
Supported only for WebSocket APIs. Specifies how to handle response payload content type conversions. Supported values are `CONVERT_TO_BINARY` and `CONVERT_TO_TEXT`, with the following behaviors: `CONVERT_TO_BINARY`: Converts a response payload from a Base64-encoded string to the corresponding binary blob. `CONVERT_TO_TEXT`: Converts a response payload from a binary blob to a Base64-encoded string. If this property is not defined, the response payload will be passed through from the integration response to the route response or method response without modification.
A key-value map specifying response parameters that are passed to the method response from the backend. The key is a method response header parameter name and the mapped value is an integration response header value, a static value enclosed within a pair of single quotes, or a JSON expression from the integration response body. The mapping key must match the pattern of `method.response.header.{name}`, where name is a valid and unique header name. The mapped non-static value must match the pattern of `integration.response.header.{name}` or `integration.response.body.{JSON-expression}`, where `{name}` is a valid and unique response header name and `{JSON-expression}` is a valid JSON expression without the `$` prefix.
