contentHandlingStrategy

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.
