[#next-free-field: 6] ``GrpcJsonReverseTranscoder`` is the filter configuration for the gRPC JSON reverse transcoder. The reverse transcoder acts as a bridge between a gRPC client and an HTTP/JSON server, converting the gRPC request into HTTP/JSON for the HTTP backend and the HTTP/JSON response back to gRPC for the gRPC client. This effectively reverses the behavior of the :ref:`grpc_json_transcoder filter <config_http_filters_grpc_json_transcoder>`, allowing a gRPC client to communicate with an HTTP/JSON server.

• string descriptor_path = 1

  Supplies the filename of :ref:`the proto descriptor set <config_grpc_json_reverse_transcoder_generate_proto_descriptor_set>` for the gRPC services. If set, takes precedence over the ``descriptor_binary`` field.

• bytes descriptor_binary = 2

  Supplies the binary content of :ref:`the proto descriptor set <config_grpc_json_reverse_transcoder_generate_proto_descriptor_set>` for the gRPC services. If ``descriptor_path`` is set, this field is not used.

• optional google.protobuf.UInt32Value max_request_body_size = 3

  The maximum size of a request body to be transcoded, in bytes. A body exceeding this size will provoke a ``gRPC status: ResourceExhausted`` response. Large values may cause envoy to use a lot of memory if there are many concurrent requests. If unset, the current stream buffer size is used.

• optional google.protobuf.UInt32Value max_response_body_size = 4

  The maximum size of a response body to be transcoded, in bytes. A body exceeding this size will provoke a ``gRPC status: Internal`` response. Large values may cause envoy to use a lot of memory if there are many concurrent requests. If unset, the current stream buffer size is used.

• string api_version_header = 5

  The name of the header field that has the API version of the request.
