wireFormat property

String? wireFormat
getter/setter pair

The format of communication supported by the callout extension.

If not specified, the default value EXT_PROC_GRPC is used.

Optional. Possible string values are:

  • "WIRE_FORMAT_UNSPECIFIED" : Not specified.
  • "EXT_PROC_GRPC" : The extension service uses ExtProc GRPC API over a gRPC stream. This is the default value if the wire format is not specified. The backend service for the extension must use HTTP2 or H2C as the protocol. All supported_events for a client request are sent as part of the same gRPC stream.

Implementation
