wireFormat property

String? wireFormat
getter/setter pair

The format of communication supported by the callout extension.

This field is supported only for regional AuthzExtension resources. If not specified, the default value EXT_PROC_GRPC is used. Global AuthzExtension resources use the EXT_PROC_GRPC wire format.

Optional. Possible string values are:

  • "WIRE_FORMAT_UNSPECIFIED" : Not specified.
  • "EXT_PROC_GRPC" : The extension service uses ext_proc 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.
  • "EXT_AUTHZ_GRPC" : The extension service uses Envoy's ext_authz gRPC API. The backend service for the extension must use HTTP2 or H2C as the protocol. EXT_AUTHZ_GRPC is only supported for regional AuthzExtension resources.
