You want to use the well-known types “Struct” or “Value”, which are
specifically designed to support ad hoc JSON parsing. “Struct” supports
parsing any valid JSON object structure, “Value” can parse any valid JSON:
message User {
string email = 1;
string firstName = 2;
string lastName = 3;
google.protobuf.Struct metadata = 4;
}
