            var client = new GraphQLClient("xxx/api/graphql", null, headers, null);
            var request = new Request
            {
                Query = "query FindAccount($userId: Long!) { findAccount(userId: $userId) { " 
                        +"... on Account { id, type, userId, email, expirationDate, lastSubscriptionReminderDate, isDeveloper }"
                        +"... on NotFound { notFound }" 
                        +"... on BadRequestError { type, message }" 
                        +"... on AppError { type, message} } }",
                    Variables = new
                {
                    userId= this.userId().Value()
                }
            };
            var responseType = new { findAccount = new { type ="" , message =""} } ;
            var response = await client.Send( () => responseType, request);

How do I properly work on query that can return multiple response Types?

Thanks in advance Fer

Apologies for the super late reply.

There are several ways to handle this, but in your more complex use case, I recommend you receive the payload as a string using the non-generic method and then check your fields in the JSON response to figure out what to parse it to (similar to TypeScript).

The generic methods are there for convenience, but to support multiple types from the API, the easiest way is to parse the response string yourself.
