Cannot create conference participant with custom parameters

Question

I am having trouble creating a Conference Participant using the ReST API in twilio. The following is my request:

participant = ParticipantResource.Create(
                    new CreateParticipantOptions(
                        "conferenceName",
                        new PhoneNumber("client:791ecf-263c-49eb-9b9b-b6a265ee28d8"),
                        new PhoneNumber("client:59191ecf-263c-49eb-9b9b-b6a265ee28d8?agentFirstName=Michael&agentLastName=Scott++"))
                    {
                        Beep = Conference.BeepEnum.True.ToString(),
                        EndConferenceOnExit = true,
                        ConferenceStatusCallback = new Uri(statusCallbackUrl),
                        ConferenceStatusCallbackMethod = HttpMethod.Post,
                        ConferenceStatusCallbackEvent = new List<string>()
                        {
                            Conference.EventEnum.Start.ToString(),
                            Conference.EventEnum.Join.ToString(),
                            Conference.EventEnum.Leave.ToString(),
                            Conference.EventEnum.End.ToString()
                        }
                    }
                );

I believe this is the correct way to invoke this method to create a participant. I want to dial from agent 1 to agent 2, in order to get agent 2 into the conference call.

The conference call, create participant reference that I have followed is: https://www.twilio.com/docs/voice/api/conference-participant-resource

I want to pass the custom parameters to agent 2 who is logged in from the web client, in order to show agent 2 who is calling him.

You posted an answer the same time you posted the question, why, I am confused :) — Trevor

The code implementation was correct, however you cannot provide client names with hypens "-". Although this works when returning TwiML via a callback URL, it doesn't work via the ReST API.

The client name can only be alphanumeric and underscores.
Custom params cannot contain anything other than alphanumeric characters and underscores as well.
Custom parameters cannot have null values ex: param1=Hello&param2=&param3=World here param 2 is empty.

An example of a correct client reference would be

new PhoneNumber("client:59191ecf_263c_49eb_9b9b_b6a265ee28d8?agentFirstName=Michael&agentLastName=Scott"))

p.s. Make sure your capability token is also created with the client id without hyphens.
