How to pass appsecret_proof parameter

[rv5gestao]

Hello Gabriel,

In my code:
var messageType = Convert.ToString(messageReceived["entry"][0]["changes"][0]["value"]["messages"][0]["type"]);
var name = Convert.ToString(messageReceived["entry"][0]["changes"][0]["value"]["contacts"][0]["profile"]["name"]);
string phoneNumberWhatsapp = Convert.ToString(messageReceived["entry"][0]["changes"][0]["value"]["metadata"]["display_phone_number"]);
string phoneNumberId = Convert.ToString(messageReceived["entry"][0]["changes"][0]["value"]["metadata"]["phone_number_id"]);

                var estabModel = EstablishmentBO.Get EstablishmentByWhatsappNumber(phoneNumberWhatsapp);
                var atendimentoPeloiBot = estabModel.EstabelecimentoConfiguracao.IdFormaAtendimento == 0;

                string IBot response;
                if (messageType.Equals("text"))
                {
                    var textMessageReceived = JsonConvert.DeserializeObject<TextMessageReceived>(Convert.ToString(messageReceived)) as TextMessageReceived;
                    textMessage = new List<TextMessage>(textMessageReceived.Entry.SelectMany(x => x.Changes).SelectMany(x => x.Value.Messages));

                    MarkMessageRequest markMessageRequest = new()
                    {
                        MessageId = textMessage.SingleOrDefault().Id,
                        Status = "read"
                    };

                    await whatsAppBusinessClient.MarkMessageAsReadAsync(markMessageRequest);

When "await whatsAppBusinessClient.MarkMessageAsReadAsync(markMessageRequest);" is called, it returns this error message:

Error Message: API calls from the server require an appsecret_proof argument

I haven't found a way to pass this parameter.

How can I resolve this?

Hi, does your facebook app have app secret enabled from advance settings? I have not yet tested with app secret settings.

Yes, I disabled it and it started working.
Thanks!
