I'm trying to send a template message in C# using the WhatsApp Cloud API, I succeeded to send message when I used a template without any parameter:

{
    "messaging_product": "whatsapp",
    "to": "{{Recipient-Phone-Number}}",
    "type": "template",
    "template": {
        "name": "hello_world",
        "language": {
            "code": "en_US"
        }
    }
}

To C# (Working)

var request = new HttpRequestMessage
{
    Method = HttpMethod.Post,
    RequestUri = new Uri(".0/596008323xxxxxx/messages"),
    Headers =
    {
        { "Authorization" , access_token}
    },
    Content = JsonContent.Create(new
    {
        messaging_product = "whatsapp",
        to = "21xxxxxx",
        type = "template",
        template = new
        {
            name = "hello_world",
            language = new {code = "en_US"}
        }
    })
};

But in another Whatsapp template I used two parameters, So I failed to apply the parameters in C# code

This is working API

{
    "messaging_product": "whatsapp",
    "to": "{{Recipient-Phone-Number}}",
    "type": "template",
    "template": {
        "name": "new_template",
        "language": {
            "code": "en_US"
        },

        "components": [
        {
        "type": "body",
        "parameters": [
                {"type": "text", "text":"person_name"},
                {"type": "text", "text":"15"}
            ]
        }]
    }
}

Not Wotrking C#

var request = new HttpRequestMessage
{
    Method = HttpMethod.Post,
    RequestUri = new Uri(".0/596008323xxxxxx/messages"),
    Headers =
    {
        { "Authorization" , access_token}
    },
    Content = JsonContent.Create(new
    {
        messaging_product = "whatsapp",
        to = "21xxxxxx",
        type = "template",
        template = new
        {
            name = "new_template",
            language = new {code = "en_US"},
            components = new 
            {
                type = "body",
                parameters = new
                {
                    text = "person_name",
                    text2= "15"
                }
            }
        }
    })
};
