Dear Team, I have been able to test some of the functionalities of the RingCentral system and I am fine with it.
However, i am still having some challenges with the webhook API.
I followed the instruction on the website to set up a web hook api for our proposed fax system.
However I am not receiving any notification on the web hook end point as expected. Please tell me what I am doing wrong. My web hook end point is called createsubscription(for you to kindly look up). Please see all my code snippets below
StartUp
app.Run((context) =>
{
context.Request.Headers.TryGetValue("Validation-Token", out StringValues validationToken);
context.Response.Headers.Add("Validation-Token", validationToken);
if (context.Request.Path == "/webhook" && context.Request.Method == "POST")
{
using (StreamReader reader = new StreamReader(context.Request.Body, Encoding.UTF8))
{
var str = reader.ReadToEndAsync();
Console.WriteLine(str);
}
}
return Task.CompletedTask;
});
//Program Class
public class Program
{
static RestClient restClient;
const string DELIVERY_ADDRESS = "https://e889-96-73-205-2.ngrok.io/ringcentral/hook";

Console.WriteLine("WebHook ready!");
}
