Welcome to the RingCentral Community

@Carl McFarland Please go through below article about RingCentral .NET SDK 5 which supports extensions:

https://medium.com/ringcentral-developers/ringcentral-net-sdk-5-0-and-its-extensions-2992a5dc5caa

Check the Events extension:

https://github.com/ringcentral/RingCentral.Net/tree/master/RingCentral.Net.Events

RingCentral .NET SDK 5.x has major changes and there are many source breaks. It supports SDK extensions mechanism. And to catch the events, create and install the EventsExtension as shown below:

RestClient rcsdk = new RestClient(RC_CLIENTID, RC_CLIENTSECRET, RC_PRODUCTION);
rcsdk.Authorize(RC_USERNAME, RC_EXTENSION, RC_PASSWORD).Wait();
var eventsExtension = new EventsExtension();
rcsdk.InstallExtension(eventsExtension).Wait();
eventsExtension.RequestSuccess += EventHandler;
...
static void EventHandler(object sender, HttpMessages httpMessages)
{
    var rateLimitRemaining = httpMessages.httpResponseMessage.Headers.First(i => i.Key == "X-Rate-Limit-Remaining").Value.First();
    Console.WriteLine("Remaining: " + rateLimitRemaining);
}

This does not work in RingCentral.net SDK version 5.2. The AfterHTTPCall event does not exist.

Hi Phong Vu,

I don't see AfterHttpCall in my ringcentral DLL. (Assembly RingCentral.Net, Version=1.0.0.0)

I am using Nuget Packaage.

Am I missing something...

Hi,

Please check the below link

https://medium.com/ringcentral-developers/ringcentral-api-rate-limit-explained-2280fe53cb16

Using the RingCentral .Net SDK, you can check API limit header as shown below:

static RestClient rcsdk;

static void Main(string[] args)
{
  rcsdk = new RestClient(RINGCENTRAL_CLIENTID, RINGCENTRAL_CLIENTSECRET, RINGCENTRAL_PRODUCTION);
  rcsdk.Authorize(RINGCENTRAL_USERNAME, RINGCENTRAL_EXTENSION, RINGCENTRAL_PASSWORD).Wait();
  rcsdk.AfterHttpCall += EventHandler;
}
static void EventHandler(object sender, HttpCallEventArgs eventArgs)
{
  var rateLimitRemaining = eventArgs.httpResponseMessage.Headers.First(i => i.Key == "X-Rate-Limit-Remaining").Value.First();
  Console.WriteLine("Remaining: " + rateLimitRemaining);
}
