Webhook (Events API)
If you prefer events to be pushed to you instead, we recommend using the HTTP-based Events API instead. and we'll deliver them with security, and We will even retry if things don't work out.
We have created a sample application that demonstrate how to create a WebHook receiver endpoint using ASP.NET, and the source code for the sample application is also available on GitHub.Real Time Messaging API (RTM API)
The Real Time Messaging API is a WebSocket-based API that allows you to receive events from Noah in real time. With the RTM API your app connects to Noah an receive events – this should only be used for supporting Real Time notifications to users to support the user experience. If your integration requires your app to receive all events you should use the Events API.
Subscribing to event types
On the App Portal under the "Event Subscriptions" configuration page you'll be able to select all the event types you want to subscribe to.
Important!:
Your Request URL might receive many events and requests. Consider decoupling your ingestion of events from the processing and reaction to them.
