Javascript » PHP » Python » Ruby » Java » C# »

What are events, notifications and subscriptions?

  • Events - events are synonymous with notifications, and refer to a message that is sent after it is triggered by an action, or state-change on the platform.

  • Subscription - a subscription refers to how an event notification is delivered to an application. A subscription contains the following metadata:

  • How the event is delivered, e.g. via webhook, pubnub, APNS, etc.
  • Address - where the notification is delivered
  • Expiry - when the subscription will end
  • The set of events being listened for/subscribed to

How do I create a subscription, or a webhook?

Webhooks and subscriptions in general are created exclusively via the Subscription API. There is no web interface or developer console for creating/registering webhooks.

When should I use a webhook vs PubNub?

RingCentral supports two primary means for delivering events/notifications: via a webhook and via PubNub. Here are considerations to make when deciding which to support in your application:

  • With assistance from RingCentral code samples, PubNub notifications are the quickest and simplest to implement, especially when you don't already have a webserver setup and running.
  • Webhooks are great if your service is "always on" and needs to receive notifications even if clients are offline.
  • PubNub is ideal for delivering low-latency notifications that must be sent directly to clients, e.g. push notifications for mobile applications.
  • Webhooks can be implemented at no additional cost, as PubNub is a service independent from RingCentral.
