Real-time communication made easy: a guide to webhooks and websockets

We must acknowledge that WebSockets and Webhooks are two extremely effective protocols that have helped redefine the concept of real-time communication and data transfer on the Internet. We’re proud to announce that Zoom has launched WebSockets in beta to bring you even more tools to help you create innovative and engaging experiences for the PEopel around the world. In this article, we discuss how you can use webhooks and websockets to enable you to deploy an application or integrate the Zoom platform to use the company’s video-based communication services, or integrate the Zoom platform into your application.

What are webhooks and websockets?

Modern applications rely heavily on webhooks and websockets to provide critical event notification services In deployment The preferably service to their users. It is possible to receive real-time notifications about events in your Zoom account using both webhooks and WebSockets and both services are available in zoom. Additionally, these platforms provide support for applications that need to respond to changes or updates as soon as those changes are made. When deciding what’s right for your use case, you should consider the key differences between webhooks and websockets, including ease of implementation, speed of deployment, reliability, architecture, etc.

Compare webhooks and web sockets

Protocols and easy implementation

Unlike WebSockets which use the WebSocket protocol (whether or wss) instead of webhooks that use HTTP. This is one of the reasons why webhooks are generally easier to set up up, there You only need an endpoint URL to receive HTTP POST requests, as opposed to an entire website. It’s more complex to set up WebSockets because you need to get an access token and open a connection to the server for them to work.

delivery speed

Due to the fact that they offer a duplex communication channel, WebSockets are typically faster at transferring data than webhooks. To enable real-time data exchange between client and server, WebSockets allow a single connection to be established between client and server without the need to make additional HTTP requests. Persistent connections often perform better than webhooks in terms of providing event notifications and consuming resources more efficiently when compared to webhooks.


When evaluating event-based communication options, it’s important to consider reliability. When an event occurs, webhooks notify a specific URL by sending a notification based on the event. If there are still problems with the endpoint, the event notification may not be processed correctly. The WebSocket protocol, on the other hand, maintains a persistent connection with the server, making communication between the client and server more secure and reliable.


There is a “push” model for webhooks, which means that according to the “push” model, Zoom will send event notifications to endpoints as they occur. To use WebSockets, the client must connect to the server and then receive event notifications as they occur, which is a “pull” model.

Stateless vs. stateful

This is because webhooks are stateless in the sense that they contain complete information about each event independently, and no state information. There is a stateful aspect WebSockets, the means that the client and server maintain a persistent connection throughout the lifetime of the connection which allows them to share state information throughout the process.

use cases

In some cases, webhooks can be a better solution than using a service-based solution when the app is only needed receive some event notifications. In our scenario, let’s take the example that you have a marketplace app that requires sending a notification when a meeting is created, updated, or deleted by a user. As you can see, webhooks are the preferably Solution in this case as the app only needs to receive a small number of event notifications (i.e. meeting-related notifications) to function properly. Implementing WebSockets has many advantages over setting up a simple endpoint that receives these notifications via webhooks.

There are many industries that use WebSockets for developing applications such as banking, finance and healthcare and this can be the case Good Options for these developers. To ensure their endpoints are secure when implementing webhooks, developers need to make extra efforts to ensure they have the request and Whitelist the IPs connected to the endpoint. A WebSocket is a secure protocol that allows direct connections between a client and the server, reducing the risk of man-in-the-middle attacks, which in turn ensures an extra layer of security over HTTP since the connection is established between the two becomes client and server directly. Since WebSockets only move data when the connection is open, they offer a more reliable connection, there Data can only be transferred when opened and will remain open until closed by the developer. The Good What’s special about Zoom WebSockets is that not only can the connection only be opened with the access token generated by the app that created the subscription, only one connection can be open at a time, meaning that only one connection can be open at any given time used. It should be noted that despite their relatively low latency, one of the main advantages of WebSockets over webhooks is their ability to communicate in real-time despite their low latency. That’s extreme important for use cases where it is important so that updates are available in good time.

Engaging experiences require the use of essential tools

WebSockets are now standard tools for building interactive web applications because they are the most widely used technology to achieve low latency, scalability, and seamless updates on the web. Zoom uses this cutting-edge technology Technologies to create an engaging and intuitive user experience. There are a variety of different Event Notifiers that can help you unlock your full potential Application, regardless of whether it is a customer loyalty system or a monitoring system.
