Once you finish reading this guide, you’ll know the differences between WebSocket and Webhook. This will help you decide which one to use for your web application.

So, let’s dive in!

What are WebSocket and Webhook?

Before diving into the comparison between WebSocket and Webhook, let’s start with a brief introduction to both technologies.

WebSocket facilitates real-time, two-way communication between a server and a client by creating a persistent connection. This means that data can be exchanged continuously without requiring multiple requests.

Webhook, on the other hand, is a method of sending real-time notifications from one web application to another. It allows one application to notify another application of an event that has occurred, enabling real-time communication.

Brief History and Development

WebSocket was introduced in 2011 as a new HTML5 API, designed to provide full-duplex communication channels over a single TCP connection. Since then, it has become increasingly popular, and many modern web applications now use WebSocket for real-time communication.

While WebSocket is a relatively new protocol, Webhook has been around for a longer time, but has seen an increase in adoption in recent years due to the growing need for real-time communication between web applications, particularly with the rise of microservices architecture.

How Do They Work?

WebSocket uses a persistent connection between the client and the server, enabling real-time bi-directional communication. To accomplish this, it employs a handshake process to initiate the connection, which is then followed by an uninterrupted exchange of data between the server and the client.

Webhook, on the other hand, uses a simple HTTP POST request to send data from one application to another. The receiving application then processes the data and takes the necessary actions based on the payload.

How to Implement WebSocket in a Web Application

Implementing WebSocket in a web application requires server-side support for the protocol. The steps to do so are straightforward:

  1. Use JavaScript to create a WebSocket object on the client side.
  2. Establish a WebSocket connection with the server.
  3. Exchange data between the client and server using the WebSocket object.

WebSocket can be implemented using popular frameworks, such as Node.js, Java, and .NET.

How to Implement Webhook in a Web Application

In contrast, implementing Webhook in a web application is relatively simple. Here are the steps:

  1. Register a webhook endpoint URL in the receiving application.
  2. Configure the sending application to send data to the webhook endpoint URL.
  3. Receive and process the data sent to the webhook endpoint URL in the receiving application.

Popular web application frameworks, like Django, Flask, and Ruby on Rails, can support the implementation of Webhook.

With a basic understanding of WebSocket and Webhook, let’s dive deeper into their features and use cases.

WebSocket vs Webhook: Features Comparison

Let’s take a closer look at the key features of each technology and compare them side by side.


WebSocket is designed for real-time bi-directional communication, allowing data to be sent and received between the client and server without the need for multiple requests. Webhook, on the other hand, provides a one-way communication mechanism where data is sent from one application to another.

Data Transmission

WebSocket offers low latency data transmission and has a higher throughput rate than Webhook. It’s ideal for real-time applications that require high-speed data transmission. Webhook, on the other hand, has a higher latency rate and is better suited for applications where real-time data transmission is not essential.

Scalability and Performance

WebSocket offers better scalability and performance compared to Webhook, as it allows for persistent connections and can handle a large number of simultaneous connections. Webhook, on the other hand, is limited by the capacity of the HTTP server, and it can’t handle large volumes of traffic.


WebSocket and Webhook both offer secure communication channels. WebSocket uses the SSL/TLS protocol to encrypt the data transmission, while Webhook uses HTTPS to secure the communication channel.

Reliability and Fault Tolerance

WebSocket has built-in mechanisms to handle reconnection and retrying, making it more reliable and fault-tolerant than Webhook. Webhook relies on the HTTP protocol, which does not have built-in retry mechanisms, and it may fail if the receiving application is unavailable or overloaded.

Flexibility and Ease of Use

WebSocket is a more complex technology than Webhook, requiring more technical knowledge to implement. However, it offers greater flexibility and customization options. Webhook, on the other hand, is easier to implement and requires less technical knowledge.

Benefits of WebSocket
