If you are looking for a way to build real-time applications that can handle a large number of simultaneous connections, AWS API Gateway Websocket is the perfect solution for you. This service provides a secure and scalable way to build websockets-based applications without worrying about infrastructure management.
What is AWS API Gateway Websocket?
AWS API Gateway Websocket is a fully managed service that allows you to create and manage websockets-based APIs at scale. With this service, you can easily build real-time applications that can handle thousands of simultaneous connections. Unlike traditional REST APIs, websockets-based APIs provide a persistent connection between the client and the server, allowing for bi-directional communication in real-time.
How does it work?
When a client establishes a connection with an AWS API Gateway Websocket endpoint, it sends a WebSocket handshake request to the server. The server then responds with a WebSocket handshake response, and the connection is established. Once the connection is established, the client and server can exchange messages in real-time.

- Security: AWS API Gateway Websocket provides a secure way to build websockets-based APIs, with support for authentication and authorization.
- Easy to use: AWS API Gateway Websocket is easy to use and requires no infrastructure management on your part. You can focus on building your application instead of managing servers.
- Real-time communication: With websockets-based APIs, you can build real-time applications that provide a seamless user experience.
Getting started with AWS API Gateway Websocket
Step 1: Create an API Gateway WebSocket API
The first step to using AWS API Gateway Websocket is to create an API Gateway WebSocket API. To do this, follow these steps:
- Open the API Gateway console.
- Click on “Create API”.
- Select “WebSocket API” as the API type.
- Enter a name for your API and click on “Create API”.
Step 2: Create a WebSocket route
After creating the WebSocket API, you need to create a WebSocket route that will handle incoming messages. To do this, follow these steps:
- In the API Gateway console, click on your API.
- Click on “Create Route”.
- Enter a route key for your route. This can be any string that uniquely identifies your route.
- Select the integration type for your route. This can be a Lambda function, an HTTP endpoint, or a WebSocket endpoint.
- Click on “Create Route”.
Step 3: Deploy your WebSocket API
After creating your WebSocket API and route, you need to deploy your API to make it available to clients. To do this, follow these steps:
- In the API Gateway console, click on your API.
- Click on “Actions” and then click on “Deploy API”.
- Select the deployment stage for your API.
- Click on “Deploy”.
Step 4: Connect to your WebSocket API
After deploying your WebSocket API, you can connect to it using a WebSocket client. To connect to your WebSocket API, follow these steps:
- Get the WebSocket URL for your API. This can be found in the “Stages” tab of your API Gateway console.
- Use a WebSocket client to connect to the WebSocket URL.
- Send messages to your WebSocket API using the WebSocket client.

FAQ
What is a WebSocket?
A WebSocket is a protocol that provides a persistent connection between the client and the server, allowing for bi-directional communication in real-time.
What is the difference between REST APIs and websockets-based APIs?
REST APIs provide a request-response model, where the client sends a request to the server and the server sends a response back to the client. Websockets-based APIs provide a persistent connection between the client and the server, allowing for bi-directional communication in real-time.
What are the benefits of using AWS API Gateway Websocket over traditional websockets?
AWS API Gateway Websocket provides a fully managed service that can handle a large number of simultaneous connections, making it ideal for real-time applications that require high scalability. It also provides a secure way to build websockets-based APIs, with support for authentication and authorization.
What are the pricing options for AWS API Gateway Websocket?
AWS API Gateway Websocket is priced based on the number of messages sent and received by your API. The first 1 million messages per month are free, and after that, you pay $1.00 per million messages.
Can I use AWS API Gateway Websocket with other AWS services?
Yes, AWS API Gateway Websocket can be integrated with other AWS services, such as AWS Lambda, Amazon DynamoDB, and Amazon SNS.
