In this tutorial, we'll walk through the process of setting up and using AWS API Gateway WebSocket with Python. WebSocket APIs in AWS API Gateway allow you to establish a two-way communication channel between clients (such as web browsers or mobile apps) and your backend services. We'll cover setting up the API Gateway, creating a WebSocket API, integrating it with a Lambda function, and then interacting with it using Python.
Before you begin, ensure you have the following:
You'll need the websocket-client library to interact with your WebSocket API from Python. Install it using pip:
Below is a simple Python code example demonstrating how to connect to your WebSocket API and send/receive messages:
Replace "wss://your-api-id.execute-api.your-region.amazonaws.com/prod" with the actual WebSocket API endpoint you created.
Save the Python script and run it. It will connect to your WebSocket API, send a message, and print any received messages to the console.
In this tutorial, we've covered the basics of setting up and using AWS API Gateway WebSocket

WebSocket is a communication protocol that provides full-duplex communication channels over a single TCP connection. AWS API Gateway supports WebSocket APIs, allowing you to build real-time applications with bidirectional communication between clients and servers. In this tutorial, we'll guide you through the process of creating a WebSocket API using AWS API Gateway and interacting with it using a Python client.
Before you begin, make sure you have the following prerequisites:
Open the AWS Management Console and navigate to the API Gateway service.
Click on "Create API" and choose the "WebSocket API" option.
Provide a name for your API and click on "Create API."
After creating the API, click on the "Create" button under the "Routes" section to define a new route.
Add a route for the WebSocket API, such as /chat.
Save the route configuration.
In the API Gateway console, click on the "Stages" tab.
Click on "Create Stage" and provide a name for the stage (e.g., "prod").
Deploy the WebSocket API to the stage.
To handle WebSocket events, you need Lambda functions. For this tutorial, we'll create two functions: one for handling the connection and another for handling messages.
Deploy these functions to AWS Lambda using the AWS CLI or the Lambda console.
In the API Gateway console, go to the "Integration" tab.
Create a new integration for the connection_handler Lambda function.
Repeat the process for the message_handler L
