-## Websocket API Gateway acknowledgement for $connect route.
 
-The Serverless Application Model (SAM) template deploys an Amazon WebSocket API Gateway and two AWS Lambda functions. When a client connects, the API Gateway creates a $connect route with Lambda proxy integration. The first Lambda function processes the initial connection, capturing both the Connection ID and API Gateway stage URL, then asynchronously triggers the second Lambda function. This second function validates the Connection ID and, if valid, uses SDK API calls to send a greeting message back to the client.
