+### Integration with AWS Services
+
+ Most Lambda functions are triggered by events originating in other AWS services such as `Amazon SNS`, `Amazon SQS` or `AWS APIGateway`.
+ 
+ The [Swift AWS Lambda Events](http://github.com/swift-server/swift-aws-lambda-events) package includes an `AWSLambdaEvents` module that provides implementations for most common AWS event types further simplifying writing Lambda functions.
+
+ Here is an example Lambda function invoked when the AWS APIGateway receives an HTTP request.
+
+ ```swift
+import AWSLambdaEvents
+import AWSLambdaRuntime
+
+let runtime = LambdaRuntime {
+    (event: APIGatewayV2Request, context: LambdaContext) -> APIGatewayV2Response in
+
+    APIGatewayV2Response(statusCode: .ok, body: "Hello World!")
+}
+
+try await runtime.run()
+```
+
+ You can learn how to deploy and invoke this function in [the API Gateway example README file](Examples/APIGateway/README.md).
