 To use these types, you can apply them as type annotations to your callback arguments. Here, for example, the `APIGatewayProxyEvent` and `Context` types are applied to the arguments of an inline AWS API Gateway route handler:
 
 ```typescript
+import * as aws from "@pulumi/aws";
 import * as apigateway from "@pulumi/aws-apigateway";
 import { APIGatewayProxyEvent, Context } from "aws-lambda";
 
 const api = new apigateway.RestAPI("api", {

         {
             path: "/api",
