Defining callbacks like this
```export async function myLambda(
    event: awsx.apigateway.Request): Promise&lt;awsx.apigateway.Response&gt; {```

```
new aws.lambda.CallbackFunction(name,
        {
            policies: [aws.iam.ManagedPolicy.AWSLambdaBasicExecutionRole, aws.iam.ManagedPolicy.AWSLambdaDynamoDBExecutionRole],
            callback: f
        },)```
my gateway
```aws.apigateway.RestApi```
Then i go on to define a custome resource which inside does a

```resource

method(dependsOn:[lambda, resource])

integration(dependsOn:[lambda,resource,method]```

and finally a deployment depending on my custom resource for the route.

Found it

needed to define an `aws.lambda.Permission` for the api to invoke the lambda.
