First, update the [source code that imports your modules](https://github.com/slackapi/bolt-js-getting-started-app/blob/main/app.js#L1) in `app.js` to require Bolt's AwsLambdaReceiver:
```javascript
// Initializes your app with your bot token
const app = new App({
token: process.env.SLACK_BOT_TOKEN,
socketMode: true, // delete this line
appToken: process.env.SLACK_APP_TOKEN, // delete this line
});
```

Next, we'll customize your Bolt app's [`receiver`](https://slack.dev/bolt-js/concepts#receiver) to respond to Lambda function events.

```javascript
const { App, AwsLambdaReceiver } = require('@slack/bolt');
```

Then update the [source code that initializes your Bolt app](https://github.com/slackapi/bolt-js-getting-started-app/blob/main/app.js#L3-L7) to create a custom receiver using AwsLambdaReceiver:
