# Modify the Lambda function

How to modify the AWS Lambda function for the Snyk to Slack integration

{% hint style="info" %}
**Snyk is rolling out a new navigation.** The steps on this page describe the classic interface. If your view looks different, visit [Navigate the Snyk Web UI](https://docs.snyk.io/navigate-the-snyk-web-ui#where-things-moved) to map these options to the new interface.
{% endhint %}

## Modify the Lambda function

1. Open your Lambda function and click on **Configuration**.
2. Select **Function URL** and then **Create function URL**.

4. Copy the function URL to use in the next step of the guide.
5. The function URL is now ready for use and a resource-based policy has been added that you can verify under **Permissions**.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.snyk.io/developer-tools/snyk-api/using-specific-snyk-apis/webhooks-apis/guides-to-webhooks/how-to-use-snyk-webhooks-to-connect-snyk-to-slack-with-aws-lambda/aws-lambda-setup-set-up-the-trigger/with-a-lambda-function-url/modify-the-lambda-function.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
