# Extending the Salesforce Lightning app

Each Salesforce Lightning implementation comes with its own business requirements and unique challenges. While the OOTB (Out of the Box) app for Salesforce Lightning can solve some of these challenges with specific configurations, sometimes the business requirements cannot be fulfilled in a configurable manner. That is, the solution requires code. To address these challenges, we provide extension points within the app. These extension points are called by the core app code and allow you to meet specific business requirements for each implementation.

This section includes information on how to [extend the Ship From Address](/salesforce-lightning/extending-the-digital-river-salesforce-lightning-app/extend-the-ship-from-address.md) and how to [extend the webhook framework](/salesforce-lightning/extending-the-digital-river-salesforce-lightning-app/extend-the-app-webhook-framework.md).

## 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.digitalriver.com/salesforce-lightning/extending-the-digital-river-salesforce-lightning-app.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.
