## About Product Recommendations System

Product Recommendations System is a feature that tailors [Start Here](/haut.ai/readme.md#product-item) suggestions to each user's unique skin analysis results. Our Recommendations System can be used:

* in [Consumer Apps](/haut.ai/haut.ai-features/consumer-apps.md) (for Advanced+ plan)
* via API (for Professional plan)

Product Recommendations System:

* uses the output of [Algorithms](/haut.ai/haut.ai-features/algorithms.md) to identify the correct skin type and correct skin concerns.
* uses [Product Inventory](/haut.ai/haut.ai-features/product-recommendation-system-1.0-deprecated/product-inventory.md) to store and maintain the imported product items from your web store.
* uses [Product Shelf](/haut.ai/haut.ai-features/product-recommendation-system-1.0-deprecated/product-shelf.md) interface to match the product items with predefined skin concern categories.

## 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.saas.haut.ai/haut.ai/haut.ai-features/product-recommendation-system-1.0-deprecated.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.
