# Overview

It is also welcome if you wish to do the pure integration by yourself.  For pure integration, you need to create API endpoints and data objects by yourself.

{% hint style="warning" %}
Smarts recommends [**Spring Boot Starter** ](https://developer.smarts.ee/integration/spring-boot-starter/overview)integration which generates API-s and data objects **automatically**.
{% endhint %}

*There is minimum **3 steps** to get your store up and running.*
