# How to Use the JavaScript SDK with Amplify Platform

## **What is the JavaScript SDK?**

The **JavaScript SDK** is a browser-based API provided by Amplify that allows developers to access real-time store and bundle information. This SDK enables developers to create custom storefront designs and behavior by integrating advanced logic, event handling, and dynamic interactions.

## **How It Works**

* The JavaScript SDK acts as a bridge between the Amplify Platform and the storefront, providing structured data that developers can use to implement dynamic and customized experiences.
* It is available **only for** [**Amplify One customers**](https://heyamplify.com/pricing/), and merchants must contact the sales team to enable access.
* Developers can use this SDK to modify the way Amplify widgets interact with the store, allowing for advanced styling and custom logic.

## **How to Use the JavaScript SDK**

If you're interested in using the JavaScript SDK:

1. **Ensure you're on the Amplify One plan.** If you are not, [reach out to our sales team ](https://heyamplify.com/?open-demo-popup=true)to discuss upgrading.
2. **Access the API documentation** (not publicly available—[contact our support team](https://support.heyamplify.com/bundles-and-upsell/how-to-contact-support) for details).
3. **Integrate the SDK** in the storefront and modify bundle behavior.

## **Important Notes**

* This SDK is **not a direct customization tool for merchants**—it is meant for developers who wish to integrate dynamic behaviors into their store.
* The resources are constantly expanded to satisfy any scenario. If you have a custom behavior, design, etc. that you want to implement into Amplify bundles, you can [**contact our support team**](https://support.heyamplify.com/bundles-and-upsell/how-to-contact-support) to learn more.
