You can use the Shopify Buy Button JS library to embed customizable Shopify UI components, such as product listings and shopping carts, directly into any website. The library uses the [JS Buy SDK](/docs/storefronts/headless/additional-sdks/js-buy) to connect to a Shopify store, giving you access to its products and collections.

## Requirements

- You've created a [development store](/docs/api/development-stores) or have a production store.
- You've created [products](/docs/api/storefront/reference/products/product) or [collections](/docs/api/storefront/reference/products/collection) in your store.
- You have a website and want to add ecommerce functionality to it.

## Step 1: Generate an access token

To generate an access token, you can [generate one in the Shopify admin](/docs/apps/build/authentication-authorization/access-tokens/generate-app-access-tokens-admin). Alternatively, you can create a custom app and use [authorization code grant](/docs/apps/build/authentication-authorization/access-tokens/authorization-code-grant).


## Step 2: Make your products and collections available

After you've generated an access token, you need to make products and collections available to your custom app to access them from your app. After the products and collections are available, you can retrieve them using their respective IDs.

> Tip:
> If you have many products or collections, then you can use [bulk actions](https://help.shopify.com/manual/shopify-admin/productivity-tools/bulk-actions) to make them available in one step.

### Make a collection available
