Using directives in Store Builder

Use directives to display live product and order data in your HTML without writing custom JavaScript or calling the FastSpring API. You can use directives to dynamically show values like product names, images, prices, discounts, and order totals.

Why use directives?

Display live product and order data in your HTML without writing JavaScript:

No custom JavaScript required: Populate dynamic values using HTML attributes only
Real-time updates: Show live pricing, cart, and order data as the buyer interacts
Minimal setup: Add FastSpring-powered content without managing API responses

What this guide covers

This guide explains how to:

Use product-level directives like data-fsc-item-display and data-fsc-item-price
Use order-level directives like data-fsc-order-total and data-fsc-order-country

Quick start

Follow these steps to add directives to your Store Builder integration:

Add the Store Builder script

<!-- Load the FastSpring Store Builder script -->
<script
  id="fsc-api"
  src="https://sbl.onfastspring.com/sbl/1.0.3/fastspring-builder.min.js"
  type="text/javascript"
  data-storefront="your-storefront-URL">
</script>

Replace your-storefront-URL with the full path to a checkout in your store.

Use a directive in your HTML

Here’s how to display a product’s name using data-fsc-item-display:
```

<span data-fsc-item-path="your-product-path" data-fsc-item-display></span>
```
What it does: Renders the display name of the product in this span
What to update: Replace your-product-path with the path of a product from your store

Product-level directives

Product-level directives allow you to fetch and display dynamic information for a single product using HTML attributes. These directives can be used to show product names, images, prices, descriptions, and more without making API calls.

Requirements

Before using product-level directives, make sure you:

Include the FastSpring Store Builder script

Click to view script

<script 
    id="fsc-api"
    src="https://sbl.onfastspring.com/sbl/1.0.3/fastspring-builder.min.js"
    type="text/javascript"
    data-storefront="your-storefront-URL">
</script>

Replace your-storefront-URL with the full path to a checkout in your store.

Attribute	Description
`id`	Identifies the script block (must be set to `fsc-api`)
`src`	Specifies the version of the Store Builder
`type`	Declares the script as JavaScript
`data-storefront`	The storefront URL this script will connect to

Add the data-fsc-item-path attribute to each product element
This tells Store Builder which product to pull data from.
Use product paths that exist in your store checkout
Directives will only populate if the product was added to the homepage of your checkout.

FAQs

My product directive isn’t working. Why?

This usually means the product isn’t added to the homepage of the checkout you linked to in data-storefront. Even if the product is in the checkout, it must be available on the homepage for directives to work.

What happens if I don’t specify a product path?

If the data-fsc-item-path attribute is missing, the product-level directives will not retrieve data, and the element will remain empty.

How do I test directives before deploying?

Use your browser’s developer tools to inspect elements and verify that the directives are pulling the correct data from your FastSpring store.
