Subtotal Connect for Shopify

The Subtotal Connect Shopify app adds account-linking to your store so customers can connect their retailer accounts (e.g., Amazon, Walmart, Sephora) and share verified purchases with you. Install the app from the Shopify App Store, then add one or both of the components below to your store.

Components

The app includes two components. Use one or both depending on your theme and whether you use the new Shopify customer accounts experience.

Theme app block

A block you add in the Shopify theme editor—typically on the Account page or another customer-facing page. It shows a list of supported retailers so customers can link, disconnect, or reauthenticate accounts. The theme app block is fully customizable: you can change copy and colors in the theme editor, and use custom CSS for advanced styling (see Customizing the theme app block below).

Profile UI extension

An extension that works with the newer Shopify customer accounts. When enabled, customers can manage their linked retailer accounts from their profile without needing the theme app block on a specific page. The profile extension uses Shopify’s default styling for the customer account area.

Customizing the theme app block

The following sections apply only to the theme app block. They do not apply to the profile UI extension.

Quick Start

In your Shopify admin, go to Online Store > Themes
Click Customize on your active theme
Navigate to the page where Subtotal Connect is placed (typically the Account page)
Click on the Subtotal Connect block in the sidebar
Adjust settings to match your brand
Click Save to apply changes

Theme editor settings

The following settings are available for the theme app block in the Shopify theme editor:

Setting	Description	Default
Heading	Main title displayed above the retailer list	”Link your retailer accounts”
Description	Subtitle text explaining the feature	”Connect your accounts to earn points when you shop in-store.”
Background color	App block container background	`#ffffff`
Text color	Primary text color for headings and retailer names	`#000000`
Accent color	Used for buttons, loading animation, and hover effects	`#000000`
Custom CSS	Advanced CSS overrides using CSS variables	Empty

@keyframes custom-slide-up {
  0% {
    opacity: 0;
    transform: translateY(30px);
  }
  100% {
    opacity: 1;
    transform: translateY(0);
  }

Staggered Card Animation

  animation-fill-mode: both;
}

.retailer-card:nth-child(1) { animation-delay: 0.1s; }

  border-radius: var(--subtotal-connect-container-radius);
}

Troubleshooting (theme app block)

CSS Changes Not Appearing

Make sure you clicked Save after adding custom CSS
Clear your browser cache and hard refresh (Cmd/Ctrl + Shift + R)
Check for CSS syntax errors (missing semicolons, brackets)
Use !important if your styles are being overridden by theme CSS

App Block Not Displaying

Ensure you’re logged in as a customer when viewing the account page
Check that the Subtotal app is properly configured
Verify the block is added to the correct page template

Styles Conflicting with Theme

If your Shopify theme’s CSS conflicts with the app block:

/* Increase specificity */
#subtotal-connect-app-block.subtotal-connect {
  /* Your styles here */
}

/* Or use !important (use sparingly) */
.subtotal-connect__heading {
  color: #000000 !important;
}

Custom CSS Field Too Small

The Custom CSS textarea in Shopify’s theme editor is small. For complex themes:

Write your CSS in a separate code editor
Copy and paste into the Custom CSS field
Keep a backup of your custom CSS locally
