How This App Works
This Shopify app will apply an order-level discount percentage of your choosing to an order when placed through the Tapcart app.
Considerations
To make this discount one-time only, the app checks for the customer tag App exclusive discount used so the user has to be signed into their account in app for the discount to apply. If this tag is present, the customer is not eligible for another discount and it will not be applied.
Installation Instructions
You can install the app in Shopify here.
After installing the app from the Shopify App Store you will be navigated to the app’s screen.
Choose the name for your discount and click “Create Discount” (default value is “App Exclusive Discount”).
After the discount is created you will see an interface to update the discount percentage. Set the value between 0 and 100.
Setup Shopify Flow
To make the discount one-time user only, you will also need to create a Shopify Flow:
Start when: order created, then
Check if: automatic discounts application title is equal to the name of your discount (e.g. “App Exclusive Discount”), and customer tag “App exclusive discount used“ (case sensitive) is not present, then
Add customer tag: “App exclusive discount used” (case sensitive).
Create a custom block
Add this custom block to either the Cart (if already on React) or home page. This simple block adds the sales-channel: tapcart cart attribute automatically after 500ms.You can copy and paste this directly into a new custom block in your dashboard.
import * as React from "react";
// https://docs.tapcart.com/docs/app-actions#cartupdateattributes
export default function AutoSetCartAttributesBlock({ blockConfig, useActions, __tapcartDashboard }) {
const webbridgeActions = useActions();
// Using useEffect to trigger the navigation after component mounts
React.useEffect(() => {
// Add a small delay to ensure the app is fully loaded
const timer = setTimeout(() => {
// Set cart attribute
webbridgeActions.action?.("cart/updateAttributes", {
attributes: [{key: 'sales-channel', value: 'tapcart'}]
});
}, 500) // 500ms delay for reliable execution
// Clean up the timer if component unmounts
return () => clearTimeout(timer)
}, []) // Empty dependency array means this runs once after initial render
if (__tapcartDashboard) {
return <div className="p-4">Auto Add Sales Channel Cart Attribute (No UI)</div>;
}
// Return null to make the component invisible (no rendering)
return null;
}
