Integrating Referral Programs with Shopify: A Complete Guide
Integrating a referral program directly within Shopify ensures a frictionless experience for both your existing customers and their friends. With the right setup, you’ll drive higher participation, accurate tracking, and fully automated payouts via UPI. This guide covers everything you need to get started.
1. Why Shopify Integration Matters
Frictionless UX: Embedding widgets on order status and account pages captures customers at peak engagement moments.
Accurate Attribution: Native integration tracks clicks, shares, and conversions without gaps.
Automated Payouts: Instant UPI cashback via RazorpayX streamlines reward fulfillment and boosts brand trust.
2. Install & Configure Your Shopify Referral App
A. Choose & Install Your Referral App
Select from Shopify App Store: Search for a referral app that supports UPI or custom payout integrations.
Grant Required Permissions: Ensure the app has read/write access to Orders, Customers, and ScriptTag APIs.
B. Initial Setup
API Credentials: Enter your referral platform’s API key and secret in the app’s settings page.
Brand Customization: Configure brand colors, logo, and default copy for “Refer & Earn” buttons.
3. Embedding the Referral Widget
A. Thank-You (Order Status) Page
Go to Online Store › Themes › Customize.
Select Order status page.
Add a Custom Liquid section and paste the widget snippet provided by your referral app.
Save and preview to confirm the widget appears immediately after purchase confirmation.
B. Customer Account Dashboard
In the theme editor, choose Customers account.
Add the same widget snippet or use the app’s built-in “Referral” section.
Ensure the widget displays referral link, share buttons (WhatsApp, Email), and reward details.
4. API & Webhook Configuration
A. ScriptTag Injection
The referral app injects a small JavaScript bundle into your storefront pages via Shopify’s ScriptTag API. This bundle handles link generation and share-button rendering in real time.
B. Webhook Setup
In your referral app dashboard, subscribe to orders/create and orders/fulfilled events.
Configure the webhook URL to point to your referral platform’s endpoint.
On orders/fulfilled, implement logic to verify return-window completion before triggering payout.
5. Automating UPI Cashback via RazorpayX
Connect RazorpayX Account:
Enter your RazorpayX API keys in the referral app’s payout settings.
Payout Trigger:
Once the return window for the referred order closes, the referral platform calls RazorpayX’s payout API to credit the referrer’s UPI address instantly.
Confirmation & Notifications:
Referrers receive an SMS or WhatsApp notification confirming their cashback has been credited—boosting satisfaction and encouraging repeat referrals .
