Custom Loyalty Module for Dot & Key
Dot & Key needed a loyalty framework that could drive repeat purchases without being constrained by the limitations of off-the-shelf Shopify apps. Instead of adopting a plug-and-play tool, we built a custom loyalty module designed to handle scale, provide flexibility, and integrate seamlessly with their existing Shopify store and mobile app.




Problem Statement
Traditional Shopify loyalty apps came with recurring costs, limited customizability, and performance issues during peak campaigns. Dot & Key required a solution that could:
- Be deployed as a custom backend within Shopify
- Scale for large traffic spikes during launches
- Power tailored loyalty experiences instead of rigid templates
- Offer reusable infrastructure for future campaigns
- Provide custom UI elements across website and app through APIs
Features
Custom Loyalty System Built for Scale and Flexibility:
VIP Tiering
The module supports tier-based engagement with levels such as New, Rising Star, and Super Star, each offering increasing perks. This gamified system helps nurture customers and incentivize long-term loyalty.
Advanced Cashback & Discounts
The loyalty engine allows Dot & Key to configure multiple types of offers, including:
- Percentage-based cashback (e.g., 20% cashback up to ₹200)
- Flat cashback amounts
- Hybrid rules combining discounts with cashback
- Minimum order-based rewards to encourage higher cart values
Smart Rules & T&Cs
The system automatically enforces complex conditions such as:
- Cashback usage limits at checkout
- Expiry-driven reminders to improve repeat purchases
- Automatic adjustment of wallet balances in case of refunds
- Time-delayed cashback credit after order delivery
Backend Capabilities
Built on AWS, the backend offers:
- Cohort-based cashback distribution (e.g., targeting lapsed customers)
- Automated expiry and low-balance notifications
- A real-time analytics dashboard to track performance and redemption
- Modular design, making it reusable for future brand campaigns
Custom UI Across Website & App
- A wallet interface to display cashback balances
- Prominent T&C visibility to improve transparency
- Cashback shown at cart and checkout, reinforcing value before purchase
- APIs powering a unified experience across web and mobile
