Tech Stack Used

Shopify Payments API, JoinFam API, Node.js, Shopify Admin API, Checkout Extensions, Encryption protocols

Challenge

JoinFam APIs needed clean integration with Shopify
Security and PCI compliance were essential
Checkout had to stay fast on every device
Errors needed graceful handling to avoid lost sales
Multi-currency support was a requirement

Approach

We began with a discovery phase to understand how FamPay's teen-first payment model needed to translate into a Shopify-compatible experience. Our team designed the app flow to keep onboarding simple for both parents and teen users, with clear approval flows. Development involved building the Shopify payment app using the Shopify App Bridge and FamPay's API, ensuring secure and seamless checkout integration. Testing was conducted across Shopify store types before App Store submission.

Solution Delivered

We built a Shopify payment app that links JoinFam to any Shopify store with minimal setup. Merchants install the app, connect their JoinFam account, and start accepting payments. Checkout stays fast. Errors are handled cleanly. Multi-currency support works out of the box.
