How MTB Labs built a custom gift registry integration for a baby & kids retailer
A major baby and kids retailer in Latin America needed to integrate a third-party gift registry platform with their Shopify store and implement custom checkout validation for their regional address requirements.
The Challenge
Complex registry integration requirements
The retailer needed to connect a third-party gift registry platform with their Shopify store, allowing customers to create and manage registries online. The registry data needed to be displayed throughout the shopping experience using Shopify metaobjects. Additionally, their checkout required custom address validation specific to their country's addressing system—something not supported by standard Shopify checkout. The technical complexity of integrating the registry API and building custom checkout logic had stalled previous implementation attempts.
The Solution
Gift Registry API Integration I integrated the third-party gift registry platform with Shopify, building the connection layer that allows customers to create, view, and manage their registries directly from the store. The integration handles registry creation, product additions, purchase tracking, and status updates.
Shopify Metaobject Implementation I designed and implemented a custom metaobject structure to store and display registry data throughout the Shopify storefront. This makes registry information accessible in Liquid templates, enabling customers to view registry details, track purchased items, and see what's still needed—all within a seamless shopping experience.
Custom Checkout Validation I built a Shopify Function for checkout address validation, ensuring addresses match the country's specific format requirements before order submission. This prevents invalid orders from being placed and reduces customer service issues related to shipping address errors.
Comprehensive Documentation I provided detailed documentation of the integration architecture, API endpoints, and metaobject structure, making it easy for the internal team to maintain and extend the functionality as their business grows.
