Shoppers today expect fast and personalized experiences – and that’s exactly what headless commerce enables.
Back in 2020, a survey by Wunderman Thompson found that 76% of online retailers planned to adopt headless architecture within a year. Fast forward, and this isn’t just a passing trend – the headless commerce market is booming, with annual growth of over 20% and a projected value of $32 billion by 2027.
And Shopify couldn't just stand by. Enter Shopify Headless Commerce which lets brands like yours create custom storefronts while relying on Shopify’s trusted backend. In this article, I’ll explain what headless commerce and Shopify Headless are all about while laser-focusing on why and how to integrate your Shopify storefront with Voucherify-powered coupons, promotions, and loyalty programs.

Headless commerce is an ecommerce setup where the front end – the part customers see and interact with, like your website or app – is separated from the back end systems that manage things like inventory, payments, and orders. This separation allows you to work on your customer-facing experience without worrying about disrupting existing systems.

Headless architecture simplifies development by allowing development teams to make changes independently, improving speed and performance for better customer satisfaction. This architecture also provides long-term flexibility, making it easier to adopt new technologies and scale globally while managing multiple stores with a unified backend.
Shopify is a leading commerce platform, trusted by millions of businesses in over 175 countries. Shopify offers an intuitive interface and a set of powerful commerce tools that make setting up and managing online stores straightforward for businesses of all sizes.
Traditionally, Shopify provided an all-in-one solution, where the front end (what customers see) and the back end (the systems managing your store) were tightly connected. But as commerce has grown more complex, Shopify introduced headless commerce to offer greater flexibility and creative control over the presentation layer, especially for enterprise-scale businesses.

Shopify headless solutions offer merchants and developers the freedom to extend store capabilities with a composable stack of third-party applications.
Hydrogen is Shopify’s React-based framework for building custom storefronts. It’s built to help developers create fast, unique, and immersive shopping experiences. Hydrogen comes with pre-built components and templates, making it easier to craft personalized designs without starting from scratch.
Oxygen is Shopify’s global hosting solution, built to support storefronts created with Hydrogen. Oxygen ensures that these custom storefronts run smoothly, no matter where your customers are located, by offering fast and reliable hosting across multiple regions.
At the heart of Shopify’s headless commerce capabilities is its Storefront API. This API acts as the bridge between the front end and the Shopify back end, enabling developers to:
Shopify’s headless commerce solution allows businesses to overcome the constraints of traditional ecommerce platforms. When integrated with tools like Voucherify, it enables the creation of customized storefronts while enhancing the shopping experience with personalized discounts, promotions and loyalty programs.
With this setup, merchants can craft tailored promotions and rewards that feel personal and engaging. Let's focus on loyalty and how the connection between Voucherify APIs and Shopify Headless enables brands to run hyper-personalized loyalty programs, while accelerating development with no extra costs.
A well-designed loyalty program can create real value for your most engaged customers, boost profit margins, and cut customer acquisition costs. But to achieve these benefits, it needs to be more than a simple add-on – it should be part of a broader loyalty strategy. Most Shopify loyalty plugins act as standalone tools, but integrating Shopify Headless with Voucherify’s powerful loyalty APIs gives you a scalable, adaptable loyalty framework that grows with your business.
Unlike hard-coded solutions that often lead to months of delays, scope creep, and spiraling costs, integrating Shopify with Voucherify streamlines the process. This efficient setup lets you skip the headaches and focus on creating a loyalty program your customers will love.
As a Shopify merchant, you need a coherent loyalty program that works nicely across both your physical stores and Shopify storefronts – a big chunk of your audience will likely use both. This is why you need a unified experience where loyalty mechanisms and rewards will work equally well in physical stores and Shopify.
A flexible loyalty program is essential for companies building a composable toolkit with best-of-breed microservices. Once integrated, your loyalty program should sync with the rest of your tech stack, connecting effortlessly with payment systems, partner platforms, online stores, physical locations, social media, and more.
Perhaps you're planning to add kiosks or launch a mobile app soon? Choosing a headless loyalty vendor for your Shopify store, lets you easily extend to new touchpoints, ensuring a consistent experience across all customer interactions.
As a comprehensive and industry-agnostic Loyalty Engine, Voucherify offers unopinionated APIs that can be used to build fully custom loyalty flows, achievements, and challenges, while at the same time hosting the rewards catalog, member data, and engagement workflows.
Designing an omnichannel integration between a loyalty and commerce engine is a daunting tasks, which involves weeks of planning and tough calls, such as:
The good news? You don’t have to build everything from the ground up. By leveraging the right tools, like Voucherify, Shopify, and Klaviyo, you can bypass much of the complexity (and cost). The same goes for selecting the right integrator, such as Omnivy, to help you define use cases and implement essential flows. That said, integration isn’t without its hurdles. Let’s dive into the key challenges you should be prepared to tackle.
The integration should center around using the Shopify customer ID (or a CDP-based ID) as the universal identifier across Shopify, Voucherify, and Klaviyo. This approach eliminates duplicate profiles and reduces the risk of lost data.
Transaction syncing should be handled in real-time via APIs, which will automatically push purchase data from Shopify to Voucherify to trigger points and rewards. While you're at it, consider paths for product returns and exchanges. For instance, when a return is processed in Shopify, the API will automatically update the customer's points balance in Voucherify.
Beyond transactions, customer data synchronization ensures that any updates to customer profiles in Shopify – such as address changes or birthday updates – will be immediately reflected in Voucherify and Klaviyo. This creates a single source of truth for customer data, maintaining consistency and accuracy across all systems.
Your data layer won't matter if customers won't be able to join, participate, and reap the benefits of your loyalty program. Thanks to Shopify's checkout extenstions (available for Shopify Plus clients), it should be quite simple to quickly spin off key loyalty views, such as loyalty wallets, gamification views (e.g., progress bars), and points simulations. Ensure that the loyalty blocks are designed to blend in with your Shopify theme, providing a cohesive look and feel that will match your brand aesthetic. Also, ensure these elements are fully responsive, providing a consistent experience across desktop and mobile devices.
Consider adding a point forecasting feature to product pages and the shopping cart to show customers how close they are to their next reward, encouraging them to add one more item to their cart to reach a points milestone. Adding Voucherify will also enhance the member experience by enabling features like location-based promotions, loyalty rewards, or offers based on past purchases.
Thanks to Shopify's Commerce Components (available in beta), it's possible to offer custom discounts and promotions through Shopify or a third-party apps to target the right promotion to the right customer. Integrating Voucherify APIs right at the checkout enables seamless inclusion of promotions – such as dynamic discounts or personalized offers – directly into your storefront for a more engaging shopping experience.
Start with your Shopify backend, where you’ll manage everything from products to payments. Even in a headless setup, Shopify’s back end remains the engine powering your ecommerce operations.
Use Shopify’s Hydrogen framework (or another front-end framework of your choice) to create a unique storefront. With Hydrogen, you can easily pull data from Shopify’s Storefront API, like product details or customer information.
Voucherify integrates smoothly with Shopify’s headless setup. You’ll need to connect the two systems via APIs. This involves:
Add Voucherify’s functionalities to your storefront. For example:
Headless commerce gives brands the flexibility to build custom storefronts and adapt quickly to changing market demands. By integrating Shopify Headless with Voucherify, you gain the ability to manage complex promotions and loyalty features across all customer touchpoints powered by Shopify.
