A loyalty API connects loyalty features—such as points, rewards, referrals, and tiers—to the tools and platforms you already use. Businesses can use APIs to build more flexible and customized loyalty programs across online stores, apps, and other customer touchpoints and support personalized rewards and loyalty workflow automation.
Customers increasingly expect loyalty experiences to feel personalized. Deloitte research found that 73% of shoppers want personalized loyalty rewards, yet only 45% of brands offer them. According to the study, brands with more advanced personalization capabilities reported greater improvements in customer engagement and satisfaction, average order value (AOV), and customer lifetime value (CLV).
Learn how loyalty APIs work and explore which loyalty API tools and platforms can help you automate and customize customer loyalty experiences.
What is a loyalty API?
A loyalty API is a set of application programming interfaces that let you connect loyalty program functionality to different systems and customer experiences. APIs allow different platforms to communicate so that loyalty data can move between ecommerce stores, apps, point-of-sale (POS) systems, customer relationship management (CRM) tools, and marketing software.
Instead of managing loyalty as a separate system, a loyalty API allows businesses to integrate loyalty features into the customer journey.
For example, APIs can help businesses:
-
Award points automatically after purchases
-
Track customer loyalty tiers and rewards
-
Sync loyalty balances and reward redemption across channels
-
Trigger customer referral rewards
-
Generate coupons or personalized offers
-
Update customer profiles in real time
Loyalty API tools and platforms
The right loyalty API often depends on your business’s size, technical resources, sales channels, and business model. Businesses that want to launch quickly may prefer prebuilt platforms with API extensions; businesses with development capabilities that want deeper control over loyalty logic, data, and customer experiences may benefit from API-first platforms, which are designed to let developers build loyalty experiences from the ground up.
Here are six loyalty API tools and platforms to consider:
Yotpo
Yotpo manages loyalty campaigns across your online store and other systems, letting you reward customers for purchases, reviews, social engagement, and other activities while also giving birthday and anniversary incentives.
Yotpo includes features like Yotpo Spotlight, which distributes rewards and incentives throughout the customer journey. Basic purchase-based earnings rules, communication, and reporting features are available across all plan tiers; advanced earnings rules, such as rewards for email or SMS text message sign-ups, and advanced program settings are available only on higher tiers.
Yotpo’s loyalty API lets brands connect loyalty programs, rewards, referrals, and customer data to various external business systems. It also has webhooks, which automatically send updates when loyalty events occur, such as customers earning points or redeeming rewards. Some advanced integrations are limited to higher-level plans.
Pricing: Yotpo offers three plans: Free, Pro ($199 a month), and Premium (custom quoted).
Smile.io
Smile.io provides loyalty systems for ecommerce businesses that want built-in loyalty functionality without heavy development work. Businesses can create points programs, referral rewards, and bonus point events. The app includes integrations with platforms like Klaviyo (email marketing) and Judge.me (reviews management). Higher-level plans offer VIP status for dedicated customers, a loyalty hub, and advanced reporting and security features.
Smile’s API is designed for businesses working with developers to build more customized loyalty experiences and integrations. The API only works with Shopify or BigCommerce ecommerce platforms, and access is only available on Smile’s two highest-level plans. The platform doesn’t include webhooks that automatically send live data from one system to another, which may limit real-time loyalty automations between Smile and external systems.
Pricing: Smile.io offers four plans: Standard ($79 per month), Growth ($199 per month), Plus ($799 per month), and Enterprise (custom quoted).
LoyaltyLion
LoyaltyLion is a Shopify-focused loyalty platform designed for brands that want more tailored loyalty experiences as they grow. Businesses can create customized loyalty pages, reward purchases, referrals, and other activities, and set up automated loyalty emails. The platform has a full suite of reporting and analytics features and offers bonus point campaigns, cross-store loyalty rewards, and AI campaigns on higher-level tiers.
LoyaltyLion’s API, which is available in all plans, lets businesses sync orders and customer activity, manage loyalty points and customer profiles, and trigger loyalty rules across connected systems. The platform also has a headless API option that enables developers to build a custom loyalty program user interface on headless ecommerce architecture, where the storefront is separated from the back-end system.
Pricing: LoyaltyLion has three plans, starting at $199 a month.
Voucherify
Voucherify is an API-first incentive and loyalty platform that combines loyalty programs, personalized promotions, referrals, coupons, wallets, gift cards, and gamification within a single system. The app supports multicurrency loyalty programs and members-only promotions, and has flexible tools for testing and optimizing loyalty incentives.
The platform also emphasizes developer tools and scalable data models for businesses building more customized loyalty and promotion workflows. API limits, including total calls per billing cycle and requests per minute or hour, scale with plan tiers.
Pricing: Voucherify offers three plans: Business ($650 per month), Organization ($1,300 per month), and Enterprise (custom quoted).
Open Loyalty
Open Loyalty’s API-first loyalty and gamification platform includes points systems, tiers, referrals, wallets, coupons, badges, challenges, leaderboards, and other gamification mechanics. It is designed for businesses building highly customized loyalty programs.
Open Loyalty emphasizes event-driven architecture, custom event schemas, and developer-friendly integrations through APIs, webhooks, and modular loyalty components that connect with ecommerce, CRM, and marketing systems. The platform has just one plan, which includes full API access, no limits to features, and regular feature updates.
Pricing: Open Loyalty requires a custom quote. Pricing is based on a platform fee and an allowance fee based on the number of members who perform at least one loyalty activity per month.
Antavo
Antavo is another API-first loyalty platform built around headless and modular loyalty architecture. The platform supports points programs, tiered loyalty systems, gamification, referrals, and omnichannel customer experiences.
Antavo includes standalone, modular APIs—including Event APIs, Rewards APIs, Customers APIs, and Display APIs—that let brands build custom loyalty experiences while it manages the underlying infrastructure via its cloud-based Antavo Loyalty Engine. The platform emphasizes integrations with enterprise systems such as CRMs, customer data platforms, POS systems, and marketing automation tools.
Pricing: Antavo offers three plans, all with custom quotes based on customer activity.
Using loyalty APIs with Shopify
Shopify store owners can use loyalty APIs through both direct integrations and the ecommerce platform’s built-in automation tools. Many loyalty programs, including Yotpo, Smile.io, and LoyaltyLion, have Shopify apps with built-in APIs and integrations.
Shopify Flow can help you automate loyalty workflows without custom coding by connecting loyalty apps to Shopify events and customer actions. Depending on the loyalty platform, you can use triggers such as “Customer has enough points for reward” or “Customer moved up a tier” to launch automated workflows. Shopify Flow also automates loyalty-related actions such as “Add points” and “Deduct points.”
Shopify also provides prebuilt workflow templates for common loyalty automations. Examples include workflows that reward loyalty points and tag customers who add a tip during checkout or track and reward customers based on lifetime spend. These templates can help you launch more advanced loyalty automations without building workflows from scratch.
Loyalty API FAQ
How is a loyalty API different from a loyalty program?

Not every ecommerce business needs a loyalty API. Many businesses use prebuilt loyalty apps that provide ready-made loyalty features with minimal set-up. However, brands with more complex loyalty requirements, omnichannel operations, or custom experiences may use APIs to create more flexible integrations and workflows.
What can you build with a loyalty API?
Businesses can use loyalty APIs to build:
- Points and rewards systems
