We're excited to share a handful of updates that make Smile even easier to build with, whether you're an individual merchant or agency extending Smile functionality, or integrating Smile into your own app.
Here's what's new
✨ Granular API scopes & key rotation
API keys are the standard way to access Smile's REST API. They're now easier to manage, more secure, and give you fine-grained control over what each key can do. You can create multiple keys, set specific scopes, and rotate them with zero downtime.

🌟 New VIP endpoints
Two additions to our VIP Tier API:
- A new endpoint to list all tiers
- Enriched tier objects now include perks, entry rewards, and milestone rewards
Great for apps that show customers where they stand, and what they'll earn when they level up.
🧠 Ask AI how to build
The Smile developer docs now include AI-powered answers. Have a question? Just ask. From "how do I list customers" to "how do I show rewards in a mobile app," we’ll walk you through it.
🔎 Live API explorer
Our new API explorer lets you interact with endpoints directly from the docs. Plug in your API key and see live responses as you build.
📚 Developer docs, refreshed
Our docs now have a brand-new look and feel, making it easier to navigate, explore, and get started quickly.
See what partners are building
Klaviyo uses Smile's developer tools to integrate Smile loyalty functionality natively into Klaviyo Customer Hub. That means brands can now give their customers the best possible loyalty experience, directly alongside order history and product recommendations—all in one place.
