Show stamp balances, rewards, and VIP tiers anywhere on your site
Let customers redeem rewards without the default widget
Trigger loyalty actions (social follows, reviews) from your own UI
Build loyalty features on non-Shopify platforms

SDK = build your own loyalty UI on top of Appy Stamp.

Use it to:

Sync loyalty data with your CRM or marketing platform
Build custom admin dashboards
Trigger loyalty logic from external systems (webhooks, automation)
