Appy Stamp Developer Docs

Go beyond the default widget. Connect directly to the Appy Stamp loyalty engine and build exactly what you need.

JavaScript SDK

Build custom loyalty UI on your storefront or any website. The SDK is a lightweight script that gives you direct access to customer data, rewards, and redemption.

Use it to:

  • Render custom loyalty components with your own design
  • 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.

REST API

Connect Appy Stamp to external systems. Fetch and update loyalty data from your server, CRM, or custom tooling.

Use it to:

  • Sync loyalty data with your CRM or marketing platform
  • Build custom admin dashboards
  • Trigger loyalty logic from external systems (webhooks, automation)
  • Manage customers, rewards, and tiers programmatically
  • Integrate with platforms outside Shopify

API = expand Appy Stamp outside the storefront.

GraphQL API

The same loyalty engine as the REST API, through a single typed endpoint. Fetch exactly the fields you need in one round-trip against an introspectable schema.

Use it to:

  • Query customers, rewards, tiers, and activity with precise field selection
  • Award, adjust, and redeem stamps via mutations
  • Generate typed clients from the introspectable schema
  • Power dashboards and integrations with fewer round-trips

GraphQL = one typed endpoint over the whole loyalty engine.
