Appstle is a suite of Shopify apps that lets you build and manage recurring revenue and merchandising programs — subscriptions, loyalty points, memberships, and product bundles — all backed by enterprise-grade REST APIs. Whether you’re automating workflows, building a custom customer portal, or integrating with third-party tools, Appstle gives you the programmatic access you need.

Subscriptions

Manage recurring subscription contracts, billing, and customer self-service portals.

Loyalty

Power points programs, VIP tiers, referrals, and reward redemptions.

Memberships

Create tiered memberships with gated content and access control.

Bundles

Build product bundles and Build-a-Box experiences with dynamic discounts.

​
Get started

1

Install the Appstle app

Install the relevant Appstle app (Subscriptions, Loyalty, Memberships, or Bundles) from the Shopify App Store on your store.
2

Get your API key

In your Appstle admin panel, navigate to Settings → API Key Management and create your first API key. Copy it immediately — it’s only shown once.
3

Make your first request

Pass your API key in the X-API-Key header and call any endpoint. See the quickstart guides for your first working request.
4

Set up webhooks (optional)

Configure real-time event notifications in Settings → Webhooks to react to subscription, loyalty, and membership events in your systems.

Appstle Admin APIs authenticate with an X-API-Key header — create and manage your keys from Settings → API Key Management in your Appstle admin panel. Storefront and Customer Portal APIs run through Shopify’s App Proxy and use the logged-in customer session instead.
