Appstle: Shopify Subscriptions, Loyalty & Memberships

Appstle powers subscriptions, loyalty programs, and memberships for Shopify stores. Explore our REST APIs, webhooks, Shopify Flow integrations, and storefront customization hooks.

Appstle is a suite of Shopify apps that lets you build and manage recurring revenue programs — subscriptions, loyalty points, and memberships — 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.

Get started

1. Install the Appstle app

   Install the relevant Appstle app (Subscriptions, Loyalty, or Memberships) 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.
