SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill reduces the time and confusion of building Shift4Shop (3dcart) apps by providing clear guidance for OAuth authentication, REST API integration, webhooks, and storefront customization.

Core Features & Use Cases

  • Shift4Shop API Integration (v2): Guides you to design integrations against the current REST API (including products, orders, customers, categories, manufacturers, and CRM).
  • OAuth and Token Management: Helps you implement the authorization code flow for public apps and handle token refresh for long-running services.
  • Webhooks and Template Customization: Supports event-driven updates via webhooks and explains how to customize storefront behavior using the Core Template Engine and custom JavaScript.
  • Payment/Shipping Integration Planning: Explains how to approach payment gateway modules and shipping rate integrations.

Use Case: You want to build a public Shift4Shop app that listens for order events, pulls full order details via the REST API, and then syncs fulfillment status back into the store.

Quick Start

Create a Shift4Shop public app that authenticates with OAuth, subscribes to order.created webhooks, and then fetches the full order payload from the Orders endpoint in API v2.

FAQPage Schema
How do I integrate with the Shift4Shop REST API v2 for order management?

Shift4Shop REST API v2 integration uses array-based payload conventions to manage orders, products, customers, categories, manufacturers, and CRM data. You authenticate with OAuth 2.0, handle token refresh logic, and make rate-limit-aware requests to interact with store data endpoints.

How does OAuth 2.0 authorization code flow work for public Shift4Shop apps?

OAuth 2.0 authorization code flow for public Shift4Shop apps requires secure token handling with refresh logic for long-running services. You implement the authorization flow to obtain access tokens, then use those tokens to authenticate API v2 requests for your custom integration.

What's the best way to set up Shift4Shop webhooks for order event processing?

Shift4Shop webhook-driven event processing subscribes to events like order.created, then triggers your app to fetch full order payloads via the REST API v2. This event-driven approach enables real-time updates and fulfillment status syncing back into the store.

Can I customize Shift4Shop storefront templates using the Core Template Engine?

Shift4Shop storefront customization uses the Core Template Engine and custom JavaScript to modify storefront behavior. This supports custom module development and storefront template modifications for products, categories, and the overall customer shopping experience.

Does this approach support both private single-store integrations and public Shift4Shop apps?

Shift4Shop integration supports public OAuth apps, private single-store integrations, and custom module scenarios. Public apps use the OAuth 2.0 authorization code flow, while private integrations can interact directly with API v2 endpoints for store-specific data management.

How do I handle Shift4Shop API rate limits and token refresh for long-running services?

Shift4Shop API v2 requires rate-limit-aware requests and secure token handling with refresh logic for long-running services. Properly managing OAuth 2.0 token expiration ensures your integration maintains continuous access to store data without authentication interruptions.
