What problem does it solve?

This Skill helps you connect external systems to Squarespace Commerce and customize storefront behavior safely despite Squarespace’s constrained extension model.

Core Features & Use Cases

• Commerce API integration (orders, transactions, products, inventory, profiles): Build external services that read commerce data, update inventory, and fulfill orders using the REST API with cursor pagination.
• Secure authentication & authorization: Choose API Keys for single-site integrations or OAuth 2.0 for third-party apps needing access across multiple sites, including token refresh handling.
• Frontend customization via injection: Add site-wide or per-page CSS/JS/HTML using code injection, and use Fluid Engine layouts or (legacy) JSON-T templates where applicable.
• Webhook-driven automation: Subscribe to real-time events (e.g., order.create, order.update) and design receivers that verify payloads and fetch full entities via API.

Quick Start

Ask Claude to create a backend integration that receives Squarespace order webhooks, fetches the full order from the Commerce API, and then triggers your fulfillment workflow using OAuth 2.0 tokens.
