SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides secure, reliable handling of Shopify webhook events to prevent unauthorized requests, duplicate processing, and missed deliveries while enabling near-real-time syncing and GDPR-compliant data lifecycle handling.

Core Features & Use Cases

  • Programmatic webhook registration using the Admin GraphQL API so subscriptions are re-registered after OAuth or reinstall.
  • HMAC-SHA256 verification with timing-safe comparison and raw-body parsing to authenticate incoming payloads.
  • Idempotent background processing that records X-Shopify-Webhook-Id and enqueues work to avoid duplicate side effects.
  • GDPR and uninstall handlers that acknowledge requests and perform required data deletion or reporting.
  • Operational guidance for monitoring delivery failures, cleaning up stale subscriptions, and using pub/sub for high-volume delivery.

Quick Start

Send me a concise checklist to register Shopify webhook topics (including GDPR and APP_UNINSTALLED), verify HMAC using the raw request body, and implement idempotent order processing that enqueues jobs for background handling.

Frequently Asked Questions about shopify-webhooks

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I verify Shopify webhook HMAC signatures securely?▼

Verify Shopify webhooks by computing HMAC-SHA256 using the raw request body and comparing the result with timing-safe comparison to authenticate incoming payloads and prevent unauthorized requests.

What's the best way to prevent duplicate Shopify webhook processing?▼

Prevent duplicate Shopify webhook processing by recording the X-Shopify-Webhook-Id header to enforce idempotency, ensuring repeated event deliveries do not trigger duplicate side effects in your system.

How do I register Shopify webhook subscriptions programmatically?▼

Register Shopify webhook subscriptions programmatically using the Admin GraphQL API so subscriptions are automatically re-registered after OAuth or app reinstall, covering orders, products, customers, and app uninstalled topics.

How do I handle Shopify GDPR webhooks and data deletion requests?▼

Handle Shopify GDPR webhooks by implementing dedicated endpoints that acknowledge data deletion requests and perform required data lifecycle operations to ensure compliance with customer data removal and reporting regulations.

Why should I offload Shopify webhook processing to queues?▼

Offload Shopify webhook processing to queues to respond quickly with HTTP 200 while moving background work to async jobs, preventing delivery timeouts and enabling near-real-time system synchronization without blocking responses.

Can I use pub/sub for high-volume Shopify webhook delivery?▼

Use pub/sub for high-volume Shopify webhook delivery to distribute event-processing workloads, monitor delivery failures, and clean up stale subscriptions while maintaining reliable background system synchronization across services.
