Shopify webhook events are a core integration mechanism for any app, middleware, or storefront that needs real-time updates from a Shopify store. This guide explains what Shopify webhook events are, how they work in 2025, how to register and verify them, best practices for reliability and security, real-world use cases, troubleshooting tips, and code examples to help you implement robust webhook handling in production.

What are Shopify webhook events?

Webhooks are HTTP callbacks that allow Shopify to send event-driven messages to your application when something happens in a store—like an order being created, a product being updated, or an app being uninstalled. In Shopify terminology these are known as webhook events or webhook topics. Rather than polling Shopify APIs, your app receives push notifications so you can react immediately.

For a formal definition of webhooks and how they’re widely used, see the Webhook entry on Wikipedia. For Shopify-specific documentation and the current list of topics, always consult the official Shopify developer documentation: Shopify Webhooks — Shopify Dev.

Why Shopify webhook events matter in 2025

Real-time automation: Sync inventory, trigger fulfillment, or update CRM systems immediately when store data changes.
Cost-efficiency: Avoid repeated API polling and reduce rate-limit pressure on both your app and Shopify.
Reliability: Modern webhook delivery mechanisms (including robust retry policies and delivery logs) mean you can build reliable integrations.
Security improvements: HMAC verification and HTTPS requirements secure your endpoints against replay and tampering.
Better developer tooling: GraphQL webhook subscriptions and CLI tooling make registering and testing webhooks easier.

Common Shopify webhook topics

Shopify provides many webhook topics. Examples of frequently used topics include:

orders/create — triggered when a new order is created.
orders/paid — fired when an order is marked as paid.
orders/updated — when order details change.
products/create and products/update — product catalog changes.
customers/create and customers/update — customer account changes.
fulfillments/create and fulfillments/update — fulfillment lifecycle events.
app/uninstalled — when a merchant uninstalls your app (important to clean up subscriptions).

See Shopify’s detailed topic list in the official docs for the full and up-to-date list: Available webhook topics — Shopify Dev.

How Shopify delivers webhook events

When an event occurs, Shopify sends an HTTPS POST request to the webhook URL you registered. The request includes:

Headers such as X-Shopify-Topic, X-Shopify-Shop-Domain, X-Shopify-Hmac-Sha256, X-Shopify-Webhook-Id.
A JSON payload in the request body that describes the event.

Important delivery behavior:

Shopify retries deliveries on failure with exponential backoff; monitor delivery logs in the Shopify admin for details.
Delivery timeouts matter—your endpoint should acknowledge requests quickly (respond 200) and perform heavy processing asynchronously.
Webhooks are delivered over TLS; Shopify requires valid HTTPS endpoints.

Registering webhook subscriptions

There are two primary ways to register webhook subscriptions:

Admin API (REST) — Create webhook subscriptions by POSTing to the REST endpoint (e.g., /admin/api/2025-01/webhooks.json). This works for many integrations and legacy flows.
GraphQL Admin API — Use the webhookSubscriptionCreate mutation to create subscriptions and manage them via GraphQL. This is now the recommended approach for many apps and is ideal for typed schemas and GraphQL-first stacks.

Example (conceptual) GraphQL mutation for creating a webhook subscription:

mutation {
  webhookSubscriptionCreate(topic: ORDERS_CREATE, webhookSubscription: {callbackUrl: "https://yourapp.example/webhooks/orders_create", format: JSON}) {
    userErrors { field message }
    webhookSubscription { id }
  }
}

When developing, you can also configure webhooks through the Shopify admin UI for convenience. For programmatic control in production, use the Admin APIs. Refer to Shopify’s registration docs: Configure webhooks — Shopify Dev.

Verifying webhook authenticity (HMAC verification)

Security is critical. Shopify signs webhook bodies with an HMAC using your app’s shared secret and sends the signature in the X-Shopify-Hmac-Sha256 header. The right verification method prevents spoofed requests and replay attacks.

Node.js (Express) verification example:

const crypto = require('crypto');

function verifyShopifyWebhook(rawBody, hmacHeader, secret) {
  const digest = crypto
    .createHmac('sha256', secret)
    .update(rawBody, 'utf8')
    .digest('base64');

  // Use timingSafeEqual to prevent timing attacks
  return crypto.timingSafeEqual(Buffer.from(digest), Buffer.from(hmacHeader));
}

Key points when verifying:

Use the raw request body exactly as received for HMAC calculation; JSON-parsing and re-stringifying can change whitespace and break verification.
Compare digests using a timing-safe comparison to prevent timing attacks.
Reject requests that fail verification with a 401 or 403 status code and log suspicious activity.

Best practices for reliable webhook processing

To build a resilient system that processes Shopify webhook events correctly, follow these best practices:

Respond quickly: Acknowledge with HTTP 200 as soon as possible. Defer long running tasks to background jobs or message queues.
Idempotency: Shopify may deliver the same event more than once. Use the X-Shopify-Webhook-Id header or compute a unique fingerprint from the payload to deduplicate.
Store event metadata: Persist webhook id, topic, and timestamp to help with auditing and troubleshooting.
Retry handling: Build idempotent consumers and exponential backoff on your side for operations that call third-party services.
Logging and monitoring: Log events, outcomes, and errors; set up alerts for repeated failures on specific topics or shops.
Secure endpoints: Enforce HTTPS, verify HMAC signatures, restrict accepted HTTP methods (POST only), and validate payload schema.
Rate limiting and batching: If you need to call external APIs for each webhook, batch updates or use rate-limited workers to avoid downstream throttling.

Design patterns for webhook-driven architectures

Below are common patterns that improve maintainability and scalability:

1. Queue + Worker Pattern

Accept webhooks quickly, push the payload to a durable queue (e.g., RabbitMQ, Amazon SQS, Google Pub/Sub), and process asynchronously with worker processes. This isolates temporary downstream failures and enables retries.

2. Event Store / Audit Log

Persist raw webhook payloads and metadata in a storage layer for auditing. This makes it easier to replay events and debug merchant issues.

3. Microservice Segmentation

Route different topics to domain-specific microservices. For example, orders topics go to an order-processing service, product topics to a catalog service, and customers to CRM sync services.

4. Idempotent Consumers

Ensure operations are idempotent. For example, update database records using upsert semantics or compare timestamps before applying changes.

Handling specific scenarios and examples

Orders created — common workflow

Receive orders/create webhook and verify HMAC.
Persist the webhook id and payload in an event store.
Enqueue a job to process payment validation, fraud checks, inventory reservation, and fulfillment orchestration.
Return 200 immediately on enqueue success; if enqueue fails, return 500 so Shopify will retry.

Product updates — inventory sync example

When a product or inventory item changes, update your internal catalog and, if needed, recalc pricing, promotions, and search indices. For multi-warehouse setups, reconcile by checking the variant IDs and inventory_item_id values from the webhook payload.

App uninstalled — cleanup tasks

When you receive an app/uninstalled webhook, revoke access tokens, stop background jobs for that shop, and optionally archive merchant data in accordance with privacy policies and applicable law.

Security checklist for Shopify webhook events

Always require HTTPS (TLS 1.2+).
Verify X-Shopify-Hmac-Sha256 on every request.
Store secrets securely (use a secret manager or encrypted environment variables).
Limit accepted origins if applicable and block suspicious IPs with WAF rules.
Rate-limit on your endpoint to prevent resource exhaustion from malformed or malicious requests.
Audit and rotate keys periodically; handle secret rotation gracefully by supporting dual-secret verification during a transition window.

Testing and development workflows

Shopify provides several tools and approaches to test webhook integrations:

Shopify Admin: You can manually create test webhooks from the store admin and send test payloads.
Shopify CLI: When developing apps, use the Shopify CLI to serve and forward webhooks to your local environment.
ngrok or localtunnel: Expose your local server to the internet to receive webhooks from Shopify during development.
Unit tests: Mock webhook payloads and HMAC headers to test verification and business logic.

Monitoring and troubleshooting webhooks

Shopify provides delivery logs for webhook transmissions in the admin where you can review response codes and replay deliveries. Key troubleshooting steps:

Check delivery logs in Shopify admin to see response codes and retry history.
Verify that your endpoint responds quickly and returns 200 for successfully queued requests.
Confirm correct HMAC verification and that the raw body is used for digest calculation.
Inspect application logs for exceptions or JSON parsing errors.
If payloads are large, ensure your server accepts sufficiently large request bodies and that any firewall or proxy isn’t truncating content.

Scaling webhook handling for high volume stores

High-volume merchants can generate hundreds or thousands of webhook events per minute. To scale:

Use horizontal scaling for worker processes processing queued jobs.
Partition queues by topic or shop to spread load across workers and avoid hot partitions.
Use backpressure and circuit breakers when downstream services are degraded.
Aggregate events where possible (e.g., consolidate frequent product updates into scheduled sync jobs if real-time isn’t required).

Legal and privacy considerations

When you receive merchant or customer data via webhooks, make sure to comply with applicable laws (e.g., GDPR, CCPA) and Shopify’s partner terms. Store and delete data as required by agreements and local regulations. When an app is uninstalled, act on app/uninstalled to purge or anonymize data as necessary.

Real-world integrations and use cases

Here are practical integrations you can build with Shopify webhook events:

Fulfillment automation: Auto-send orders to fulfillment partners or print shipping labels when a fulfillment is created.
ERP sync: Update inventory, accounting, and order records in ERP systems in real time.
Fraud detection: Run newly created orders through fraud scoring and take automated actions (hold, flag, cancel).
Analytics & BI: Stream events into analytics pipelines (via Kafka, Kinesis) for near-real-time dashboards.
CRM integration: Sync customer creation and order history to CRM systems for marketing automation.

Shopify webhooks vs Polling: when to use each

Use webhooks for event-driven updates and near-real-time needs. Polling still has valid use cases—such as catching missed events, large bulk syncs, or obtaining full resource lists for reconciliation. Design systems to use webhooks as the primary signal and reconciliation jobs that poll at off-peak times for consistency.

Example end-to-end flow

Merchant installs your app and you create webhook subscriptions using GraphQL or REST.
Store performs an action (e.g., new order created).
Shopify sends a POST request to your webhook endpoint; your server verifies HMAC and enqueues the job.
Worker processes job, updates internal systems, notifies third-party services, and logs completion.
If processing succeeds, nothing else is required; if processing fails, implement retry and alerting.

Troubleshooting checklist

Confirm webhook registration and callback URL are correct.
Check delivery status in Shopify admin for error codes and timestamps.
Ensure your app’s secret matches the secret used for HMAC verification.
Examine server logs for JSON parsing errors, timeouts, or 500-level errors.
Test with a known working payload and verify your endpoint returns 200.
