Webhooks
Notifications Shopify sends to another system when something happens, such as an order.
WHY IT MATTERS
Why it matters for a Shopify store.
Webhooks are messages Shopify sends to another system when something happens — an order is created, a product updated, a customer signs up.
They keep ERPs, warehouses, CRMs and custom apps in sync in near real time, without constant polling — the basis of reliable integrations.
HOW CREATIVE LABS HANDLES IT
What we do about it on every project.
01
Subscribe to what's needed
Only the topics the integration actually uses.
02
Verify every request
Webhook signatures are checked before data is trusted.
03
Handle retries and duplicates
Receivers are idempotent and failures are logged and replayed.
EXAMPLE
A typical example.
A brand's ERP needs every paid order within minutes.
An orders/paid webhook sends each order to a small integration service, which checks the signature, transforms the data and posts it to the ERP, logging any failures for retry.
COMMON MISTAKES
What usually goes wrong.
Skipping signature checks
Unverified webhooks can be spoofed.
Assuming exactly-once delivery
Webhooks can arrive twice or out of order.
No monitoring
Silent failures leave systems out of sync.
WEBHOOKS
2 questions
Are Shopify webhooks guaranteed?
Shopify retries failed deliveries, but receivers should still handle duplicates and reconcile periodically.
Webhooks or Shopify Flow?
Flow suits automations inside Shopify and connected apps; webhooks suit custom integrations with external systems.
