You don't want to miss webhooks on Black Friday. Or any day, really.
Shopify fires webhooks on orders, refunds, inventory changes and customer events. During flash sales or campaign days they arrive in bursts — thousands at once. Miss one and your inventory is off or a refund stays open. WebhookFlow absorbs the flow and delivers at your system's pace.
Why Shopify webhooks demand robustness
Peaks during sales and campaigns
A quiet day brings ten orders an hour, Black Friday brings ten a minute. Plus all the associated inventory updates, refunds and confirmations. A server normally running smoothly can choke on this convergence — precisely when downtime hurts most.
Shopify gives up after 19 failed attempts
Shopify retries a failed webhook up to 19 times over 48 hours. Then your webhook subscription is automatically removed. If you keep missing after that you get no events at all — without any notice on your side.
HMAC validation required for app webhooks
Shopify signs every webhook with HMAC-SHA256. A misconfigured secret or proxy stripping headers leads to rejected events — often silently, and for a Shopify App that's an immediate integration problem.
What WebhookFlow specifically does for Shopify
Burst buffer for sale moments
If a thousand order events arrive during a flash sale, WebhookFlow accepts them all within milliseconds. We then feed your system at a rate it can handle. No overload, no lost orders.
Persistent retries beyond Shopify's 19 attempts
System unreachable for an hour during a sale? WebhookFlow holds events safely and retries for hours or days — not Shopify's strict limit.
HMAC validation at the edge
Configure your Shopify shared secret once in WebhookFlow. We validate every incoming request per the Shopify spec and reject mismatches before they touch your application.
Audit log per order event
See exactly which orders were forwarded, which retried, and what status your server returned. For a customer question or admin audit you have the full story — no Shopify support needed.
Frequently asked questions about Shopify webhooks
Does this work for Shopify Plus and Basic Shopify?
Yes. Shopify's webhook mechanism works identically across plan tiers. Plus customers have more event types available, but WebhookFlow accepts all of them without configuration differences.
Will I be notified if Shopify removes my webhook subscription?
Because WebhookFlow acts as the receiver and always returns 200, Shopify never approaches the 19-failed-attempts limit. Your subscription stays active, even during your downtime. For safety we also monitor delivery status from Shopify to WebhookFlow and alert on anomalies.
Can I replay webhook deliveries for specific orders?
Yes. In the WebhookFlow dashboard you see every received webhook with its payload and forwarding status. One click (or via API) replays it to your server — handy for a processing bug you've fixed.
How do I configure this as a Shopify App developer?
In your App settings or via the Shopify Admin API, set the webhook endpoint to the WebhookFlow URL. For multi-tenant apps you can generate a WebhookFlow endpoint per tenant, or use one central endpoint and route on the X-Shopify-Shop-Domain header.
