2. The order never synced to Postflows
Postflows receives orders via Shopify webhooks in real time - there is no manual bulk sync. If an order doesn't appear, possible reasons:
The Shopify app is disconnected Go to Settings and check your store connection. If it shows as disconnected, reconnect. Orders placed during a disconnected period won't be retroactively synced.
The order is a draft order Postflows skips draft orders by design. Only orders that are confirmed/active in Shopify are processed.
The order was placed before Postflows was installed Postflows only receives new orders from the point of installation. Historical orders don't sync.
The Shopify app was uninstalled and reinstalled After reinstalling, Postflows resumes receiving new orders. Orders placed during the gap won't appear.
