# Shopify order and customer data is stale or missing recent orders

> Shopify data stale or missing recent orders? The app's API permissions were likely revoked or an OAuth flow was left incomplete. Re-authorize and test the connection — Upstack backfills up to 7 days.

**Quick check:** Go to **Settings → Sources** in your Upstack dashboard. Each connected source shows a **Last synced** timestamp and a health indicator — click into any red or stale source to see the specific error.

**Likely cause:** The Shopify app's API permissions were revoked or the app was uninstalled and reinstalled without completing the full OAuth flow. Shopify stops sending webhooks and blocks API access when permissions are incomplete.

**Fix:**

1. In your Shopify admin, go to **Settings → Apps and sales channels**.
2. Find **Upstack Data** in the list. If it shows a warning icon or says "Access limited," the permissions need to be re-granted.
3. Click **Upstack Data** → **App settings** → look for a **Re-authorize** or **Update permissions** prompt.
4. Complete the OAuth flow — ensure you approve all requested scopes (orders, customers, products, checkouts).
5. After re-authorizing, return to Upstack → **Settings → Sources → Shopify** and click **Test Connection**. The status should change to green.
6. Upstack will automatically backfill missed data for the period it was disconnected (up to 7 days). For longer gaps, contact support to trigger a full historical sync.
