OAuth errors appear there; for "stream missing" or visibility issues, open AI Instructions and filter by Shopify. Start at the **Shopify** source row in [**Data Sources**](https://platform.open.cx/data-sources). OAuth errors appear there; for "stream missing" or visibility issues, open AI Instructions and filter by **Shopify**. ## Common scenarios | Symptom | Likely cause | Fix | | ------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **OAuth popup errors or redirects to a blank page** | The **Allowed redirection URL** in your Shopify custom app doesn't match the Redirect URL shown in the connect dialog | Copy the exact Redirect URL from the OpenCX dashboard into your Shopify custom app settings, save, retry **Connect with Shopify**. | | **Products stream is empty but I enabled it** | The custom app doesn't have `read_products` scope — OAuth succeeds but Shopify returns zero rows | In your Shopify custom app, add `read_products` to the **Admin API access scopes**, save, re-authorize in OpenCX. | | **Articles sync but URLs aren't cited** | The Airbyte Shopify connector doesn't return the blog handle needed to build article URLs | Known limitation. The AI references articles by title when citing sources. For full URLs in citations, use the [Website crawler](/knowledge/sources/website/overview) against your public blog URL. | | **An unpublished product is showing in public replies** | `status` on the product is set to `active` but it's not actually visible on the storefront (inventory, channel visibility, etc.) | Change the product status in Shopify to `draft` or `archived` — the next sync flips visibility to `internal`. Or override per-item in AI Instructions. | | **Pages visibility looks wrong** | The page's `published_at` in Shopify controls visibility — publishing/unpublishing in Shopify admin may not have updated `published_at` as expected | Confirm `published_at` in Shopify. Publish the page, trigger a re-sync in OpenCX. | | **Multi-store request** | One connection per store today | Add a second OpenCX organization per store, or wait for multi-store scoping (contact support if blocked). | | **None of the above** | — | Contact support with the connection ID and a sample item URL. | *** ## Related Documentation Re-check scopes and redirect URL.
