Troubleshooting Product Feed Not Updating Correctly

When a product feed does not update as expected, the issue is usually related to product identifiers, feed structure, or feed settings. This guide summarizes common causes and fixes based on real cases.

1. Check Product Identifier Matching

Stock Sync updates products only when the identifier in the feed matches a product in your store. If only one product is updated or none are updated:

• Verify that the barcode, SKU, or product code used in Field Mapping matches the identifier used in your store.
• Ensure each row in the feed contains the correct identifier.
• If the store contains multiple products with the same SKU, enable Update duplicate products with same product identifier.

2. Verify Feed Structure (XML Files)

Some XML feeds use unique node names such as item_0, item_1, etc. This prevents proper row detection.

Fix: Apply a custom parser such as values(root) so Stock Sync can read all nodes. Contact support if the XML structure is unusual and cannot be adjusted from the interface.

3. Ensure Correct Feed Type (Add vs Update)

• Update Feed updates only existing products.
• Add Feed imports new products.

If new products do not appear, confirm that an Add Feed is used.

If the Add Feed shows "0 added" but no errors:

• Download the Changelog from the recent successful run to verify what was processed.
• Clear all filters and test import 2–3 products to ensure filters are not excluding items.
• Make sure no other feeds are currently running or queuing, as only one feed can process at a time.
• For Shopify, avoid option names containing the sequence " / " (space-slash-space), example: "Color / Finish". Shopify rejects these; use "Color/Finish" instead.

4. Check Stock Location Settings

If a product shows the wrong quantity or is not updated:

• Confirm that the Location selected in the feed matches the location used by the store.
• A mismatch prevents quantity updates even if the SKU matches.

5. Review Feed File Reading (Row Separator)

If the preview shows errors or missing rows, the file may not be read correctly.

• Adjust the row separator if supported.
• Some file formats require backend adjustment—contact support for assistance.

6. Verify Feed Automation and Scheduling

If updates work manually but not automatically:

• Open the feed detail page and click Set automation.
• Ensure the schedule is enabled (e.g., Daily at 1 pm).

7. Check for Duplicate Products Causing Conflicts

If a SKU does not update but appears correct:

• Search the SKU in your store.
• If both an Active and Draft product share the same identifier, Stock Sync may update only one.
• Enable “Update duplicate products” if needed.

8. Validate Feed Content

If some variants are not updating:

• Confirm the feed contains all variants.
• Check for missing or inconsistent identifier values.

If you continue experiencing issues, gather a sample SKU and contact support so the team can inspect sync logs and feed structure.

9. Additional Common Causes

• Store variant limit exceeded: When the store exceeds its variant limit, feeds may stop updating until the limit is increased.
• Filters excluding products: If vendor or other filters are applied, products not matching the filter (e.g., different vendor names) will not update.
• Feed file suddenly shrinking in size: A significantly smaller file (e.g., 10,741 rows down to 1,100) can cause many products to show as missing in feed.
• Payload too large / 499 errors: Large payload sizes may cause update failures; reducing the pagination or payload size resolves this.
• Unmapped fields remain unchanged: Only mapped fields update. Unmapped fields like Title or Description stay untouched.
