After Sellers request to create an Inbound Order, WFS may return error responses with error codes. Type of errors:

• SKUs not in WFS catalog: Sellers need to make sure all SKUs have already been converted and added to the WFS catalog
• Missing required information;
• Invalid Product ID (incorrect number of digits);
• Duplicated Inbound Order ID: Inbound Order ID has already been used before
• Duplicated Product IDs
  Most of these errors can be prevented with a robust API integration that does not allow the mistakes to be made. Seller should update the request based on the error message and re-submit the request.
  Please note, once the Inbound Order is created successfully after the re-submission, historical errors under the same Inbound Order ID will be removed and no longer accessible.
