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 IDsMost 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.
