# Product interface use scenario guidance

This document describes the use of the SPU interface.

# Scenario 1 Add / Modify Products

When you synchronize a product, an audit will be triggered, and you need to access the event callback to wait for the results.

# Scenario 2 Up / Down Items

Only items with online data can be placed on the shelves.

# Scenario 3 Withdraw an Audit

If the item is under review and needs to be updated, you need to withdraw the item review and update the item.

If a violation is found, the goods will be removed from the system.
