Supplemental product data sources allow you to apply your attribute rules and supplemental Content API feeds to multiple sub-accounts at the same time. When you set up a supplemental product data source, your product data will only be updated when the supplemental product data sources contain IDs that are in a primary product data source. The benefits of setting up supplemental product data sources include:
- Add or override custom labels for campaign management
- Add or override promotion IDs for retail promotions
- Override titles
- Exclude specific products (via the excluded destination [excluded_destination] attribute)
- Add missing Global Trade Item Number (GTIN)
- Add local inventory product data
Note: Only Content API supplemental product data sources can be created at the main account level. Supplemental product data sources are registered through rules, so supplemental product data sources only work together with multi-client account rules.
