Set up supplemental product data sources for multi-client accounts

This feature is only available for retailers who have already opted in, and is temporarily unavailable for new retailers.

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.

Create new supplemental product data sources

Steps to create a new supplemental product data source:

1. In your Merchant Center account, select Settings in the left navigation menu.
2. Click Data sources.
3. On the Supplemental sources tab, select Add supplemental product data.

Note: You can add the supplemental data for multi-client account supplemental product data sources at the sub-account level through the Content API by using product.insert. This can be done by referring to the feedId of the supplemental product data source created in the parent account.
