1. Overview
Due to Amazon's official requirement (as shown in the image below), the Sponsored Brands (SB) Ads API will be fully upgraded to V4 effective January 1, 2026. To align with this change, all V3 version SB ads on the Xnurta platform will be automatically migrated to V4 on the same date.
2. Impact of the Upgrade
The migration will be performed automatically with the following changes:
2.1 Campaign Migration
-
Existing V3 SB campaigns with the campaign state “enabled” or “paused” will be automatically duplicated to create new V4 campaigns (the new campaign name will automatically have the suffix "-migrated" added, as shown in the image below)
-
Records of the original V3 campaigns will remain accessible
2.2 Data & Status Changes
-
All V3 SB ads will be automatically archived
-
Historical performance data will remain in the V3 campaigns only – new V4 campaigns will not contain legacy data
2.3 Related Features
-
V3 SB campaigns linked to AI Managed Groups, Rule-based Automation, and Budget Groups will be automatically archived
-
Please review and adjust related settings accordingly
3. Recommendations
-
V3 campaigns are now clearly labeled in the system (as shown in the image below) – please make adjustments as needed
- In the campaign list, click ‘View All V3-SB Ads’ to filter and display all V3-SB campaigns (as shown below)
- Note: All newly created SB campaigns in the system are already V4
