Legacy Sponsored Brand ads metrics
From today, April 30, 2026, some older Amazon Sponsored Brand campaigns may no longer show spend or performance metrics in Publisher Champ.
This affects Sponsored Brand campaigns created before August 2023.
This is due to a decision made by Amazon. It is outside of Publisher Champ's control.
You do not need to recreate your legacy campaigns to try this Publisher Champ solution.
You can keep your current legacy Sponsored Brand campaigns and synchronize their historical Amazon Ads data again by following our Historical Amazon Ads guide.
This manual sync needs to be performed once per day to fill the gaps for legacy Sponsored Brand campaign spend. Because Amazon no longer provides these legacy metrics through the latest API, Publisher Champ cannot automatically pull this missing data unless this manual process is followed.
Amazon has confirmed that older Sponsored Brand campaigns are now treated as legacy campaigns. These campaigns can still run and spend money, but Amazon no longer supports new advertiser features or measurement metrics for them in the latest Amazon Ads APIs.
Because Publisher Champ receives Amazon Ads data through Amazon's reporting APIs, we can only show the data that Amazon makes available. If Amazon no longer sends spend or performance data for a legacy campaign, Publisher Champ cannot display that data.
This does not mean the data is missing inside Publisher Champ. It means Amazon is no longer providing the reporting data for those older campaigns through the current API.
Amazon recommends recreating legacy Sponsored Brand campaigns as new ad group based campaigns.
You can do this by cloning the existing campaign in the Amazon Ads console. After the cloned campaign is created as a current campaign type, Amazon should support the newer reporting and measurement features for that campaign.
Which campaigns are affected?
This applies to legacy Sponsored Brand campaigns, especially campaigns created before August 2023.
Amazon completed this change in two stages:
- US marketplace: May 22, 2023
- All other supported marketplaces: August 10, 2023
Amazon has also said that legacy Sponsored Brand campaigns are in "Lights On" mode. In simple terms, this means the campaigns may still deliver ads, but they do not receive the same updates, features, and reporting support as newer campaign types.
Why spend may not appear in Publisher Champ
Publisher Champ imports Amazon Ads performance data from Amazon's latest reporting APIs.
For legacy Sponsored Brand campaigns, Amazon no longer provides the same reporting data in those APIs. This can include spend and other performance metrics.
As a result, these campaigns may appear to have no spend in Publisher Champ, even if they are still active in Amazon Ads.
What should I do?
Amazon's recommendation is to migrate these campaigns by cloning them in the Amazon Ads console.
If you have legacy Sponsored Brand campaigns, we recommend checking them in your Amazon Ads account and recreating them as new ad group based campaigns where possible.
If you are not familiar with the Amazon Ads console, Amazon recommends contacting your Amazon representative or getting assistance with the migration.
Why migration matters
Amazon has also warned that keeping legacy campaigns can cause other issues beyond reporting.
For example, in June 2024, Amazon issued an alert that some legacy Sponsored Brand version 3 campaigns created before October 2022 had gone missing in the advertising console after being rejected during creative moderation.
Amazon strongly recommended recreating all version 3 Sponsored Brand campaigns as new version 4 campaigns to avoid similar issues.
In short: if an older Sponsored Brand campaign is no longer reporting spend in Publisher Champ, the expected fix is to clone or recreate the campaign in Amazon Ads so it becomes a current campaign type supported by Amazon's latest systems.
