IN BRIEFEmmanuel Flossie’s 26 August checklist covers product IDs, attribute rules, supplemental sources, feed labels, remarketing IDs and conversion cart data after migration. Compare identifiers and source relationships with your previous setup before changing campaigns. This is a practical troubleshooting reference, not evidence that every account has a migration fault.
What changed
What this update covers
This article records the Paid Search update published in Paid Media News Week 38. The cited evidence is dated reference: 26 august 2026. It supports the specific scope described above; it does not establish a broader rollout, eligibility, performance outcome or commercial result beyond that evidence. The primary material for this record is Migration checklist.
How to assess it in your account
Start with the linked source and check whether the stated product, geography, account type and access conditions match your own setup. Treat an announcement, a limited beta, an account observation and a useful reference differently: each may be valuable, but they carry different levels of availability and certainty. If the change is relevant, document the current workflow before making a change so that later results have a meaningful baseline.
For “Merchant API migration: check the connections around your feed”, define the decision you need to make before treating it as an optimisation opportunity. That could be whether the capability is available, which customer journey it affects, what data is required, or how it interacts with an existing campaign, feed, creative process or measurement setup. Use a bounded test or review where access allows, and keep the source, date and account conditions with your notes.
Practical next step
Review the implementation details in the original material, then agree one success measure and one guardrail before acting. Compare the result with your existing setup rather than relying on a product label, a screenshot or a reported example alone. If access is selective or the source describes an observation, retain that limitation in any internal recommendation. The source media attached to this article was selected for the same update and is credited below; it illustrates the reported development but does not replace the underlying source documentation.
