Google Merchant Center now lets merchants upload product reviews through the API
Why it mattersE-commerce teams that had to hand-upload review feeds, or that gave up on the review surface because the manual step did not fit their release cadence, can now push reviews on the same schedule as their catalogue, and keep them fresh from the same automated pipeline.
Google updated the Merchant Center help document covering product review data sources to say that reviews can now be uploaded through the Merchant Center API. The archived 21 August version of the same page said API was not supported for product reviews. The change was spotted by Search Engine Roundtable on 18 September.
What the doc used to say and what it says now
The old page carried one line ruling out automation: "API isn't currently supported for product reviews data sources." The new page reads "Add product reviews using API." The rest of the document was rewritten in the same pass, so it now describes the Merchant Center Next interface path (Products and store, then Reviews, then Product reviews, then Manage product review sources) rather than the older Analytics menu path, and it names an explicit step in the onboarding flow where a Google account manager reviews an interest form and enables the account before the merchant can send reviews.
What this changes for a merchant
Product reviews are a separate feed from a merchant's product catalogue. Before this update the two feeds ran on different pipes: the catalogue could be pushed and refreshed through the Content API on whatever schedule the merchant chose, while reviews had to be uploaded by hand or through a scheduled data-source fetch of a static file. That mismatch is a common reason product review coverage lags behind the catalogue on Google Shopping surfaces, because a new SKU shows up with no reviews attached until the next manual upload catches up.
An API pipe closes that gap. Reviews from a checkout post-purchase email, from a third-party review platform, or from an in-store point-of-sale system can be sent to Merchant Center on the same schedule as the catalogue, and re-sent when a new review comes in or a review is removed. Google's own documentation describes the same workflow it already describes for catalogue data: fetch a token, POST a JSON payload against the data source, read back per-item status.
The onboarding gate has not gone away. The new page keeps the interest-form step, and the doc says a Google agent has to enable the account manually before uploads are accepted, so a merchant cannot self-serve into the feature purely through the API.
Where product reviews show up
Product reviews power the star ratings that appear next to a product listing in Google's shopping results, in Google Shopping tabs, and in the product-listing rich results that surface in classical search. They also feed the review passages that AI Mode and AI Overviews summarise when a shopping-intent query returns a specific product, which is why the API change matters for merchants tracking the AI-shopping surfaces as well as classical Shopping.
Google has not stated a date on the doc itself; the change window is 21 August to 18 September based on the Wayback Machine capture and the Search Engine Roundtable timestamp.
