Manual uploads and clunky file submissions are no longer the only way to get product reviews into Google Merchant Center. Google now lets merchants use its API to send review data straight into product listings. For retailers juggling thousands of SKUs or constantly updating reviews, this means less time spent on spreadsheets and more time keeping ratings up to date.
In August 2025, the Merchant API reached general availability, introducing real-time notifications, management of additional data sources, and support for both product and merchant reviews.
Alongside the API launch, Google has updated its documentation and reworked the Product Ratings workflow. The new instructions match the latest Merchant Center navigation: Products & store > Reviews > Product reviews > Manage product review sources. This streamlines review management and fits with Google’s push to modernize its e-commerce tools and language. For example, “feed submission” is now “data source submission.”
But automation doesn’t mean skipping the basics. Merchants still need to enroll in the Product Ratings program and have at least 50 product reviews before they can apply. The new process spells out that a Google agent will review each application before enabling product ratings in Merchant Center. This gatekeeping step hasn’t changed, so only qualified merchants get access to the API workflow.
Google’s documentation specifies that when using the rating attribute, the minimum rating (minRating) is mandatory. This ensures ratings are normalized and can be displayed across Google surfaces, impacting ranking signals for free listings.
For platforms and brands handling review data at scale, API support removes a major bottleneck. Teams no longer have to rely on scheduled fetches or manual uploads. Now, they can build automated systems that push review updates directly to Google. This is a big operational upgrade, especially for those already investing in automated reporting and analytics, as Abondance details in its review of the Merchant API’s evolution.
By bringing API-driven review management into Merchant Center, Google isn’t just catching up with e-commerce expectations-it’s setting a new standard for handling product ratings at scale. Merchants who move quickly will get a clear efficiency boost. Those who stick with manual uploads risk falling behind as automation becomes the new normal for product data.
