Google Killed the Content API for Shopping on September 1 — Is Your Product Feed Still Working?

What Actually Changed on September 1

For years, stores pushed product data into Google Merchant Center through the Content API for Shopping. Google replaced it with the Merchant API and set September 1, 2026 as the operational deadline. From that date, requests to the old endpoint can start failing. Google isn't flipping a single switch that breaks everything at once — which is precisely the problem. A feed can degrade gradually, with products expiring out of Shopping results one batch at a time, while your website looks completely normal.

Why This Is a Silent Failure

A broken product feed doesn't throw an error your customers see. Your site loads. Checkout works. What disappears is your presence in Google Shopping, Shopping ads, and increasingly the product data Google uses to surface items in AI Overviews and AI Mode. The first sign most store owners notice is a traffic drop they can't explain — often weeks later, once the last cached product listing has expired.

Who Is Actually at Risk

If you use a major platform's native Google integration, the platform has almost certainly migrated on your behalf. The risk sits with everything else:

• — Custom-built feed integrations written against the Content API
• — Older third-party feed apps or middleware that stopped receiving updates
• — Agency-built connections from a previous developer nobody currently maintains
• — Multi-store setups where one integration was migrated and another wasn't

The Five-Minute Check

Open Google Merchant Center and look at three things: the last successful feed update timestamp, the count of active versus disapproved or expired products, and the Diagnostics tab for API errors. If the last successful update predates September 1, or the active product count has started sliding, your integration is talking to a dead endpoint. That's the whole diagnosis. The fix is migrating to the Merchant API, which is straightforward if you know your integration exists — and impossible if you've forgotten it does.

Why the Timing Is Unforgiving

Holiday shopping is weeks away. Stores are already pushing early promotions, and Google Shopping visibility matters more between October and December than at any other point in the year. A feed that quietly died on September 1 and gets noticed in November has cost a store its most valuable weeks of product visibility. Check it now, while the fix is a migration rather than a post-mortem.

Feed Infrastructure Built to Last — With Devrex Digital

Devrex Digital builds custom stores with product feed integrations we maintain against current Google APIs — so a deprecation like this one becomes a scheduled migration, not a surprise. If you're not certain how your products reach Google, or who built the connection, we can audit the integration and confirm it's on the Merchant API before the holiday window opens.
