Google Shopping API Migration: a Looming Deadline for Advertisers

Migration Deadline Approaches

Google’s transition from the legacy Content API for Shopping to the new Merchant API is not just another update; it’s a hard cutoff that threatens ad delivery for unprepared advertisers. The fully deprecated Content API will cease operation after August 18, 2026, leaving those who fail to migrate at risk of disrupted product feeds essential for Shopping and Performance Max campaigns. Google first announced this shift in mid-2024, but the urgency has intensified as deadlines draw near.

Implications for Ad Campaigns

Advertisers relying on the Content API must complete their migration by February 28, 2026, if they participated in the beta testing of the Merchant API. The risk here is substantial; if product feed syncing is interrupted, campaigns will stop serving ads. This is particularly critical for those that depend on feed labels for segmentation and bidding strategies.

Additionally, feed labels do not automatically migrate. This requires manual reconfiguration in both Google Ads and Merchant Center, a task many may overlook. Ignoring these requirements will result in outdated product data, leading to poor campaign performance or outright disapproval of ads.

Steps to Ensure a Smooth Transition

Advertisers should act immediately to verify their API usage. In the Merchant Center Next, navigate to Settings > Data sources and check the ‘Source’ column for any listings marked as “Content API.” If present, take action to migrate to the Merchant API. Google recommends early migration, including a thorough review of feed labels and ensuring that feeds are reconnected properly.

New Features in the Merchant API

The Merchant API claims to offer enhanced automation and scalability for product data management, addressing many limitations present in the legacy system. While this might streamline operations, one must consider the underlying motive: Google’s ongoing push to consolidate control over advertising data. As history has shown, this often leads to increased costs for advertisers.

This shift aligns with previous deprecations in Google’s services, where simplification often translates to a tighter grip on revenue streams. Those transitioning must remain vigilant against potential hidden costs and operational risks as the platform modernizes.

What Lies Ahead

Expect an uptick in enforcement as the cutoff dates approach. Advertisers who delay migration risk not only revenue loss but also operational chaos as critical components of their campaigns come to a halt. This isn’t just a technical adjustment; it’s a significant business risk.

Over the next six to twelve months, anticipate increased communication from Google regarding migration progress and potential consequences for non-compliance. Prepare for a tightening of policies and perhaps even additional requirements as the deadline looms.
