Google Ads API will remove ad sharing functionality starting October 15, 2025, with a full sunset planned for Q1 2026.
Advertisers will no longer be able to link a single ad across multiple ad groups. Each ad must now be uniquely created for each ad group, even if the content is identical. This aligns with Google’s shift toward asset-based ad formats, such as RSAs and Performance Max.
Why it matters:
- Streamlines ad management toward dynamic, asset-driven ads
- Ad history won’t carry over to the new ads
- Shared ads still live, will auto-convert in 2026, but custom migration is recommended

Advertisers using the Google Ads API should audit and update their setup to avoid disruptions and retain control over creative and performance.
