Google has revised its Developer Policies, previously called the Google Ads API Policy, aimed at enhancing security for developer integrations.
Developers are advised to review these changes to ensure compliance. The Ads API Compliance team is currently reviewing existing integrations and will directly communicate necessary updates to affected developers.

The updates focus on eliminating reliance on programmatic proxies, urging integrations to connect directly via a dedicated Google Cloud project. This mitigates risks such as unauthorized access and performance bottlenecks, safeguarding data integrity.
