We're excited to announce new Search Engine Marketing (SEM) APIs to help sellers and solution providers identify issues affecting campaign items and retrieve optimization recommendations for active campaigns. These APIs provide greater visibility into item-level diagnostics and campaign performance opportunities, enabling partners to build remediation and optimization workflows directly into their applications.

Added: Campaign recommendations API
New API for retrieving campaign optimization recommendations:
- Search campaign recommendations to retrieve budget and bidding strategy recommendations, along with projected performance impact metrics
Why it matters
