Extend the Connect / Carrot Ads API with clear contracts, robust event: handling and dead-letter recovery, integration tests, and self-serve documentation that makes partner onboarding faster and more reliable.
Build the retailer control surface: relevance and quality-score inputs, reserve pricing, ad-load controls, and the trade-off signals retailers use to tune performance on their own sites.
Strengthen reporting and data integrity across partner systems: including attribution, catalog and product-ID mapping, reconciliation, and automated health checks that keep partner data trustworthy.
Raise reliability by helping define and meet partner SLAs, improving: observability, reducing incident frequency and time to recovery, and contributing to a unified partner-health monitoring layer.
