Amazon just announced the Inventory Management APIs for DSP, and I'm already thinking about how this would fit with Claude Cowork. 😃
Previously, managing Deals, Supplier Proposals, and Inventory Groups programmatically meant navigating a fragmented set of endpoints.
But now, they've consolidated everything under the v1 common model, which is far more consistent and maintainable.
As far as your Cowork/AI Assistant - Imagine telling it to "Pull all active deals across our DSP accounts, cross-reference their planning metrics against actual avails, and flag any deals where we're significantly under-delivering against forecast."
Great insights and a lot less work...
What's included right now in the release:
- Create, update, and read Deals, Inventory Groups, and Supplier Proposals
- Query deal planning metrics and deal avails
- Manage advertiser access to deals
- Full proposal lifecycle: create, revise, query history
- Supplier targeting, publisher, and ad product details
What's coming soon:
- Deal performance metrics
- Exchange listings
- Additional inventory group and advertiser access management
This follows the same pattern we saw with the Sponsored Ads Unified Endpionts, and that was a massive win. Seeing DSP get the same treatment is exciting.
