API Landscape
Google provides two APIs for Merchant Center. The Merchant API (v1) is the current standard. The Content API for Shopping (v2.1) is the legacy API, sunsetting August 18, 2026.
| Aspect | Merchant API (v1) | Content API for Shopping (v2.1) |
|---|---|---|
| Base URL | https://merchantapi.googleapis.com |
https://shoppingcontent.googleapis.com |
| Transport | gRPC (default) + REST | REST only |
| Status | Active, GA | Sunset August 18, 2026 |
| Design | Modular sub-APIs | Monolithic |
| Batching | Async / HTTP batching | customBatch methods |
Always prefer the Merchant API for new integrations. Only use Content API if maintaining legacy code or if a feature hasn't migrated yet.
