The API lets you manage product feed data through three API surfaces:
- Feeds creates product feeds and retrieves feed metadata.
- Products retrieves products for a feed and upserts partial product changes.
- Promotions retrieves promotions for a feed and upserts partial promotion changes.
Use these APIs together when you want to create a feed, retrieve current data, and upsert product and promotion changes through API-based delivery instead of file upload.
REST endpoints
All API endpoints use the same request headers and response
headers. The Feeds, Products, and Promotions subtabs define the endpoint-
