Subscribe to catalog changes
- You can now subscribe a webhook to a catalog and receive its product changes — created, updated, and archived — as batched, signed events, so your systems stay current without polling. See Catalog Subscriptions.
- Delivery is at-least-once with a stable
event_idfor deduplication, retries on a widening schedule, and automatic pausing of an endpoint that stays unreachable.
API documentation served from your environment
- API documentation moved to the
/api/nexus/api-docs/route in your environment, with API Reference, API Keys, and Service Accounts in one place. - The API reference is now generated from the API itself, so it always matches the version running in your environment.
This page is updated as the API and its documentation evolve.
