What’s new in CrossUp for integrators, dated. A breaking change is announced before it ships; see Versioning.
Agencies
Agency access. An agency integrates its clients’ stores with the same recipe in each one and a separate key per store. See Keys and security.
Admin
Multiple storefront keys per merchant. From the admin you create, rotate and revoke keys without downtime: the new one runs alongside the old one until you retire it.
API
Storefront signals. New operation POST /v1/connections/{connection_id}/storefront-signals: up to 50 signals per batch, tied to the recommendation’s decision_id and answered one by one.
Agents
CrossUp for coding agents. The CrossUp MCP, llms.txt and the integrator skill let Claude, Cursor or Codex integrate for you. Includes the crossup CLI for diagnostics.
API
Open API. The platform-api v1 contract is published as OpenAPI, with a generated reference and a playground on every operation. See The API.
Connectors
Custom connector. VTEX and your own stores, headless or custom-built, send their catalog and orders through the connector protocol. Today the CrossUp team builds it with you. See What a connector is.
Storefront SDK
@crossup/storefront is born. The SDK to request recommendations and report signals from your store, with no dependencies and without breaking the page. Published on npm.
