What problem does it solve?
It solves the recurring integration failures and data drift that happen when a seller connector updates VTEX marketplace SKUs, prices, and inventory without following the required changenotification, suggestions, and simulation flow.
Core Features & Use Cases
- Change Notification + SKU Suggestion Workflow: Correctly determine whether a SKU already exists (200) or must be suggested (404), then push new SKUs through the pending approval lifecycle.
- Seller-Scoped Price & Inventory Updates: Send price and inventory notifications to the proper VTEX notificator endpoints using the seller SKU identifier.
- Fulfillment Simulation Readiness: Implement a fast seller-side fulfillment simulation so the marketplace can fetch updated availability within the required timeout window.
- Rate-Limited Batch Sync with 429 Backoff: Throttle bulk notifications and implement exponential backoff to avoid blocking the integration during heavy updates.
Quick Start
Use the marketplace-catalog-sync skill to design your seller connector so it posts seller-scoped changenotifications, sends SKU suggestions to the api.vtex.com suggestions endpoint when needed, and serves a fulfillment simulation response fast enough for the marketplace to reflect updated price and stock.
