Catalog management and listing automation for Walmart Marketplace sellers, built for trading cards and collectibles.
Collectibles categories are mapped into Walmart-facing item taxonomy and listing workflows.
The integration covers item management, inventory and price sync, orders, and return visibility.
Inventory, pricing, and item updates push on a schedule as product state changes.
Purpose-built for Walmart Marketplace sellers moving real card volume.
Create and maintain Walmart Marketplace items through the Items and Feeds APIs. Automated category selection and attribute mapping built for trading cards and collectibles.
Submit large item batches with validation applied before the feed is sent. Condition, pricing, imagery, and card attributes are checked so feeds are not rejected on preventable errors.
Scheduled inventory and price updates keep Walmart current as stock moves. Quantity reconciliation guards against overselling single-quantity graded cards.
Orders import automatically for acknowledgement, shipment confirmation with tracking, and cancellation handling — all from the same workspace as the rest of the catalog.
Return cases import alongside orders so sellers track resolution and restock in one place, without a separate portal.
Cards are matched to verified catalog records before listing, so set, parallel, serial number, and grade are correct at submission rather than corrected afterward.
From card ingestion to a live, synchronized listing.
Cards are added by photo, spreadsheet, or bulk upload. AI recognition reads the card and cert label, then matches it to a verified catalog record.
Catalog attributes are mapped to Walmart's item taxonomy. Condition grades translate to Walmart condition values and required fields are validated before submission.
Validated items are submitted as a Walmart feed. Feed status is polled to completion so per-item errors surface against the card that caused them.
Inventory, pricing, and item updates push on a schedule. Orders and return cases flow back for fulfillment and resolution.
