Keep ERP, storefronts, and tools in tandem

Tandem is the partner-facing catalog layer. Pull published products, contract prices, and order events through documented APIs — without manual file drops.

Customer catalog API

Trade partners authenticate with Sanctum tokens. List and search published products at their price list prices, fetch categories, and subscribe to webhooks. Use updated_since for incremental nightly syncs between poll intervals.

GET /api/v1/products?updated_since=2026-06-01T00:00:00Z

Webhooks

Signed payloads for product lifecycle and fulfilment events:

  • product.published
  • product.updated
  • product.discontinued
  • shipment.created

Supplier image sync API

For desktop sync tools and DAM workflows: staff authenticate, list images (including empty SKU folders), upload and replace assets by SKU, and sync incrementally with deletion tombstones.
