QwikStone API

Build for the world's stone sellers.

One API for everything a seller does on QwikStone — stock and prices, orders and loading, pricing, ads, reports, Merchandising, payouts and Brand Shield. Sync an ERP, build a yard app, or sell your software to thousands of sellers.

PATCH /api/v1/listings/BG-20-07/inventory

# stock moved in your ERP → update QwikStone
curl -X PATCH http://seller.qwikstone.com/api/v1/listings/BG-20-07/inventory \
  -H "Authorization: Bearer qs_live_…" \
  -d '{"available_sqft": 1250, "price": 229}'

# 200 OK
{ "object": "listing", "sku": "BG-20-07",
  "inventory": { "available_sqft": 1250 }, … }

What you can build

Every part of Seller Hub has an API — with the same checks, so what your app does is exactly what a seller could do by hand.

Inventory & listings

Create listings by SKU, keep stock and prices in sync from Tally, SAP, Zoho or a spreadsheet.

Orders & loading

Read orders, confirm stock is ready and record truck arrival and loading. Webhooks tell you when anything changes.

Advertising

Create campaigns, manage keywords and bids, and pull performance reports — build bid tools and dashboards.

Reports & analytics

Sales, payments, listings, ads and buyer search terms — group them any way you like.

Pricing & payouts

The full price build-up per market, statements, invoices and payouts for accounting software.

Merchandising & Brand Shield

Apply stock for export by bid, accept offers, watch bids; manage brand protection.
