Connect a supplier or dropshipping app

How a supplier lists its products in a merchant's store, keeps stock right, and receives the orders.

1. Connect the store with an install link asking for products.read,products.write,categories.read,orders.read,orders.write,shipping.write,webhooks. Save api_key and webhook_secret per store — one supplier account usually serves many stores.
2. Import products with Create a product. Put your own code in sku (and in each variant's sku).
3. Keep stock in sync with Update stock by SKU whenever your warehouse changes.
4. Set delivery prices with Update shipping zones so the store charges what you charge.
5. Receive orders on your webhook (order.created), verify the signature, fetch the order with Get an order, and keep the lines whose sku is yours.
6. Report progress with Update order status (processing → shipped → delivered) and Add an order note for tracking numbers.
