Steps
- On a key supplier’s Stock page click ⚙ API (next to Upload order sheet).
- Create a key there (it is shown once - copy it): it reads stock and your prices, and may also place orders.
- Your system calls GET …/key-suppliers/{supplier}/items - with updated_since it gets only what changed - and POST …/orders with the lines (sku, qty), the delivery location and your PO reference.
- Follow the orders with GET …/orders: status, dispatched and received quantities.
Good to know
- The prices are yours: the price agreed with you, else retail (price_basis) - never another dealer’s.
- A PO reference already used is refused, so a retry never orders twice.
- API keys need a package with API access; they are also listed in API Center → API keys.
