About the Order API
Order requests behind click & collect and ship-from-store.
The Order API exposes endpoints for order requests: the orders a customer places in one channel and fulfils through a store.
Endpoints
The collect-side model
The parameters are named collectchainnum and collectstorenum rather than
chain and store, and that naming is the point: an order is queried by where
it will be collected, not where it was placed.
That is what makes the store-scoped GET the natural poll for a store’s own
fulfilment queue. A store asks “what do I need to pick today?” and gets exactly
its own unprocessed orders.
Retrieval endpoints return unprocessed orders. Advancing an order’s status
with PATCH is what removes it from that queue, so status updates are part of
the contract rather than bookkeeping.
