A field name that is not in the writable set is no longer dropped silently — the request is rejected with 400 INVALID_PARAMS and the error text lists the writable names. Read-only fields that appear in product-row responses (priceAccount, ownerId, storeId and others) are still accepted and ignored, so an object read via GET can be sent back as is.

A row whose fields are unchanged keeps its id. A modified row comes back with a new id even when the previous identifier is sent in the body. To edit a row and keep its id, use PATCH /v1/quotes/:id/products/:rowId.

Set quote products

PUT /v1/quotes/:id/products

Known specifics

Full replacement: PUT replaces the entire product list. To add a row — first get the current ones (GET), add the new one to the array, and send everything (PUT). Fetch the whole list: without limit, GET returns only the first page, so pass limit=5000 or page through with offset until meta.hasMore is false. Sending back an incomplete list erases everything it omits.
