Checkout / order integration with POS build on mobile web

I would like to create an Order or Checkout on the backend and then pay for it in a mobile application using Square Reader using build on web.

Is it possible to connect the payment execution using PoS build on web with the checkout or order API ?

Unfortunately this is a known limitation: currently the POS API (and POS Web API) do not support orders/itemization.

Thanks again …!! !!
