Item type

Hi,

We are using OPENPOS on our site. It has a feature where you can apply a discount to an order within the POS.
We need to pull this into the report or the orders do not tally up.
We have spoken to the developers and they say –

get item type = fee to get that info

check this guide?

Unfortunately this makes no sense to us and we require some assistance on how to do this, happy to pay for support if required.
Many thanks in advance
