Amazon Custom Orders

We sell a lot of ‘custom’ orders on Amazon. Unfortunately, at the moment, Veeqo only brings in the title of the listing when we print the orders, not the customised data for what the customer has actually wanted.
I have spoken to Veeqo and sadly there is no immediate plan to pull this data in as part of the invoice/picking slip.
Therefore, I was wondering if this data could be brought in through an API of some sort.
Has anyone else tried to get this information from Amazon into Veeqo?
Thanks!
