Trying to send a list of things data through Zapier

Trying to create an invoice with a list of items.

Invoice is a data type with some feilds within which items is a list.

When im using Zapier to send it to an invoice software it only sends through the unique IDs within this list.

Each item has a cost quantity sub total total and total with GST etc.

How do i get around this? Do I need to change my data structure or is there another way to send it to zapier from bubble that Im missing?
