Uploading order details from a PDF customer order into Shopify without changing the product prices

We are in the final stages of building a solution where order details are extracted from a PDF sales order and uploaded into our client’s Shopify account.

We are using Make to control the workflow and PDFDataNet - pdfdatanet.com - to extract the data from the PDF. It seems that when we use the Make/Shopify API we must pass the product’s unit price which then updates the price set on the Shopify product file.

So the question is: Is there a way to tell the API to use the prices already set in the product file or alternatively tell the API not to update any existing, standing data?

Many thanks for any ideas or solutions anyone can suggest.
