Automatically change prices based on inventory from CSV/XML in Shopify

We are looking for help to implement a system that changes prices in the Shopify store based on the inventory of products shared in a CSV/XML file by contractors.

Identification of products by product code (SKU).

There will be two conditions for changing prices: product with stock > 0 and product with stock <=0

An example of how this would work:

- The manufacturer provides a CSV/XML file at the link

- The program downloads and loads the file

- Checks the stock of each code, e.g. a product with code 0001 has a stock of 5 items, a product with code 0002 has a stock of 0 items.

- Changes prices in our Shopify-based store based on the same code (possibly with a prefix e.g. m0001, m0002) if the product stock is > 0 it changes the price to e.g. the price from the CSV/XML file - 5%, if stock = 0 it changes the price to e.g. 200 PLN

I don't know if this can't be done based on baselinker
