Request for ZOHO INVENTORY integration API with our FULFILLMENT LOGISTICS

Hello, I need to have support as we need it ntegration between zoho and our logistics center to make sure that the correct availability of each P / N product we have in our fulfillment Logistic Centre can be seen on zoho, but IT support of Logistic Centre has problems whit API of this type:

which endpoints we need to use for:

orders (purchase orders, transfer orders, sales orders)
- invoices (there's 33 endpoints)

To sum up, our goal is to have the stock availability of Logistic Centre Warehouse exactly same in Zoho, means that Zoho has to read the stock with have in Logistic Centre as this is the only one real.
Then logistic Centre has to read the orders and invoices we add on Zoho as well as purchase orders towards suppliers.

I would be happy if someone could help me.
