prestashop api code writer

We recently purchased a Prestashop 8.0 template suitable for our spare parts trading business. We also have an aspx plesk integration panel where we integrate and manage other marketplaces. You can use this panel to open bulk products, update prices, etc. We use it for intensive work. We will get support from our friend working in aspx. We want the friend we are looking for to include our Prestashop website by writing PHP compatible API codes to this aspx integration panel.
