PHP API on Prestashop

Hello everybody
 
I have a website with Prestashop, our supplier provides through an API all data available so that we can read this data in our shop. (Pictures of products, prices, stock, description ect.)
I had a lot of contact with Prestashop, but I still managed to connect to this API using a tool. This means that the connection to this server works so far.
I have to integrate the whole thing in Prestashop now.
The API is currently creating a CSV file, which I manually import into Prestashop.
The whole thing must be done automatically, however, that the products are automatically added when a product is present, then an update must be made (if there is a change in the same product).
 
thank you very much
