Connect API

You need to create a database or csv file, on the one hand connect the store by api https://www.sima-land.ru/api/v3/help/ and on the second by api the personal account valdberis. So that prices and balances in the database are automatically updated 1 time in a given period.
In the database in one column the articles of the store https://www.sima-land.ru/api/v3/help/, in the second articles for Valdberis (articles are entered manually by me) in the third balances, in the fourth price
It is necessary to make a function so that I can adjust the markup to create a static page or something else see the example in the photo
If there is an order on Valdberis that this order goes to the cart on the https://www.sima-land.ru/api/v3/help/ website (you need a function so that you can insert a login and password for your personal account)
It is necessary that it is possible to connect simultaneously different cabinets of Valdberis and https://www.sima-land.ru/
