Script for automatic booking on the website of online stores

It is necessary to write a script for booking goods on the suppliers website.
Orders are received in MoiSklad.
Each order indicates the supplier, article and quantity of the goods.
At the time of receipt of the order, it is necessary to put the goods from the right supplier in the right quantity in the basket.
Every 3 hours it is necessary to place an order.
You also need a panel where all information on orders is displayed.
The panel should be two-way synchronized with My Warehouse.
