Import and update products in Woocommerce from external api

Hello. we are creating a new woocommerce store. our supplier gave us a short documentation about and api they use that list the products in json format. every while a new product is added. so basically want we want is:

– Import the products with category mapping (with price +20-30%)
– Update stock
– Import new products when they arrive
– Have the option to disable price update on specific products.

Thank you
