Sync Amazon Products price with own Mercado Libre Store Price

I have a Mexico Mercado Libre store which i sell things that i buy from amazon US, i would like that if a product changes price in amazon automatically it also changes the price in Mercado libre. As well as the stock, if it goes out of stock in amazon US it changes to out of stock in Mercado Libre.
Also i need the same thing but with my shopify store, if a product price and stock in amazon US changes it updates on my shopify store.
