python scripts to monitor websites

I want a couple of python scripts that use requests and soup that will monitor shopify websites for newly added items or when items restock. for example: [login to view URL] this program monitors websites that use shopify and everytime there is a restock or a new item added to site it sends a message to discord through http requests. if you add /[login to view URL] or /[login to view URL] to the end of a shopify sites link, you can see all of the products on the site, in XML or json format. the script should try both extentions in order to find the stock. i should also be able to add keywords to the script, so it only returns a message if the item that was picked up has the certain keywords. i also want to monitor: [login to view URL] everytime a new card is added to the site it should return a message.
