Google Cloud Function to scrape retail website

I need to create a Google Cloud function that is triggered by an entry in Firestore database. The function should take a product sku from the database, go out to the retailer's website, fetch and write to another database table (document) the product details (price, description, thumbnail url).

Here's an example...
Product Code: 007040170 q
URL: https://www.target.com/s?searchTerm=007040170
Response: {}

Thank you!
