Access data of different stores using Flask (python)

Shopify Apps
1

Hello folks,

I’m trying to build my first Shopify app using Python, I would like to know about :

  1. How i can implement the authentication part with the Stores.

  2. Does it’s possible to retrieve the stores orders once a new order is registered?

3)How i can integrate my front end app in the store when the merchant install it.

I’m a bit lost, so any help would be appreciated.

Thank you.
