I need to find a way to use a proxy in between too website. We have a retail website let's say : hoodie.com and we want that if the customer wants to access their account infos he will be redirected to : account.hoodie.com. The tricky thing is that we want to have an in between, let's say a middleware, that when the user clicks on the account tab on hoodie.com, he will have to connect to his shopify account and then redirected to the account.hoodie.com. I'm lost and can't find anything online to help me with it! I'm really new to shopify and only 10 months into web programming!
