I am building a node-express Shopify app and I found out that the app install path is the same as the app admin config page path.
What I did so far is when after an install happens I store the domain and access token in the DB, and when I access the route again then I verify if I have a value in DB
for a specific shop domain.
The problem is with this approach that I need some kind of verification for a reinstall event? from what I read the access token is permanent but I am not so sure.
Any advice would be appreciated!
