How to verify the Access Token on the Shopify_App splash Screen

When the app review team uninstall and reinstall my app with their automated tools, they are getting an error because the uninstall webhook has not yet triggered the delayed job to delete the Shop record. I think that's then tripping up the install process because it is finding the old shop record with an invalid access token.

I've been advised that:

You should not be relying on an uninstalled webhook to determine a shop's status with your app. instead, each time a shop hits your app,

you should make a request to your server to first determine if the access token you have for them is valid (if so, they have your app installed - if not, redirect to OAuth) and then from there check for a valid charge ID using the billing API (if not, redirect to billing page).

How should I check the api key validity? When the app is installed they are redirected through splash page, so I need to somehow know if it's a new install and if it is, check the access token somehow?

It's really hard to tell what's wrong without knowing your architecture or request auth flow, so the solution could be somewhere else. Embedded apps redirect to shopify domain where Shopify checks if app URL is added to the store. If not it will return "There is no page at this address".

Answering your question -> the easiest way would be to make an API to /admin/shop.json request and see if you get a 401.
