I have an external API web service that interfaces with Shopify via several different methods. And these are connected via a registered Shopify private app.
From all I've read, I realize that Shopify isn't meant for this. Any suggestions as to best handle what I'm looking to do?

The lack of response leads me to believe this isn't doable. Which I've come to understand delving more into this. Which leads me to a second question.
Is there any way to store and reference a unique identifier on the Shopify back-end? I was trying to reference the 'now' Liquid variable, but have learned that this only reflects the current timestamp when the template was rendered. I've searched for any Liquid reference to a unique Session ID, but have come up empty.
This is an accepted solution.
This was worked around through creating a private app proxy (https://help.shopify.com/api/embedded-apps/app-extensions/online-store/application-proxies). I validate the signature from the proxy call, and that in turn is used to issue a JWT from my third-party app.
