Shopify + Patreon Login Integration

I’ve been searching on how to integrate Patreon Login capabilities into Shopify as a way to unlock specific content, etc but to no avail. Is there a good starting point beyond the OAuth as a tutorial in order to make this a possibility?

There isnt any specific tutorial for Shopify. Everything should be possible to implement over OAuth. Check already existing and widely used examples like the PHP lib or the WP plugin.
