First of all, what you did here is brilliant! I am not a FrontEngineer but was able to learn this fast and gain some understanding with all the documentation you have. Kudos!
I was trying to see if you have plans to use or provide guidance on the newer stripe integration, it seems that it have redirect URL, and I was trying to see how will this work.
I wanted to second this. This is referenced elsewhere on this forum and it’s something that has been stated as being already in their plans.
Looking at the session redirects in the migration guide makes me cringe. They took something simple and made it twice as complicated in the name of dynamic products and pricing. Sweet.
