Yeah it’s a bit like that
Your user clicks a “connect” button in your app > goes to stripe either log in if he already has an account or registers a new one > redirects back to Bubble’s static URL and you save their “Stripe Seller ID” in a custom field. Use that seller ID in workflows to modify things in Stripe from your platform.
Keep in mind Stripe.js actually does not have a “connect” workflow (For standard accounts), so use Bubble’s default Stripe plugin for that. I actually asked CoPilot to add it to Stripe.js but they said they were busy atm, maybe later.
