Stripe account, plugin install, and the one-button smoke test
If clicking the button opens a Stripe checkout page, you are done. Everything after that is just which fields you pass.
ACCOUNT: sign up -> verify -> Activate payments -> individual/company, legal details, address matching your ID (Aadhaar, PAN or bank statement in India), business and website details (your app needs real website, support and terms-of-service pages), public statement descriptor, phone, bank, 2-step authentication; approval 1-2 days; use Test mode meanwhile. PLUGIN: Plugins > Add plugins > official Stripe plugin by Bubble (check install count) -> choose Checkout version 3 -> paste Client ID (Stripe: Settings > Connect), publishable key and secret key (Developers > API keys, test mode) -> name it, upload favicon. TEST: Design > Button -> workflow Payments > Charge the current user with dummy email, amount 20, USD, store name, description, image -> preview -> Stripe Checkout opens.
The payment rail the detail page uses in Part 2 of Properties Details.
