How to create a payment link in Stripe (via Lovable)

First, connect Supabase to your project. Then create products and pricing in Stripe, and set up Stripe test mode for trying things out. In Lovable, store your Stripe API key securely via 'Add API Key'—Lovable accepts Stripe secret keys (sk_test_... / sk_live_...) and restricted keys (rk_test_... / rk_live_...). Never paste keys in chat. Describe your needs in chat—Lovable generates checkout/portal Edge Functions, database tables with Row Level Security, and UI buttons. Deploy via 'Apply' before testing in production.
