How do I add Stripe payments to a Lovable app?

Stripe is Lovable's standard answer for taking money, and the workflow is: create a Stripe account, connect it through Lovable's integration settings, then prompt for the exact payment behavior you want. The more precisely you name the model, the better the result: 'add a Stripe checkout that charges $29 one-time for the premium plan and unlocks the dashboard' beats 'add payments.'

The three common patterns each have a phrase worth using in your prompt. One-time purchases use Stripe Checkout. Recurring billing uses Stripe subscriptions with a customer portal so users can cancel themselves. Marketplace payouts to sellers use Stripe Connect, which is more setup but is the correct architecture when money flows through you to other people.

Always build against Stripe test mode first (Lovable will use your test keys), run through the full purchase with Stripe's test card numbers, and verify that access actually unlocks and that failed payments behave sensibly. Only then switch to live keys. Skipping the test-mode pass is the most common way builders end up debugging payments with real customers.

Two production notes: make sure webhook handling exists so subscription cancellations and failed renewals update your app's access (prompt for it explicitly: 'handle Stripe webhooks for subscription cancelled and payment failed'), and never store card details yourself; Stripe's checkout keeps you out of PCI scope.
