How do I add one-time and recurring products to the app?

You can add products to your Stripe account, and they'll show up in the Payment for Stripe app.

Start at dashboard.stripe.com/products/create. For one-time products, follow this guide: How do I add multiple Prices to a product?

You can also set a product to Recurring, which lets you offer subscriptions on different cadences — daily, weekly, monthly, yearly, and so on.
