Which two API objects are fundamental in constructing pricing models on Stripe?

The primary components of Stripe's pricing models are the Product and Price API objects. The Product object represents the item or service that a business offers and includes details such as the product name, description, and any relevant metadata. It serves as the foundational unit around which pricing structures are built.

The Price object, on the other hand, defines how much a product costs and includes information such as pricing in particular currencies, billing intervals for subscriptions, discounts, and any applicable tax settings. Together, these two API objects enable businesses to create a variety of pricing models, including one-time charges and subscription plans.

While the Invoice and Customer API objects manage financial transactions and client lists, respectively, they do not define pricing models. Likewise, the Charge and PaymentIntent objects are focused on processing transactions rather than establishing pricing structures. Transaction and Refund API objects relate to the management of financial exchanges rather than the configuration of pricing itself. Thus, the Product and Price API objects are indeed fundamental to constructing pricing models on Stripe.
