Submarine exposes two key APIs, for which detailed Open API specifications are available.
The Customer API is exposed to a Shopify theme (or headless storefront) and allows authenticated customers to manage their stored payment methods and subscriptions.
You can read the overview of the Customer API or jump straight to the Customer API Reference.
The Admin API is available to back-end integrations to perform tasks like authorising and capturing payments against tokenised payment methods.
