Order Endpoints

Create checkout sessions and manage orders

The order flow follows a session-based checkout pattern:

1. Create a checkout session — locks the product version, pricing, and currency
2. Preview tax — calculates tax based on the customer’s billing details
3. Create an order — initiates payment and returns a PSP-hosted checkout URL
4. Cancel an order — cancels a pending (unpaid) order before payment completes

One-Time Order Status Values

Status	Description
pending	Order created, awaiting payment. Can be canceled.
completed	Payment succeeded, order fulfilled.
canceled	Order canceled before payment was completed. Terminal state.
