Problem Statement

Payment Intent System Problem Description Background Stripe processes billions of dollars of payments to businesses every day through dozens of different payment methods like cards, bank debits, and even paper cheques.

For example, for many payment methods, payments are not completed instantly and can take a few days to process and be confirmed or fail, while others are processed much more quickly. Stripe abstracts this payment flow with a simple state machine object called a Payment Intent. Today, imagine you are an engineer working at Stripe in its early days.
