# Payment Flow
1. Merchant calls `/v2/session` with order and intent of `AUTH` or `CAPTURE`. Optionally, the merchant can send customer information
2. Sezzle returns order uuid and checkout URL.
3. Merchant redirects customer to Sezzle checkout URL.
4. Customer completes the Sezzle checkout and is redirected to the session complete URL.
* If the intent was to `CAPTURE`, Sezzle will capture the total order amount.
* If the intent was to `AUTH`, Sezzle will only authorize the total order amount and the merchant can call `/v2/order` later to release or capture amounts using the order uuid.
