     "description": "The payments API is used to create a session to offer Klarna's payment methods as part of your checkout. As soon as the purchase is completed the order should be read and handled using the [`Order Management API`](https://docs.klarna.com/api/ordermanagement).  **Note:** Examples provided in this section includes full payloads, including all supported fields, required and optionals. In order to implement a best in class request we recommend you don't include customer details when initiating a payment session. Refer to [Initiate a payment](https://docs.klarna.com/klarna-payments/integrate-with-klarna-payments/step-1-initiate-a-payment/) section for further details.
