Overview of Processing Klarna Transactions

This section provides an overview of the two methods for processing a payment using Klarna, as well as the order in which to send the Klarna API requests for these two methods.
There are two methods for processing a payment that are determined by how the customer accesses their Klarna account to complete the checkout:
Hosted Order Page
The customer is redirected to a Klarna-hosted order page (HOP) to complete the checkout. For overview information about how to process a payment using the HOP method, see HOP Session Workflow.
Inline
The customer uses the Klarna widget that is installed into the merchant website to complete the checkout. For overview information about how to process a payment using the inline method, see Inline Session Workflow.
For information about how to install the Klarna widget into the merchant website, see Widget Installation for Inline Workflow.
