Automate checkout testing inside VS Code Copilot

The `create_payment_session` tool allows your development team to initialize payment sessions without leaving their VS Code Copilot workspace. VS Code Copilot reads your local test schemas, builds the Klarna order lines, and returns the session payload instantly. Your team can share this MCP Server configuration across the workspace, allowing everyone to run `get_payment_session` in VS Code Copilot to inspect active checkout states. This keeps your entire engineering team aligned on the Klarna integration spec.

Manage the order lifecycle with this MCP Server

The `create_klarna_order` tool turns authorized customer tokens into formal orders directly from your VS Code Copilot chat panel. Developers can quickly test how your backend handles incoming Klarna order confirmations without manual API testing clients. When testing shipment workflows, your team uses `capture_klarna_order` in VS Code Copilot to settle funds against those test orders. This ensures your fulfillment microservices respond correctly to the Klarna capture event before going to production.

Process refunds and cancel pending authorizations

The `refund_klarna_order` tool executes return transactions directly from your team's shared VS Code Copilot workspace. VS Code Copilot maps the refund amounts, adjusts the Klarna line items, and updates the gateway state to keep your test ledger accurate. If a test transaction needs to be discarded, `cancel_authorized_order` releases the hold on the Klarna funds. Developers then run `get_order_details` in VS Code Copilot to verify that the order status has successfully transitioned to canceled.
