Klarna integration

Klarna Buy Now Pay Later (BNPL) and payments platform API. Authorize and capture payments, manage post-purchase order lifecycle (capture, refund, cancel, extend authorization), generate reusable customer tokens for recurring charges, and reconcile settlements/payouts. Used by merchants worldwide to offer Pay Now, Pay Later, and Pay in Installments at checkout. The API is region-scoped: declare {api_host} per credential to target Europe (api.klarna.com), North America (api-na.klarna.com), or Oceania (api-oc.klarna.com), with matching playground hosts for testing. Authentication is HTTP Basic Auth using the merchant API username (UID) and password (secret) issued in the Klarna Merchant Portal.

Use Klarna from Claude Code, Cursor or Codex

Connect Klarna in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Klarna operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}
