Connect your client's Klarna with a key they paste, and call its API through Operate As.

Service	Key	Base URL
Klarna	`klarna`	`https://api.klarna.com`

Your client also types their api username (Shown when you make API credentials in the Klarna Merchant Portal).

Connecting

Your client makes a API password in their Klarna settings and pastes it on their link. Operate As tries it with Klarna before saving it, and stores it encrypted. See Services connected with an API key.

Pass-through

Paths continue from https://api.klarna.com. Your Operate As key goes in Authorization; the client's access is added for you.

See Pass-through requests for the full request and response format.

When access ends

A key works until your client deletes it in Klarna. They can paste a new one on the same link at any time, and your workflows carry on without changes.

See Keeping access alive and Removing access.

  },

}
