Apply for API credentials
In order to integrate with any of Klarna's APIs you will need a set of credentials. These credentials are comprised of two elements:
- Merchant ID (eid) - a unique number that identifies your e-store
- Shared secret - a string which is associated with your Merchant ID and is used to authorize use of Klarna's APIs
Note: It might take up to one day for us to create the required credentials for you.
