The manual contains use cases, descriptions of functions and format of data. ### About the Service The Credit Cards Service retrieves information on the credit cards of the logged-in user, both where the user is the owner and holder of the cards, provided that the user is entitled to see these cards. The service shows information on cards in active use and cards in the legal collection process. It is also possible to get statements showing transactions on the cards according to the withdrawal period and payment period. ### Identity and Access Management Access control for the service follows the same model as the Arion online banking system, where users are authenticated with a username and password. Additionally, communications between the web service and the user’s system are signed with an electronic certificate. Corporate Banking can define the rights of corporate users so that corporate users can either have access to all cards for which the company is registered as user or holder or to no cards at all. The ID numbers of subsidiaries can be linked to the user so that the user has permission to view the credit cards of subsidiaries. Credit Cards Service is built on Arion Bank's own schema. The service has a defined WCF endpoint with a Mutual Authentication security model. The information transmitted between systems is encrypted over HTTPS, ensuring maximum security. For detailed instructions on authentication for B2B services, refer to the manual - [Authentication and Certificates](/b2b-2013-schema/b2b-services/b2b-setting-up-a-authentication-and-certificates.md). ### Web Paths The Credit Cards Service is available at the following URL: ### Schemas Schema descriptions, including WSDL files, are available at the following URL:
