The API - powered by Finanz Informatik
With the wallis.Bank-API, you develop innovative services and new business models - together with and for Sparkassen and their association partners. The implementation is carried out with the support of Finanz Informatik and also enables integration into the sales management of the Sparkassen. In this way, your services can also be integrated into the advisor applications and online services of the customers of selected Sparkassen – for example via the Internet branch, i.e. the online banking of the Sparkassen, or the banking app.

'State of the art' API authorisation

Your options
With the wallis.Bank-API, you use interfaces in the core banking system (One System Plus, or OSPlus for short) of the Sparkassen to integrate released data or functions into your products and services. At the same time, you can expose your own APIs accordingly and thus enable a corresponding integration in OSPlus. Thanks to its Service Oriented Architecture (SOA), OSPlus offers an architecture that allows you to quickly orchestrate new APIs for all banking-related topics – for example, for services related to loans, products, document management and much more. The powerful core banking system comprises more than 3,000 functions that can be exposed via APIs.
Together with Finanz Informatik, we are happy to provide you and your partners, for example a Sparkasse or other association partners, with an API that we have customised exclusively for you. You and your partner Sparkasse can thus concentrate on the essential functions. You receive an exclusive, streamlined and thus simpler documentation of the functions exposed for you.
