All finAPI customers must migrate to XS2A interfaces before the deadline given by the National Financial Supervisory Authorities (BaFin, FMA). This migration must be actively performed by finAPI customers by connecting the new XS2A interfaces to existing bank connectionsusing new finAPI services.

General migration principle

Since mid September, finAPI Access provides the means to migrate to new XS2A interfaces. The migration of a bank connection can be performed by executing one simple new service call to connect a new XS2A interface to an existing bank connection. This way, existing data is kept and can be updated through new XS2A interfaces. finAPI customers can choose for themselves when they want to perform the migration for which (group) of their customers. Legacy interfaces and XS2A interfaces can be used in parallel in separate bank connections until BaFin ends the exemption period.
