We make use of Axway's API gateway API management tool.
Its integration with middle wear is similar to ESB. We provide integrations as we are a swift services bureau. We've got customers that are banks and in some use cases. We integrate these banks with their own back office and we tend to provide integration for that.
We also make use of the solution to build a marketplace of financial services, which is basically our own solution.
For other customers, we do integration of the various source systems, back-office systems, legacy systems, etc. We also do file transformation where we take messages for customers in their environments and translate it to industry formats.
