Mainframe & COBOL Services
Mainframe API Development & Integration
Add years of functional life and value to your mainframe by integrating it with other applications.
Why it matters
The systems your business can't stop
Your mainframe already holds the data and the logic your business depends on. The fastest way to extend it is often to connect it, not replace it.
We build the integrations that let new channels and systems use your mainframe, while keeping changes to the core to a minimum.
What we do
What's included
- API development for mainframe applications
- New back-end functions for web services
- Integration with digital channels and core systems
- Message format translation between systems
- ISO 8583 and card-network interfaces
- Integration across data centers and networks
In practice
What integration makes possible
- New digital-channel features on existing core systems
- Connections to card networks and processors
- Data shared between platforms after a merger
- Longer life for systems that already work
