Cascading Transactions
The Tietoevry E-commerce Payment Gateway (EGW) provides a Cascading mechanism that ensures maximum transaction reliability by automatically retrying failed payments through alternate processors or payment methods. While traditionally considered a failover tool, Cascading is also a merchant-facing business feature that improves conversion rates, optimizes cost strategies, and enhances the payment experience.
Configuration Options
EGW supports both platform-level cascading logic and merchant-level preferences through the Merchant Portal and Admin Portal.

Define fallback processors for each method
Merchant Preferences
Merchants can set acquirer order or fallback methods (subject to bank policy)

Limit the number of attempts per transaction
Error Type Filters
Define which error types trigger retries
Cross-Method Permission
Enable fallback across methods (e.g., Card → A2A)
