Instantly bridge legacy banking APIs to modern payment gateways without custom code.
Enterprise fintech teams struggle to seamlessly integrate modern payment gateways into legacy banking systems, leading to significant delays in product rollouts.
LegacyPayBridge provides pre-built middleware connectors that translate legacy banking protocols into standard APIs for gateways like Stripe and Adyen. Teams upload their legacy API specs, select a gateway, and deploy a managed proxy in minutes. This eliminates weeks of custom integration work, enabling rapid product rollouts.
