Bank Leumi Israel | Banking and Financial Services | 7830 | $11.6B | Israel | OpenLegacy | OpenLegacy Hub | API Management | 2023 | n/a |
In 2023 Bank Leumi Israel implemented OpenLegacy Hub to create an API first architecture as part of its open-banking and modernization program in Israel, using OpenLegacy Hub within the API Management category to expose mainframe capabilities as managed APIs. The implementation formalized API design and provisioning to support the bank's open-banking services and developer onboarding.
OpenLegacy Hub was configured to automatically generate microservices and OpenAPI files from mainframe CICS assets, delivering copybook to service automation reported as a five minute flow. The configuration eliminated manual OpenAPI authoring and enabled rapid creation and deployment of dozens of microservices, producing consistent API specifications and packaged service artifacts for downstream deployment pipelines.
Integrations focused on IBM CICS mainframe assets as the canonical transactional source, with generated OpenAPI artifacts consumed by development and integration teams to onboard services into the bank's open-banking stack. Operational coverage was centered on open-banking business functions and modernization initiatives in Israel, converting mainframe copybook definitions into RESTful service endpoints.
Governance shifted toward an API first methodology with standardized OpenAPI artifacts and automated service generation to reduce manual specification work and accelerate time to market as reported. The Bank Leumi Israel deployment illustrates how OpenLegacy Hub in the API Management category can automate copybook to service workflows and scale microservice creation from mainframe assets.

Citibanamex Mexico | Banking and Financial Services | 38000 | $4.3B | Mexico | OpenLegacy | OpenLegacy Hub | API Management | 2019 | n/a |
In 2019, Citibanamex implemented OpenLegacy Hub as an API Management solution to expose core mainframe banking functions as APIs to support a mobile first strategy in Mexico. The OpenLegacy Hub deployment focused on surfacing transactional and account services directly from the mainframe into API endpoints for digital channels, establishing an API abstraction layer that decouples mobile client delivery from back end transaction processing.
The implementation produced a working prototype that exposed six business workflows in two weeks, mapping account opening, payments and consumer credit workflows into reusable API services. Configuration emphasized rapid generation of API wrappers and orchestration capabilities to present cohesive business operations to mobile channels while maintaining core transaction pathways on the mainframe. OpenLegacy Hub was used to define endpoint contracts, model request and response payloads, and perform protocol translation to enable synchronous API consumption by mobile applications.
Operational scope centered on mobile channels and the product, engineering and operations teams supporting retail banking in Mexico. Governance shifted toward API centric release practices and API driven feature delivery, enabling product teams to deliver new mobile features faster and improving customer experience. The implementation narrative reiterates OpenLegacy Hub as the application used for API Management to accelerate Citibanamex’s mobile first initiatives.

Security Bank | Banking and Financial Services | 7200 | $1.0B | Philippines | OpenLegacy | OpenLegacy Hub | API Management | 2020 | n/a |
In 2020 Security Bank implemented OpenLegacy Hub to accelerate modernization of core-system APIs. The deployment exposed mainframe capabilities as business-level APIs to support customer-facing digital services across the Philippines, and the program was organized under an API Management initiative to surface transactional capabilities to modern channels.
Implementation centered on OpenLegacy Hub's API Management functionality, leveraging automated API generation and runtime adapters to wrap core system transactions as business APIs, and applying an API lifecycle model for design, testing, and publication. Configuration work included API modeling, schema transformation, and lightweight orchestration to translate mainframe services into RESTful endpoints consumable by mobile and web applications.
Integrations consolidated mainframe interfaces into the bank's digital services stack, enabling frequent endpoint provisioning and iterative delivery to customer-facing channels across the Philippines. Operational coverage focused on digital service delivery and integration velocity, with teams deploying complete integrations on a rapid cadence to support continuous feature rollout.
Governance introduced API cataloging, version control, standardized security controls, and testing workflows to manage published business-level APIs and onboard internal developers. The program reduced time to deployment by one third and averaged a complete integration every three days, enabling faster delivery of customer-facing digital functionality and improved operational efficiency.
