BNP Paribas Fortis
Cyrex partnered with BNP Paribas Fortis to design and deploy a PSD2-compliant Developer Portal with integrated API sandbox capabilities, supporting secure open banking initiatives and external developer integrations.
The Challenge
Building a Secure PSD2-Compliant Developer Portal
BNP Paribas Fortis, part of the BNP Paribas Group, delivers secure and innovative financial services across Europe. With the rise of PSD2 and open banking requirements, the bank identified the need for a professional Developer Portal that would:
- Provide secure API access to partners and developers
- Support open banking initiatives
- Offer sandbox environments for safe testing
- Align with PSD2 compliance requirements
- Maintain the highest security and reliability standards
Although BNP Paribas Fortis had strong internal capabilities, they required specialized expertise to design and deploy a fully robust, secure, and scalable Developer Portal aligned with regulatory expectations.
The Cyrex Solution
PSD2-Compliant Developer Portal & API Sandbox Deployment
Cyrex collaborated closely with BNP Paribas Fortis to architect and implement a secure Developer Portal supporting the bank’s open banking strategy.
Developer Portal Architecture
The portal was designed to provide developers with:
- Clear API documentation
- Structured API product listings
- Secure authentication and access mechanisms
- Interactive console capabilities
- Dedicated sandbox environments
- Test data for safe integration validation
This created a controlled environment where partners could explore and test services without impacting production systems.
Sandbox Environment & Open Banking Enablement
A key component of the solution was the implementation of a secure API Sandbox environment, enabling:
- Controlled API testing
- Separation from live banking systems
- Structured onboarding for third-party developers
- Compliance with PSD2 and open banking requirements
Cyrex also provided guidance and knowledge transfer, ensuring BNP’s internal teams could maintain and expand the platform independently.
The Outcome
Secure Foundation for Open Banking Growth
- A fully operational Developer Portal
- Secure API sandbox infrastructure
- PSD2-aligned open banking capabilities
- Structured onboarding for external developers
- Knowledge transfer to internal teams for long-term sustainability
- The Developer Portal strengthened BNP Paribas Fortis’ position within the evolving open banking ecosystem while maintaining strict security and compliance standards.
