API-First Core Banking: How to Build an Open Finance Ecosystem with a Low-Code Platform in 2025
Discover how to build an open financial ecosystem with API-First Core Banking and low-code platforms. Complete guide to digital banking transformation in 2025.
In 2025, the financial sector is undergoing an unprecedented digital transformation. According to a recent study, over 70% of financial institutions consider infrastructure modernization as a top priority. This technological revolution is driven by two fundamental pillars: API-first architecture and low-code platforms.
In this rapidly evolving landscape, financial institutions face a major challenge: how to modernize their services while maintaining the stability and security essential to banking? The answer lies in adopting an API-first architecture coupled with a low-code platform, such as the one offered by Basikon, which enables building an open, flexible, and secure financial ecosystem.
The 2025 banking landscape is marked by increasing fragmentation of financial services. A business uses an average of four to five different providers for its financial needs: a traditional bank for deposits, a fintech for credit, a specialized provider for international payments, and various applications for treasury management. While this multiplication of players offers more choice, it creates increased complexity for businesses.
Facing this fragmentation, the API-first approach provides an elegant solution. As demonstrated by M3 Leasing, which successfully digitized all its processes in just four months using the Basikon platform, API integration enables creating a unified ecosystem where all financial services communicate seamlessly.
The benefits of such an approach are multiple:
Operational cost reduction can reach 40%, according to industry analyses. Process automation and elimination of manual re-entry significantly contribute to this optimization. The speed to market for new products is also multiplied, with financial institutions now able to launch new offerings three times faster than with traditional systems.
Security represents a crucial challenge in an interconnected financial ecosystem. According to an F5 report, security risks increase exponentially with system interconnection. APIs, which constitute the "front door" of sensitive systems, become prime targets for attackers.
To address these challenges, the Basikon platform integrates several security levels:
Robust multi-factor authentication ensures only authorized users access services. End-to-end encryption of data ensures confidentiality of sensitive information during transit between different systems. Real-time fraud detection systems continuously monitor transactions to identify any suspicious activity.
This comprehensive security approach allows financial institutions to benefit from open finance advantages while maintaining the highest level of protection for their clients and data.
Adopting a low-code platform represents a paradigm shift in financial services development. Basikon's Core Lending solution perfectly illustrates this evolution, enabling financial institutions to rapidly develop and deploy new products without requiring deep technical expertise.
Industry statistics are compelling: low-code platforms enable up to 70% reduction in development costs and multiply new product speed to market by three to five times. This increased efficiency is explained by several key factors:
Development simplicity allows business teams to actively participate in solution creation, reducing dependence on specialized technical resources. Component reusability accelerates development while ensuring solution consistency. Native integration with existing systems eliminates technical complexities usually associated with integration projects.
The Basikon platform stands out for its ability to combine the advantages of an API-first architecture with low-code simplicity. Preconfigured connectors enable rapid integration with major banking systems, payment service providers, and risk management platforms.
The M3 Leasing case is particularly revealing: using Basikon's Core Banking platform, the company was able to implement a complete financing management system, including white labeling, process digitization, and seamless integration with partner banks' information systems.
Financial institutions using Basikon report concrete results:
A 40% reduction in development costs thanks to the low-code approach. A significant acceleration in time-to-market, allowing new financial products to be launched three times faster. An improvement in customer satisfaction thanks to smoother processes and better responsiveness to market needs.
Evolution towards an API-first architecture supported by a low-code platform is no longer optional but necessary to remain competitive in the 2025 financial landscape. This transformation requires a structured approach and a reliable technology partner.
Financial institutions must prioritize three key aspects: infrastructure modernization to support an API-first architecture, adoption of a low-code platform to accelerate innovation, and implementation of a robust security strategy to protect their open ecosystem.
An API-first architecture places programming interfaces at the heart of the banking system, enabling standardized and secure communication between different financial services. This approach facilitates new service integration and creation of open financial ecosystems.
A low-code platform accelerates financial services development by reducing development costs by up to 70% and tripling speed to market. It also enables greater agility in adapting to market needs.
Security relies on several pillars: multi-factor authentication, data encryption, real-time transaction monitoring, and granular access management. These measures must be complemented by regular audits and continuous monitoring of third-party partner activities.
Return on investment typically manifests within 12 months of implementation, with operational cost reduction reaching up to 40% and significant acceleration in new product development.
The ideal platform must combine ease of use, security robustness, API integration capabilities, and scalability. It must also offer preconfigured connectors for major banking systems and comply with industry regulatory standards.
