Open Banking Framework | API standards | Security Protocols

An open banking framework is the structured approach that guides how financial institutions, third-party providers (TPPs), and consumers interact within the open banking ecosystem. It sets the rules, technical standards, security protocols, and best practices that ensure open banking operates smoothly, securely, and in compliance with regulations like the Payment Services Directive 2 (PSD2). 

At Samlink, we help banks navigate and implement these frameworks, ensuring a seamless transition into open banking while maintaining compliance and efficiency. 

Core Elements of an Open Banking Framework

Regulatory Guidelines

The foundation of any open banking framework is regulatory compliance. In Europe, PSD2 mandates that banks open their APIs to licensed third-party providers, enabling secure data sharing and payment initiation. Compliance with regulations like GDPR for data protection is also essential. In addition to PSD2, upcoming regulations such as PSD3 and the SEPA Payment Account Access (SPAA) scheme are shaping the next phase of open banking in Europe, focusing on improved API access, enhanced consumer rights, and monetization models for premium services. 

API Standards

APIs (Application Programming Interfaces) are the key enablers of open banking. Frameworks provide standardized approaches for API design and implementation, ensuring compatibility across different institutions and regions. Common standards in Europe include: 

  • Berlin Group’s NextGenPSD2 
  • UK Open Banking Framework 
  • ISO 20022 for financial messaging 

Security Protocols

Security is at the heart of any open banking framework. Key components include: 

  • Strong Customer Authentication (SCA): Multi-factor authentication to enhance security. 
  • OAuth 2.0 and OpenID Connect: Standard protocols for secure authorization and authentication. 
  • Data Encryption: Protecting data during transfer and storage. 

Customer Consent Management

Open banking frameworks emphasize giving customers control over their data. Clear guidelines for obtaining and managing customer consent ensure transparency and trust. 

Monitoring and Reporting

Robust frameworks include processes for real-time monitoring, logging, and reporting. This helps detect fraud, ensure system performance, and maintain compliance with regulatory requirements. These monitoring tools also support proactive risk management, including fraud detection through behavioral analytics and anomaly detection systems. 

Why a Well-Defined Framework Matters

A clear and robust open banking framework delivers several key benefits: 

Consistency: Ensures that all stakeholders (banks, TPPs, fintechs) operate under the same standards. 

Security: Provides confidence that data is handled securely and ethically. 

Scalability: Supports the growth of open banking services without compromising performance. 

Compliance: Simplifies adherence to PSD2, GDPR, and other regulatory requirements.
