    Connect financial solutions into one seamless ecosystem
    open banking integration services

    Open Banking provides regulated access to financial data via APIs, but its adoption in production can be complex and demands special expertise. Its integration is advanced due to regulatory requirements, varying API implementations across banks, and high security expectations.

    PLANEKS provides Open Banking integration services for fintech companies and financial platforms that want stable, compliant access to banking APIs. We have extensive experience implementing secure integration layers in Python that fully comply with the Revised Payment Services Directive (PSD2) and Open Banking standards. Our deep domain experience enables us to achieve high-performing solutions, seamless data flows, correct consent handling, and long-term maintainability.

    What we do

    Our Services

    Open Banking integration outsourcing requires a vendor experienced in regulation, bank systems, and production-grade financial APIs. PLANEKS provides seamless Python-based connections with clear responsibility boundaries and stable long-term operation. We take over the crucial aspects like design, implementation, testing, and ongoing enhancement in line with your security and compliance requirements.

    Bank API Integration

    Our team implements direct integrations with bank APIs, covering both Account Information Services and Payment Initiation Services. Our engineers configure secure authentication flows, manage the consent lifecycle, and ensure effective handling of bank-specific API behavior. In case banks expose non-standard or partially compliant interfaces, we isolate inconsistencies at the connector layer to protect core systems.

    Third-Party Provider (TPP) Integration

    Many Open Banking ecosystems rely on aggregators or platform providers to optimise multi-bank access. We integrate and customize TPP solutions, creating standardized API layers that abstract differences between banks while offering control over data quality, performance, and compliance. As a result, clients scale the integration scope without pushing core logic into TPP platforms.

    Benefits of Open Banking Integration

    Why Outsource Open Banking Integration

    Open Banking integration services can be delivered most effectively with two main cooperation models: in-house and outsourcing. The in-house model demands ongoing investment in specialized knowledge, tooling, and maintenance. Most organizations opt to partner with a dedicated Open Banking integration team, such as PLANEKS, to achieve clearer timelines, reduced risk, and more efficient use of internal resources.

    Access to Specialized Open Banking Expertise

    Open Banking requires aligning regulation, security, and scalable system architecture. Our domain-specific experience with PSD2, Strong Customer Authentication, consent models, and real bank API behavior ensures a reliable, compliant Open Banking integration. With PLANEKS, your banking integrations are kept resilient, secure, and ready to scale across financial institutions and markets.

    Reduced Risk

    Bank APIs are growing, making regulatory interpretations dynamic and changing. Here, our team takes over tracking these changes, including monitoring API updates, managing version migrations, and validating compliance. We help you minimize the risk of service disruptions, data inconsistencies, or regulatory gaps that can emerge when APIs and partners change.

    Faster Time to Market

    New Open Banking implementations often start when companies need to launch a product, meet regulatory deadlines, or formalize partner integrations. Outsourcing helps you streamline delivery by using the deep specialization of our team, who are already acquainted with Open Banking standards, bank onboarding processes, and typical implementation bottlenecks. With our solid engineering discipline, integration approach, and established testing workflows, you can reduce ramp-up time and get your products to production while achieving top quality.

    Lower In-House Development Costs

    Maintaining Open Banking integrations internally requires dedicated engineers, ongoing training, and long-term operational ownership. However, this same process can be successfully outsourced to your specialized tech vendor. The fixed costs needed for on-premise support are converted into a scalable delivery model that reflects the genuine integration needs. Your internal teams remain focused on crucial business services, while integration complexity is handled by our experts equipped to manage it efficiently.

    Advantages of Python

    Why Python for Open Banking Integrations

    Python is a tried-and-true choice for successfully handling the technical and regulatory requirements of Open Banking. Integrations in this space engage heavy API use and dynamic data flows, demanding clarity, correctness, and flexibility. Our strong Python expertise and a resilient stack of technologies keep systems high-performing and scale smoothly through regulatory and API changes.

    Ideal for API-Heavy, Data-Driven Systems

    Open Banking integrations require managing large volumes of API calls, authentication flows, and structured financial data. Python has excellent frameworks and libraries that can be used to develop robust API clients and services, offering accurate oversight over request handling, error handling, and data validation. These qualities are vital for enabling account aggregation, payment initiation, and consent-managed data access.

    Strong Ecosystem for Fintech and Security

    The Python ecosystem has mature libraries for cryptography, secure key management, OAuth2 and OpenID Connect, and logging for compliance. These are necessary for implementing Strong Customer Authentication, managing tokens, and ensuring auditable access to data. The active adoption of Python in fintech also provides long-term support and established patterns for working in a regulated space.

    Scalable, Async-Friendly Architectures

    Open Banking systems require handling concurrent requests to multiple banks within rate limits and latency requirements. Python enhances clarity and maintainability, supporting efficient compliance, lowering operational risk, and keeping integrations performing smoothly after deployment. Using this technology, we substantially lower operational risk due to regulatory changes while keeping integrations reliable after launch.

    Clean, Maintainable Code for Long-Term Compliance

    Both Open Banking API integrations and regulatory requirements are in constant flux. Python offers a foundation to build a highly maintainable codebase that not only supports long-term compliance but also makes it more straightforward to manage regulatory updates, liquidating possible disruptions and keeping integrations resilient.

    Start Your Open Banking Integration Project

    We build integration architectures that handle bank-specific behavior, authentication flows, and regulatory controls from the outset. Through cooperation with PLANEKS, our clients can expand Open Banking use cases while maintaining compliance, data resilience, and software stability.

    Security, Compliance & Regulatory Readiness

    Security & Compliance

    From the initial architectural solutions, integrations are established and operated in line with security and compliance requirements. In Open Banking integrations, we apply strong permission controls, secure financial information, and provide complete audit trails for compliance purposes.

    Secure Authentication and Authorization

    Open Banking and API integration are supported by robust authentication mechanisms to secure both customer data and payment operations. We implement secure authorization flows based on OAuth 2.0, mutual TLS, and Strong Customer Authentication, ensuring that access is delivered only within approved scopes and consent boundaries. Rotation, revocation, and token handling ensure minimal exposure and prevent unauthorized access throughout the session and during permission updates.

    Encryption and Data Protection

    Sensitive financial data should be protected both while in transfer and when stored. We leverage industry-standard encryption protocols to secure communication with bank APIs and ensure sensitive data is stored using strong cryptographic controls. Permissions are set by design to restrict access, reduce unnecessary data retention, and ensure storage complies with regulatory minimization rules.

    Audit Logs and Traceability

    An essential requirement for regulated systems is that they should be explainable and auditable. To this end, we design logging and traceability mechanisms that capture authentication events, consent changes, API interactions, and data access paths. The audit trails support regulatory reporting, internal reviews, and incident analysis without impacting system performance or data integrity.

    Compliance-Aware Architecture for PSD2 and Open Banking

    Integration components are structured to reflect PSD2 roles, consent lifecycles, and data access boundaries. We make sure regulatory adherence is maintained despite changing APIs, scaling systems, or extending bank integrations. In this way, our experts deliver complete visibility, auditability, and consistent access control across the integration layer.
