Open Bank Project API Integration Services for US Banks and Fintech Companies

FintegrationFS is an API integration company, not the Open Bank Project API provider. We do not sell OBP licenses, issue API credentials, operate bank accounts, provide financial data, or approve banking access. Your organization must obtain the required platform access and permissions from the relevant provider. We develop, test, deploy, and maintain the technical integration around your approved environment.
What Is Open Bank Project API Integration?
Open Bank Project is an open-source REST API platform for banks and financial institutions. It can sit between backend systems and applications that need controlled access to banking data and services. The platform connects with existing systems and exposes functionality through prebuilt, standardized API endpoints.
An Open Bank Project API integration connects the platform with core banking infrastructure, payment services, CRM systems, customer databases, KYC tools, mobile apps, web portals, and approved third-party products.
This structured approach creates a maintainable integration boundary, making it easier to add applications, update backend systems, investigate incidents, and introduce new banking services without rebuilding the entire connection separately for every financial product.
Open Bank Project API Integration Services
Core Banking and Backend Connectivity
Our developers create connectors between Open Bank Project and your banking infrastructure. We review how accounts, balances, transactions, customers, counterparties, and payments are stored, then map those structures to relevant OBP resources.
Account and Transaction Data Integration
We create workflows that expose approved account information, balances, transaction history, counterparties, and related data to mobile apps, customer portals, internal dashboards, or partner systems.
Payment and Banking Workflows
Where supported by your environment, FintegrationFS can integrate payment initiation and other banking workflows.
Our team can implement validation, approval steps, idempotency, status handling, error recovery, audit events, and reconciliation. We can also connect fraud tools, compliance systems, notifications, and operational dashboards.
Developer Portal and Partner Programs
Open Bank Project includes a Developer Portal where developers can register applications and request access. Its API Manager helps administrators review connected applications and manage roles and entitlements.
We can customize application registration, access requests, documentation, support processes, and partner dashboards.
API Gateway and Access Management
Open Bank Project includes gateway capabilities for traffic control, access control, and rate limiting.
Our Open Bank Project API integration services can configure consumer limits, entitlement workflows, protected endpoints, logging, alerts, and operational visibility around your security model.
Sandbox and Proof-of-Concept Development
Open Bank Project offers sandbox capabilities with developer onboarding, synthetic data, prebuilt authentication and consent flows, and a broad API catalogue.
FintegrationFS can build proof-of-concept workflows, connect sample applications, prepare test scenarios, and validate the architecture without using sensitive live customer data.
Authentication and API Security
The current Open Bank Project codebase supports OAuth 2.0, OpenID Connect, Direct Login, and other authentication methods. Its official repository states that OAuth 1.0a support has been removed.
Our engineers can implement application registration, redirects, token handling, secure secret storage, token expiration, and access revocation.
We also consider encryption, least-privilege access, audit logging, protected configuration, and incident monitoring. Your security and compliance teams remain responsible for approving policies and deciding which information can be exposed.
