Open Bank Project API

The Open Bank Project (OBP) is the leading open-source API platform: it delivers a RESTful interface for banks to securely launch financial-grade APIs and power a global FinTech ecosystem.

The Open Bank Project (OBP) is the global standard and API solution for the financial services industry, pioneering open banking concepts since 2010. It provides a RESTful interface, allowing developers to build customer-facing applications—like PFM solutions and online accounting integrations—without coding for disparate bank systems. OBP enables financial institutions to create, test, and manage APIs that ensure compliance with major standards (e.g., UK Open Banking, Berlin Group). The platform unlocks a wide range of use cases: this includes secure access to account information, initiating payments, and enriching transactions with metadata (tags, geolocation). OBP has advised over 100 banks and regulators globally, proving its robust, production-ready capability.
