Interfaces & APIs for Public Administration: The key to digital sovereignty

** Public administration** in Germany is facing one of the biggest challenges of its history: the comprehensive digital transformation. The online access law (OZG) has given the start, but the true revolution takes place not only in the surface of digital forms, but deep in the IT architecture of the authorities. The key to this digital sovereignty lies in the consistent use of interfaces & APIs for public administration.

APIs (Application Programming Interfaces) are the invisible bridges that allow different software systems to communicate with each other and exchange data. They are the backbone of any modern, connected digital infrastructure. For the administration they mean not only a technical necessity, but a fundamental change in the way state services are provided. This blog post highlights in detail why a API strategy management is no longer optional, but is a must which specific application cases allow APIs administration and how the challenges can be mastered on the way to API-First administration.

Why APIs are indispensable for public administration

The introduction of APIs in administration is a decisive step in breaking up the rigid, monolithic IT systems of the past and creating a flexible, future-proof architecture. Benefits range from pure Efficient Management to basic redesign of interaction with citizens and businesses.

Acceleration of OZG conversion

The OZG obliges federal states and municipalities to offer their administrative services digitally by the end of 2022 (with a factual extension by OZG 2.0). Without standardized OZG conversion interfaces, this is hardly possible. APIs allow to quickly and easily connect specialist procedures to central portals. Instead of programming your own, complex integration for each digital power, standardized interfaces can be reused. This drastically reduces the development effort and accelerates the provision of digital services. The "One for All" (EfA) strategy, in which a country or community develops a digital solution and makes these others available, is fundamentally based on the existence of open and well documented APIs.

Increase efficiency and cost reduction

Manual processes, media breaks and redundant data acquisition are the biggest efficiency killers in administration. APIs automate data exchange between different registers and specialist applications. A classic example is the address change: instead of the citizen having to report it to several offices, a central API could automatically forward the information to the local registration office, the tax office and other relevant agencies.
