Best Practices for Modern API Design with GEFEG.FX
In this article, focusing on the functionalities of GEFEG.FX, we explore best practices for developing standards-compliant interfaces using API technology—a fundamental building block for sustainable and maintainable IT systems.
This article complements the EDIWheel Workorder project report by providing additional technical details on the API functionalities in GEFEG.FX.
Complex Requirements in Interface Design
When developing interfaces for data exchange with external partners, companies encounter typical challenges: A lack of standards-compliant documentation and missing validation of data streams often lead to errors and security risks. At the same time, uncoordinated approaches complicate future scalability and maintenance. Inconsistent structures and the absence of versioning strategies create technical debt, which in the long run hinders further development.
The key solution: Integrated design of interfaces and data formats
GEFEG.FX provides an integrated approach by combining various editors (functional areas). In addition to the OpenAPI Editor, the software includes other editors specifically designed for the creation of data formats based on established industry standards and user-defined data structures. These data structures can be integrated into the API Editor, enabling validation of incoming and outgoing data using schema files.
By merging interface design with data exchange format design, GEFEG.FX acts as a comprehensive tool for API development, from the initial design stages to documentation. This integrated approach supports consistent implementation and, through the use of data format schema files, enables systematic quality assurance of exchanged data.
Praktische Features für effiziente API-Entwicklung
Practical Features for Efficient API Development The API Editor in GEFEG.FX supports domain experts with numerous practical functionalities. Full compliance with the OpenAPI 3 format ensures that all created APIs meet standard requirements. Flexible export options in YAML or OpenAPI 3 format allow seamless reuse in other applications and systems. Existing data structures from JSON Schema or XML Schema can be directly imported and used as a foundation for new APIs, eliminating redundant data structure creation.
Another efficiency gain comes from the regularly updated international code lists, which can be integrated into APIs with just a few clicks. Customisation options for API responses and the integration of example values in API descriptions simplify implementation for external partners. These features not only streamline API development but also promote seamless collaboration with business partners.
With the OpenAPI Editor in GEFEG.FX, developers and domain experts have a well-designed tool that supports the entire lifecycle of API interfaces while ensuring data quality. A strong example is the EDI Workorder project, which was developed using the GEFEG.FX API Editor. The combination of user-friendliness and technical depth makes it the ideal solution for modern integration requirements.
