APIs on complex IS

Expose a business information system to its ecosystem, cleanly

01 Problem

Your IS was built over the years: valuable data, but a system never designed to be opened up. Undocumented schemas, uneven security, no clear API layer. And yet: the mobile app, partners and new web frontends need to plug in.

02 Solution

Design and implementation of a clean REST API layer on top of the existing system. API Platform to industrialise, OpenAPI to document for consumers, comprehensive documentation for developers and tests to validate non-regression.

Methodology

Mapping of data and target use cases before any code.
Creation of UML schemas to discuss needs with the technical team.
Resource-oriented REST design, not a direct mirror of the database.
Implementation with API Platform to limit boilerplate.
Auto-generated OpenAPI documentation, always up to date.
Authentication and authorisation tailored to context (JWT, OAuth, API keys).
Fine-grained rights management.
