Overview
Work covers resource modeling, endpoint structure, request validation, pagination, error formats and authentication such as tokens or API keys. The API can be built as a new backend service or added to an existing codebase, with database access and role-based permissions where needed. You receive source code in your repository, automated tests for core endpoints and an OpenAPI specification that frontend or partner developers can work from.
