API writer

An API writer is a technical writer who writes documents that describe an application programming interface (API). The primary audience includes programmers, developers, system architects, and system designers.

An API is a basic library consisting of interfaces, functions, classes, structures, enumerations, etc. for building a software application. It is used by development teams to interact with and extend the software. An API for a given programming language and system may consist of system-defined and user-defined constructs. As the number and complexity of these constructs increases, it becomes very tedious for developers to remember all of the functions and the parameters defined. Hence, the API writers play a key role in building software applications.

Due to the technical subject matter, API writers must understand application source code enough to extract the information that API documents require. Some common tools used by API writers include computer software that extracts documentation placed by programmers in the source code in a structured manner, preserving the relationships between those comments and the programming constructs they document.

API writers must also understand the software platform/product and document the new features or changes as part of the new software release. The schedule of software releases varies from organization to organization. The writers need to understand the software life cycle well and integrate themselves into the Systems Development Life Cycle.

API writers in the United States generally follow The Chicago Manual of Style for grammar and punctuation.

API writers typically possess a mix of programming and language skills; many API writers have backgrounds in programming or technical writing.
