What is the current state of API Documentation?
The importance of API documentation is well recognized. All sorts of software vendors offer API documentation solutions. Startups, small businesses, focus on high added value delivered through innovation and enterprises usually offer API documentation as a part of an API developer portal.
All of these solutions have one thing in common: A significant part of the API documentation is generated from a high-level API description.
The goal of an API developer portal is to serve various personas involved in API lifecycle by enhancing plain API documentation with other related information and capabilities such as
- API monitoring
- API lifecycle management
- API test reports
- API issue tracking
Where is API Documentation going in the future?
As the API economy matures, we will see rising demand for complete API developer portals which offer powerful integration capabilities. Also, we will see continuing attempts to fully automate the delivery of API documentation and API consumption.
In the distant future, we can expect adaptive clients using semantic API documentation to automatically adapt and to start consume APIs. The ultimate goal is to let machines learn how to communicate with each other, to establish true machine to machine communication, to minimize the human resources needed to connect software applications through APIs.
