API Documentation Auto-Generation

Australia’s postal service, Auspost, uses APIs to connect to mobile apps, delivery third-parties, eCommerce stores, other postal services and more, each with different requirements and permissions. But by late 2020 it was finding its internally built developer portal lacked important functionality, including no search functionality making it hard for developers to locate APIs from a steadily growing list, lack of support for the OpenAPI standard, and limited ability for developers to test real-life requests with try-out functionality. Auspost addressed these limitations by deploying technology from Redocly that includes the ability to search all documentation and to try out requests using multiple authentication options. The result was a reduction in developer bounce rate from the portal from 30% to 1.75% and 21 new APIs published in four months, according to a Redocly case study.

Funxtion is an API-first company based in the Netherlands that serves thousands of exercise videos and hundreds of virtual classes each month to more than 1,000 gyms in 25-plus countries. The company uses API-management and documentation technology from Trebble to streamline governance, debugging, and decision-making. Treblle allows Funxtion engineers to see exactly what’s causing an API to fail and provides a score on the performance, security, and quality of its APIs along with areas of improvement. According to a Trebble case study, implementation of Trebble has resulted in a 91% improvement in API performance scores, 15x improvement faster debugging, and saved hundreds of developer hours.

The global market for API document-management software is project to grow from $1.9 billion in 2025 to $5.5 billion in 2035, a compound annual growth rate of 11.2%, driven by demand for efficient API integration and documentation, according to market research firm Wise Guy Reports.
