We take our developer documentation very seriously, especially our API Reference. The reference docs are generated from a machine-readable description of each API, in OpenAPI format. This makes maintaining the docs easier for us, but also provides benefits to users such as access to tools that understand these files. Users can import OpenAPI spec files into Postman to create a collection of API requests, generate local reference documentation using tools like Nexmo OAS Renderer and ReDoc, and even mock APIs locally during development with tools like Prism from Stoplight. These approaches make it easier for users to interact with our APIs and improve their integration experience.
