The Nexmo Server SDK team has revisited their existing specifications to improve the developer experience for those using their APIs. They aim to make it easier for developers to quickly get up to speed with new libraries without much interference. The new specification focuses on flexibility, abstracting away HTTP-specific details and emphasizing convenience above all else. This change will enable a more modern and clean interface, making it easier for developers to use the SDKs and provide an experience similar to well-constructed libraries from their respective languages.
