Software Development Kit (SDK) is an API: a programming package that enables a programmer to develop applications for a specific platform that typically includes one or more APIs, programming tools, and/or documentation.
Bandwidth provides SDKs for Java, NodeJS, Python, PHP, C#, and Ruby for our REST APIs. The SDKs allow developers to focus on their code instead of having to focus on formatting HTTP calls.
Using the Bandwidth-provided SDKs can help speed up development. As these features are announced, look out for new features and API endpoints in the SDKs.
