Pulsar client APIs allow you to create and configure producers, consumers, and readers; produce and consume messages; perform authentication and authorization tasks, and so on via programmable interfaces. They encapsulate and optimize Pulsar’s client-broker communication protocols and add additional features using Pulsar primitives. Pulsar exposes client APIs with language bindings for [Java](pathname:///docs/client-libraries/java), [C++](pathname:///docs/client-libraries/cpp), [Python](pathname:///docs/client-libraries/python), [Go](pathname:///docs/client-libraries/go), [Node.js](pathname:///docs/client-libraries/node), [WebSocket](pathname:///docs/client-libraries/websocket), and [C#](pathname:///docs/client-libraries/dotnet).
