Channels API libraries

Sending and receiving messages using the Channels API requires libraries. In this section you'll find libraries for a variety of platforms.

Channels libraries are divided into 2 categories:

Client libraries predominantly consume messages using a WebSocket interface. Think of them as subscribers, although it's possible to publish messages using Client Events.
Server libraries publish messages, request information using our HTTP API, authenticate channel subscriptions, and handle Webhook calls. Think of them as publishers, although it's possible to subscribe to messages using Client Event Webhooks.
