What Is a Hosted Chat SDK?
A hosted chat SDK is a client library backed by a vendor-run cloud service that adds real-time messaging and calling to an app. The vendor operates the servers; the developer integrates the SDK and APIs.
It is the fastest way to add in-app chat: no servers to size, patch or scale, and you pay as your app grows.
