RESTServer-Side Overview
Parts of Stream Chat are configured from your backend rather than from a client SDK. App settings, permissions, webhooks, push templates, data retention and campaigns are all set up with a server-side SDK or the REST API, authenticated with your API secret. That code never runs in your app.
Those pages used to appear in this sidebar. They now live in the server-side documentation, so the pages here stay focused on the code you ship to your users.

Languages
The server-side docs are published per language. Pick yours from the selector at the top of the page: Node.js, Python, Go, Java, Ruby, PHP or C#.
If you landed here because your client cannot connect, token generation is the usual cause. Tokens must be signed with your API secret on your server, so a client SDK cannot mint one. Start with Tokens & Authentication.
