  title: Stream Chat API (Server-side REST) Application Devices API
  description: 'Server-side REST API for Stream (GetStream.io) Chat. This is a curated subset of Stream''s published Chat protocol (https://getstream.github.io/protocol), grounding the endpoints modeled in the API Evangelist catalog against the real base URL and paths. The Chat API is addressed at https://chat.stream-io-api.com. Every request carries the application `api_key` as a query parameter and is authenticated with a JWT sent in the `Authorization` header together with a `Stream-Auth-Type: jwt` header. Server-side tokens (no `user_id` claim) are used for the operations in this document; client tokens are used to open the real-time WebSocket connection modeled in the companion AsyncAPI document.

    Path and method choices here are taken from Stream''s official chat-openapi.yaml (github.com/GetStream/protocol). Request and response bodies are represented generically; consult the linked protocol reference for the full schemas.'
