✨ Getting started

Configuration

To configure the SDK you need to provide required properties

Property	ENV	Default	Required
io.getstream.chat.apiKey	STREAM_KEY	-	Yes
io.getstream.chat.apiSecret	STREAM_SECRET	-	Yes
io.getstream.chat.timeout	STREAM_CHAT_TIMEOUT	10000	No
io.getstream.chat.url	STREAM_CHAT_URL	https://chat.stream-io-api.com	No

You can also use your own CDN by creating an implementation of FileHandler and setting it this way

Message.fileHandlerClass = MyFileHandler.class

All setup must be done prior to any request to the API.

Print Chat app configuration

Java	System.out.println(App.get().request());
Groovy	println App.get().request()
Scala	println(App.get.request)
Kotlin	println(App.get().request())
Clojure	println (.request (App/get))
