API

The Switchboard SDK exposes the same core API across every supported language: initialize the SDK, create an engine from a JSON description, then drive it at runtime with callAction, setValue, getValue, and event listeners.

Pick the language you're working in for the call-by-call reference:

• C++ — the native implementation; every other language wraps this.
• Kotlin / Java — JVM wrapper for Android and server-side use.
• Swift / Objective-C — Apple-platform wrapper for iOS, macOS, tvOS, visionOS.
• JavaScript — web wrapper (WebAssembly under the hood).

Other reference material:

• JSON Schemas — the schemas Switchboard objects and their type descriptors conform to.
• Extension API Reference — for authoring your own extensions and node types.
