Sinch Functions — Node.js Runtime

Overview

Sinch Functions is in beta: free during the beta period, and the API may change before general availability.

Package: @sinch/functions-runtime (npm). Write TypeScript/JavaScript functions that answer phone calls, handle conversation webhooks, and serve custom HTTP endpoints.

Voice API v2 is what context.voice is and what a new function is written against. The unversioned name always means the current API: context.voice is v2. The v2 sections below lead this skill because developers.sinch.com does not yet have a Functions-on-v2 page. Existing Voice v1 functions keep running unchanged; see Voice v1 callbacks.

• sinch-cli — terminal commands (sinch functions dev, sinch functions deploy, etc.)
• Voice API v2 is covered by the sinch-voice-api-v2 skill; load it for the REST contract, SVAML v2 commands, and service configuration.
• sinch-functions-dotnet — the same concepts in C#
