Sinch CLI

Overview

Sinch Functions and the CLI are in beta: free during the beta period, and commands may change before general availability.

The Sinch CLI (@sinch/cli, binary: sinch) is a unified command-line tool for the entire Sinch platform. It manages Sinch Functions (serverless), Voice applications and outbound calls, phone Numbers, Conversation messaging (SMS/WhatsApp/RCS and other channels), Fax, Elastic SIP Trunking, secrets stored in the OS keychain, and multi-project configuration profiles.
