Telnyx CLI

The Telnyx CLI provides command-line access to the entire Telnyx API. Every API endpoint maps to a CLI command — 946 commands covering messaging, voice, numbers, IoT, AI, and more.

Installation

# Homebrew (macOS/Linux)
brew install telnyx/tap/telnyx

# Go install
go install github.com/team-telnyx/telnyx-go/cmd/telnyx@latest

# Or download a binary from GitHub releases:
# https://github.com/team-telnyx/telnyx-go/releases

Authentication

export TELNYX_API_KEY="KEY..."

The CLI reads TELNYX_API_KEY from your environment. Set it once in your shell profile.

Command Discovery

The CLI is fully self-documenting. Use --help at any level to explore:

# Top-level resource list
telnyx --help

# Commands for a specific resource
telnyx messages --help

# Full usage for a specific command
telnyx messages create --help

Command Structure

Commands follow a consistent pattern:

telnyx <resource> <action> [--flag value ...]

Resources match API paths. Actions are list, create, get, update, delete, and resource-specific verbs.
