# 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
export TELNYX_API_KEY="KEY..."
The CLI reads TELNYX_API_KEY from your environment. Set it once in your shell profile.
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
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.
