Install and authenticate the flowctl CLI for Estuary. Use when setting up flowctl for the first time, troubleshooting authentication, upgrading to the latest version, or configuring programmatic access for CI/CD. Use when user says "install flowctl", "set up flowctl", "flowctl auth", "how to authenticate", "token expired", "not authenticated", "FLOW_AUTH_TOKEN", "CI/CD setup", "programmatic access", "upgrade flowctl", "flowctl not found", "command not found flowctl", "Exec format error", or "flowctl on Windows".

flowctl is Estuary's CLI for managing captures, materializations, collections, and derivations from the command line.
brew tap estuary/flowctl
brew install flowctl
sudo curl -o /usr/local/bin/flowctl -L 'https://github.com/estuary/flow/releases/latest/download/flowctl-multiarch-macos' && sudo chmod +x /usr/local/bin/flowctl
sudo curl -o /usr/local/bin/flowctl -L 'https://github.com/estuary/flow/releases/latest/download/flowctl-x86_64-linux' && sudo chmod +x /usr/local/bin/flowctl
No native Windows build exists. Use one of:
Note: On ARM-based Windows machines (e.g., Snapdragon/aarch64 under WSL), the x86-64 binary won't work (Exec format error). There is no official ARM build yet — use a remote x86-64 environment or build from source.
flowctl auth login
This opens your browser to the Estuary dashboard's CLI-API tab. Copy the access token and paste it into the terminal.
Note: Access tokens are short-lived (~1 hour). You'll need to repeat this when the token expires.
For non-interactive environments, use a long-lived refresh token:
export FLOW_AUTH_TOKEN=<your-refresh-token>
Important: If a config file exists for the current profile, flowctl ignores FLOW_AUTH_TOKEN. Use a separate profile to avoid conflicts:
flowctl --profile ci catalog list
The refresh token expires after 90 days of inactivity — each use resets the clock.
Common CI mistake: Don't run flowctl auth token --token $FLOW_AUTH_TOKEN in your scripts — that command is for interactive token exchange only. Just set the env var and run flowctl commands directly.
flowctl --version
Quick test that authentication works:
flowctl catalog list --output json | head -5
brew update && brew upgrade flowctl
Re-run the install command for your platform — it overwrites the existing binary.
| Problem | Solution |
|---|---|
command not found: flowctl | Re-run the install command, or check that /usr/local/bin is in your PATH |
You are not authenticated | Run flowctl auth login — your token likely expired |
Exec format error | Wrong binary for your architecture — ARM machines need an x86-64 environment (see Windows section) |
FLOW_AUTH_TOKEN ignored | An existing profile config takes precedence — use flowctl --profile ci <command> |
Header of type authorization was missing | Token didn't save correctly — re-run flowctl auth login and paste carefully |
Failed to locate sops | Only needed for local secret encryption — install sops if using encrypted configs |

Create a capture for ANY Estuary connector using dynamic schema discovery.

Use when user says "capture from <source>", "stream from <source>", "connect <source> to Estuary", or "set up <source> capture" and no connector-specific skill exists.
