composio login
composio whoami
Opens a browser for auth, then prompts you to pick a default org and project. Use -y to skip prompts in scripts.
composio link gmail
composio link slack
composio link github
Each command walks OAuth once; the connection then persists.

"recipient_email": "[email protected]",
"subject": "Composio test",
"body": "Hello from the CLI"
}'
If the email arrives, you're connected.
