slack chat send --channel "@username" --text "Hey!"

# Upload a file to a channel

Usage Guidelines

  • Always confirm the target channel or user before sending
  • Use #channel-name syntax for channels and @username for DMs
  • File uploads support PDF, images, text, and most common formats

Notes

  • Bot token must have chat:write and files:write scopes
