WhatsApp Output node
Sends the flow's response back over WhatsApp to the conversation that triggered it — or to any number your automation targets.
WhatsApp Output (whatsapp_output) closes the WhatsApp loop: it sends the reply back to the sender (or a specified number) through your connected session.
Configuration

- Node ID / Name — the identifier used in variables and the display name on the canvas.
- Message — the text/variable to send.
- Recipient — defaults to the conversation that triggered the run.
Inputs & outputs
