How do I use the Send WhatsApp node?

Add a Send WhatsApp node and connect it from the previous step. In Configure, choose Message Type: Auto Response (conversation template) or Template (Meta template). Select the template and, if needed, the Auto response template for reply. Fill recipient (e.g. {{sender}} or a variable) and template variables (per placeholder {{1}}, {{2}}, etc. or via variable picker). If the template has media, select it. The node has Delivered, Failed, and optionally Continue ports—connect them to the next steps (e.g. success message, retry, or error handling).
