Node: Send WhatsApp Template

The Send WhatsApp template node (send_whatsapp_template) sends a Meta-approved template to the contact. It's the only permitted way to reach a customer on WhatsApp once more than 24 hours have passed since their last message (outside the customer service window).

When to use it

• Appointment reminders, payment reminders, abandoned-cart follow-ups, or any re-engagement outside the 24h window.
• Reopening a conversation with an inactive customer without risking Meta blocking the send.

Requirements

• The template must exist in the workspace's WhatsApp Templates and be in approved status with Meta.
• The contact needs a WhatsApp identity (or an active WhatsApp conversation) so the channel can be resolved.

Configuration

• WhatsApp channel: pick this first; the template list auto-filters to templates approved on that channel.
• Template (required): the template's real body is shown so you can verify what you're about to send.
• Body parameters: one value per {{1}}, {{2}}... the template uses; each value supports variables ({{contact.first_name}}). The editor locks the number of fields to the template's actual placeholders and shows a live preview of the final message.
• Header parameters (advanced): only if the template has a header placeholder.
• Button parameters (advanced, via JSON): for dynamic URLs or quick-replies.

Example

Workflow "24h appointment reminder": node with channel WhatsApp Support, template appointment_reminder (en), body parameter {{contact.first_name}} in position 1 and {{appointment.starts_at}} in position 2.

Tips

• If you need to reply within the 24h window, use Send message instead — it's simpler and doesn't need Meta approval.
• A template deleted on Meta still works during a grace period; after that the node can no longer send it.

Troubleshooting

• "Template not found" or "not approved": check the template's status in WhatsApp Templates; only approved templates can be sent.
• "No WhatsApp conversation could be resolved": the contact has no identity on that WhatsApp channel; confirm they've messaged that number before, or pick the correct channel.
