AI-generated

Overview

This node triggers workflows in n8n when specific WhatsApp call events occur. It listens for incoming webhook POST requests from a configured WhatsApp instance and activates the workflow if the event matches one of the selected call event types.

Common scenarios where this node is beneficial include:

  • Automating responses or logging when an incoming WhatsApp call is received.
  • Tracking call acceptance or rejection events to update CRM systems or notify teams.
  • Integrating WhatsApp call status into broader communication or support workflows.

For example, you could use this node to start a workflow that logs every incoming WhatsApp call or sends a notification when a call is accepted.

    "body": {

Dependencies

  • Requires a WhatsApp instance (either session-based or server-based) properly configured to send call event webhooks to the URL exposed by this node.
  • No additional external API keys or credentials are managed by this node itself; however, the WhatsApp instance setup may require authentication and configuration outside of n8n.

Troubleshooting

  • No trigger on events: Ensure your WhatsApp instance is correctly configured to send webhook events to the exact URL path (whatsapp-call) exposed by this node.
  • Selected events not triggering: Verify that the event type sent by WhatsApp matches one of the selected events in the node's "Events" property.
  • Empty or missing payload: Confirm that the WhatsApp webhook is sending the expected JSON payload and that the HTTP method is POST.
  • Webhook URL inaccessible: Make sure your n8n instance is publicly accessible or tunneled so WhatsApp servers can reach the webhook endpoint.
