Triggers when WhatsApp call events occur
Join our community

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 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 trigger a workflow that logs every incoming WhatsApp call or sends a notification when a call is accepted.

Output

The node outputs JSON data representing the webhook payload received from the WhatsApp instance. The output structure includes all details sent in the webhook body under a body field.

Example output JSON structure:

{
  "body": {
    "event": "call.received",
    // ... other event-specific data fields
  }
}

Dependencies

  • Requires a WhatsApp instance (either session-based or server) configured to send call event webhooks to the URL exposed by this node.
  • No additional API keys or credentials are handled directly by this node; it relies on external WhatsApp infrastructure to push events.

Troubleshooting

  • No workflow trigger despite calls happening: Ensure your WhatsApp instance is correctly configured to send webhook events to the node’s webhook URL.
  • Workflow triggers but no data: Verify that the selected events in the node settings match the actual event types sent by your WhatsApp instance.
  • Error or empty response: Check that the webhook HTTP method is POST and that the payload contains an event field.
  • Multiple events not triggering: Confirm that the node’s "Events" property includes all desired event types.
