Overview

This node operation sends a WhatsApp message containing a text with a link to a specified contact. WhatsApp automatically generates a preview for supported links such as YouTube videos, websites, and articles. This is useful for scenarios where you want to share rich link previews with contacts, enhancing message engagement and providing more context.

Use Case Examples

1. Sending a YouTube video link with a preview to a friend.
2. Sharing a website link with an automatic preview to a customer via WhatsApp.

Troubleshooting

• Ensure the 'To (Contact)' field is correctly formatted as phone_number@s.whatsapp.net to avoid sending errors.
• Verify that the link in 'Text with Link' is a supported type for WhatsApp link previews (e.g., YouTube, websites).
