Overview
This node integrates with the Go WhatsApp Web MultiDevice API to send various types of messages and manage WhatsApp interactions programmatically. Specifically, the Send Contact operation under the Chatting resource allows users to send a contact card (vCard) to a specified phone number or group ID on WhatsApp.
Typical use cases include:
- Automatically sharing contact information during customer support chats.
- Broadcasting new team member contacts to group chats.
- Integrating CRM systems to share contact details directly via WhatsApp.
For example, a business could automate sending a sales representative's contact card to a customer after an inquiry, facilitating easy follow-up communication.

Troubleshooting
