Overview
This node enables sending WhatsApp contact messages via the Green API service. It is part of a broader integration that allows executing various WhatsApp messaging actions or listening for incoming webhooks from Green API.
The Send Contact operation specifically sends a contact card to a specified WhatsApp chat. This is useful in scenarios where you want to share contact information directly within a chat, such as sharing a colleague's phone number, business contacts, or customer support details.
Practical examples:
- Automatically sending a new customer's contact info to a sales team group.
- Sharing emergency contact details in a private chat.
- Distributing company directory contacts through WhatsApp broadcasts.
