Overview

This node integrates with Green API to enable enhanced WhatsApp automation, specifically supporting operations related to messages, groups, chats, and contacts. For the 'Message' resource and 'Send File by Upload' operation, it allows users to send files by uploading them directly to WhatsApp chats. This is useful for automating the sending of documents, images, or other file types to contacts or groups via WhatsApp, enhancing communication workflows.

Use Case Examples

1. Automate sending invoices or contracts as PDF files to clients via WhatsApp.
2. Send promotional images or brochures to customer groups automatically.
3. Share important documents with team members in a WhatsApp group without manual intervention.
