Overview

This node operation uploads a file to the Green API cloud storage for WhatsApp messaging. It supports uploading files either from binary data provided by a previous node or from a file path on the system. This is useful for scenarios where you want to programmatically upload media files to be used in WhatsApp messages, such as images, documents, or videos.

Use Case Examples

  1. Uploading a user-uploaded image from a previous node's binary data to Green API cloud storage.
  2. Uploading a document file from a specified file path on the system to Green API cloud storage for later sending via WhatsApp.
