Evolution API

Overview

The node "Evolution API" allows interaction with the Evolution API service. Specifically, for the Resource "Group" and Operation "Update Group Picture," it updates the profile picture of a specified group by setting a new image URL. This is useful in scenarios where group images need to be refreshed or changed dynamically, such as updating branding, event-specific images, or correcting outdated pictures.

Practical example: Automatically update a WhatsApp group picture when a marketing campaign starts by providing a new image URL.
