Evolution API

Overview

The node "Evolution API" provides an interface to interact with the Evolution API, specifically supporting operations on various resources. For the Group resource and the Leave Group operation, this node allows a user to leave a specified group by providing the group ID. This is useful in scenarios where automated workflows need to manage group memberships dynamically, such as removing a bot or user from a chat group when certain conditions are met.

Practical example: Automatically leaving a group after completing a task or when a user unsubscribes from notifications.

Properties

Output

The output of the node is a JSON array containing the response from the Evolution API after attempting to leave the specified group. The exact structure depends on the API's response but typically includes confirmation of the action or error details if the operation failed.

No binary data output is indicated.
