Overview

This node allows you to update group settings via the Evolution API. It is designed for scenarios where you need to programmatically manage WhatsApp group configurations, such as restricting who can send messages or edit group information. Typical use cases include automating group moderation, enforcing communication policies, or integrating group management into larger workflows.

Practical examples:

  • Automatically set a group so only admins can send messages during important announcements.
  • Revert group settings to allow all members to participate after an event.
  • Lock group info editing to prevent unwanted changes.

Properties

Display Name Type Description
Nome Da Instância String Digite o nome da instância (Enter the instance name).
ID Do Grupo String ID do grupo para atualizar as configurações (Group ID to update).
Ação Options Configuração a ser aplicada no grupo (Setting to apply to group):
- Somente Admins Enviam Mensagens (Only admins send messages)
- Todos Enviam Mensagens (Everyone sends messages)
- Somente Admins Editam Configurações (Only admins edit settings)
- Todos Editam Configurações (Everyone edits settings)

All properties are required.

Output

The output is a JSON object (or array of objects) containing the result of the group settings update operation. The exact structure depends on the Evolution API's response, but typically includes fields indicating success, status, and possibly updated group details.

Example output:

[
  {
    "success": true,
    "message": "Configuração atualizada com sucesso",
    "groupJid": "123456789@g.us",
    "appliedAction": "announcement"
  }
]

Note: Actual fields may vary depending on the API response.

  • n8n Configuration: No additional configuration beyond credentials is required.

Troubleshooting

Common issues:

  • Invalid Credentials: If your API key or credentials are incorrect, the node will fail to authenticate.

  • Unsupported Operation: If you select an unsupported resource or operation, you may see an error like:

    Operação não suportada.
A função "update-settings" para o recurso "groups-api" não é suportada!

    Resolution: Double-check that you have selected the correct resource and operation.

  • Missing Required Fields: All input properties are required. Omitting any will result in validation errors.

  • Group Not Found: If the provided Group ID (ID Do Grupo) does not exist, the API may return an error indicating the group was not found.
