Overview

The node "Evolution API" provides an interface to interact with the Evolution API service. Specifically, for the Resource "Grupo" and Operation "Encontrar Participantes" (Find Participants), it allows users to retrieve the list of participants in a specified group. This is useful in scenarios where you need to manage or analyze group membership dynamically, such as monitoring active members, sending targeted messages, or syncing group data with other systems.

Practical examples include:

  • Fetching all participants of a chat group to display or process their information.
  • Automating workflows that depend on group membership changes.
  • Integrating group participant data into CRM or communication platforms.

Properties

Name Meaning
Nome Da Instância The name of the instance to connect to the Evolution API service.
ID Do Grupo The unique identifier (ID) of the group whose participants you want to find.

Output

The node outputs a JSON array containing the participants found in the specified group. Each item in the array represents a participant's data as returned by the Evolution API. The exact structure depends on the API response but typically includes participant identifiers and related metadata.

No binary data output is indicated.

Dependencies

  • Requires an API key credential to authenticate requests to the Evolution API.
  • The node expects the user to configure this credential within n8n before use.
  • Network access to the Evolution API endpoint is necessary.

Troubleshooting

  • Operation Not Supported Error: If you receive an error stating the operation is not supported, verify that the resource and operation names are correctly set to "groups-api" and "find-participants" respectively.
  • Missing Required Parameters: Ensure both "Nome Da Instância" and "ID Do Grupo" are provided; missing these will cause the node to fail.
  • Authentication Issues: Confirm that the API key credential is valid and has the necessary permissions.
  • API Connectivity Problems: Check network connectivity and API endpoint availability if requests time out or fail.
