Evolution API

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 auditing group composition.

Practical examples include:

• Fetching all participants of a chat group to send personalized notifications.
• Auditing group membership for compliance or moderation purposes.
• Integrating group participant data into other workflows or databases.

Properties

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 for authenticating with the Evolution API.
• The base URL for requests is set to https://doc.evolution-api.com/api-reference.
• Proper configuration of the API authentication credentials in n8n is necessary.

Troubleshooting

• Operation not supported error: If the node throws 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; otherwise, the API call will fail.
• Authentication errors: Confirm that the API key credential is valid and has sufficient permissions.
• Empty participant list: This might indicate the group ID is incorrect or the group has no participants.
