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 by providing the group ID and instance name. 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 participant data with other systems.
Practical examples include:
- Fetching all participants of a WhatsApp group to send notifications.
- Auditing group membership for compliance or reporting.
- Integrating group participant data into CRM or marketing platforms.
Properties
| Name | Meaning |
|---|---|
| Nome Da Instância | The name of the instance where the group exists; used to identify the specific environment or account. |
| ID Do Grupo | The unique identifier 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 with their relevant details as returned by the Evolution API. The exact structure depends on the API response but typically includes participant identifiers and possibly metadata like names or roles.
No binary data output is indicated for this operation.
Dependencies
- Requires an API key credential for authenticating with the Evolution API.
- The node expects the Evolution API base URL and headers to be configured internally.
- No additional external dependencies are indicated beyond the Evolution API service.
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 request to fail.
- Authentication Issues: Confirm that the API key credential is valid and has the necessary permissions to access group participant data.
- Empty Participant List: If the output is empty, check if the group ID is correct and that the group actually contains participants.
