Overview
The node named "Evolution API" provides an interface to interact with the Evolution API service. Specifically, for the Resource "Group" and Operation "Find Participants," it fetches the list of participants in a specified group within an instance. This is useful in scenarios where you need to retrieve member information from a group, such as managing group communications, auditing group membership, or integrating group participant data into workflows.
For example, you might use this node to:
- Automatically gather all members of a chat group to send targeted notifications.
- Sync group participant lists with other systems like CRM or user management platforms.
- Monitor changes in group membership over time.
Properties
| Name | Meaning |
|---|---|
| Instance Name | The name of the Evolution API instance to connect to. |
| Group ID | The unique identifier (JID) of the group whose participants you want to retrieve. |
Output
The node outputs a JSON array containing the participants of the specified group. Each item in the array represents a participant with details as provided 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 for this operation.
Dependencies
- Requires an active connection to the Evolution API service.
- Needs an API authentication credential configured in n8n to authorize requests.
- The base URL for the API is set to
https://doc.evolution-api.com/api-reference. - No additional environment variables are explicitly required beyond the API credential.
Troubleshooting
- Operation not supported error: If you select an unsupported operation or resource, the node will throw an error stating the function is not supported. Ensure that "Group" resource and "Find Participants" operation are correctly selected.
- Missing or invalid credentials: The node requires valid API credentials; errors related to authentication indicate misconfiguration or expired tokens.
- Invalid Group ID or Instance Name: Providing incorrect or empty values for these required properties will cause the API call to fail. Double-check the inputs.
- Network or API errors: Connectivity issues or API downtime can cause failures. Verify network access and API status.
