Overview
This node allows managing WhatsApp groups using the Wuzapi API. It supports a variety of group-related operations such as creating groups, retrieving group information, managing participants, setting group descriptions, and more. This node is useful for automating WhatsApp group administration tasks within workflows, such as updating group topics, adding or removing members, or changing group settings programmatically.
For example, you can use this node to:
- Set or update the description/topic of a WhatsApp group.
- Add or remove participants from a group automatically based on external triggers.
- Retrieve invite links to share with new members.
- Change group names or photos without manual intervention.
Properties
| Name | Meaning |
|---|---|
| Group JID | The unique identifier (JID) of the WhatsApp group, e.g., 120363312246943103@g.us. |
| Description | The new description or topic text to set for the group, e.g., "Welcome to our group!". |
Output
The node outputs JSON data representing the response from the Wuzapi API for the performed operation. For the "Set Description" operation, the output typically contains confirmation details about the updated group description.
No binary data output is produced by this operation.
Dependencies
- Requires an active connection to the Wuzapi API via an API key credential configured in n8n.
- The node depends on helper functions for phone number validation and media preparation provided by the bundled GenericFunctions module.
- Proper network access to the Wuzapi API endpoints is necessary.
Troubleshooting
- Missing or invalid Group JID: Ensure the Group JID is correctly specified and corresponds to an existing WhatsApp group.
- API request failures: Network issues or invalid API credentials can cause errors. Verify API key validity and connectivity.
- Invalid description input: The description must be a non-empty string; empty or malformed inputs may cause the API to reject the request.
- Continue On Fail: If enabled, the node will continue processing other items even if one fails, returning error messages in the output JSON.
Common error message example:
"Binary property \"data\" not found"— This does not apply to the "Set Description" operation but indicates missing binary data when uploading images.
