Overview
This node integrates with the Wuzapi API to manage WhatsApp groups. It supports a variety of group-related operations such as creating groups, joining via invite codes, retrieving group information, managing participants, and updating group settings like name, description, photo, and message permissions.
The Join operation specifically allows a user to join a WhatsApp group using an invite code or invite link. This is useful in automation workflows where you want to programmatically add the bot or user to a group without manual intervention.
Practical example:
- Automatically join a WhatsApp group when receiving an invite code from another system or user, enabling further automated messaging or monitoring within that group.
Properties
| Name | Meaning |
|---|---|
| Invite Code | The group invite code or full invite link used to join the WhatsApp group. Required. |
Output
The node outputs JSON data representing the response from the Wuzapi API for the join operation. This typically includes confirmation details about the group joined or any relevant metadata returned by the API.
No binary data output is produced by this operation.
Dependencies
- Requires an active connection to the Wuzapi API.
- Needs an API authentication credential configured in n8n (an API key or token).
- The node uses internal helper functions to validate phone numbers and prepare media data (not relevant for Join but part of the overall node).
Troubleshooting
- Common issues:
- Invalid or expired invite code/link: The API may reject the join request if the invite code is incorrect or no longer valid.
- Network or authentication errors: Ensure the API credentials are correctly set up and the Wuzapi service is reachable.
- Error messages:
"Binary property \"<name>\" not found"— Not applicable for Join operation but may appear in other operations involving images.- API error messages related to invalid invite codes should be checked and corrected by verifying the invite code format.
