Overview

This node allows you to join a WhatsApp group using the Wassenger WhatsApp API. It supports joining groups either by providing an invite code or an invite URL. This is useful for automating the process of adding a WhatsApp number (device) to a group, which can be part of workflows that manage group memberships dynamically.

Practical examples:

Automatically joining a support group when a new WhatsApp number is provisioned.
Adding a marketing WhatsApp number to a campaign group via an invite link.
Managing multiple WhatsApp devices and their group memberships programmatically.

Properties

Name	Meaning
WhatsApp Number	The ID of the WhatsApp number (device) that will join the group.
Join Method	Method used to join the group. Options: "Invite Code" or "Invite URL".
Invite Code	The invitation code for the group (required if Join Method is "Invite Code").
Invite URL	The invitation URL for the group (e.g., https://chat.whatsapp.com/XXXXXXX) (required if Join Method is "Invite URL").

Output

The output JSON contains the response from the Wassenger API after attempting to join the group. This typically includes confirmation details about the group joined or error information if the operation failed.

The node does not output binary data.

Dependencies

Requires an API key credential for the Wassenger WhatsApp API.
The node depends on the Wassenger service being accessible and properly configured with valid WhatsApp numbers/devices.
The "WhatsApp Number" property must correspond to a valid device registered in Wassenger.

Troubleshooting

Common issues:
- Invalid or expired invite codes or URLs will cause the join operation to fail.
- Using a WhatsApp number/device that is not registered or active in Wassenger will result in errors.
- Network or authentication failures with the Wassenger API may prevent joining groups.
Error messages:
- Errors returned from the API usually include descriptive messages such as "Invalid invite code" or "Device not found".
- If the node throws an error related to missing parameters, ensure the correct join method is selected and the corresponding invite code or URL is provided.
Resolution tips:
- Verify the invite code or URL is current and valid.
- Confirm the WhatsApp number/device exists and is active in your Wassenger account.
- Check API key credentials and network connectivity.
