Overview

This node interacts with the Wassenger WhatsApp API to manage WhatsApp groups. Specifically, the "Remove Participants" operation under the "Groups" resource allows users to remove one or more participants from a specified WhatsApp group associated with a particular WhatsApp number.

Common scenarios for this node include:

Managing group membership by removing inactive or unwanted participants.
Automating group moderation tasks in business communication channels.
Maintaining updated group lists by programmatically removing phone numbers.

For example, a customer support team might use this node to automatically remove users who have unsubscribed from a WhatsApp broadcast group.

Properties

Name	Meaning
WhatsApp Number	The ID of the WhatsApp number (device) from which the group is managed.
Group ID	The unique identifier of the WhatsApp group from which participants will be removed.
Phone Numbers	One or more phone numbers (in international format, e.g., +1234567890) to be removed from the group.

Output

The node outputs JSON data representing the result of the removal operation. This typically includes confirmation details about the participants removed or any relevant status messages returned by the Wassenger API.

No binary data output is indicated for this operation.

Dependencies

Requires an active connection to the Wassenger WhatsApp API.
Needs an API key credential configured in n8n for authentication with the Wassenger service.
The node depends on dynamic loading of available WhatsApp numbers ("devices") and groups for selection in the UI.

Troubleshooting

Common issues:
- Invalid or missing WhatsApp number or group ID can cause failures.
- Incorrectly formatted phone numbers may not be recognized by the API.
- Removing participants who are not members of the group may result in errors or no action.
- Network or authentication errors if the API key is invalid or connectivity is lost.
Error messages:
- Errors related to authorization usually indicate problems with the API key; verify and update credentials.
- "Group not found" or similar messages suggest the group ID is incorrect or the WhatsApp number does not have access to that group.
- Validation errors on phone numbers require checking the format and ensuring they exist in the group.

To resolve these, ensure all input parameters are correct, the API key is valid, and the target participants are indeed part of the group.
