Overview
This node integrates with the Go WhatsApp Web MultiDevice API to manage WhatsApp groups programmatically. Specifically, the "Add Participant" operation under the "Group" resource allows users to add one or more participants to a specified WhatsApp group by their phone numbers.
Common scenarios for this node include automating group membership management in WhatsApp for communities, customer support groups, or team collaboration channels. For example, a business could automatically add new customers to a WhatsApp group after signup, or an event organizer could bulk-add attendees to a discussion group.
Properties
| Name | Meaning |
|---|---|
| Group ID | The unique identifier of the WhatsApp group where participants will be added. |
| Participant Phone | Comma-separated list of phone numbers representing the participant(s) to add to the group. |
Output
The node outputs JSON data representing the result of the add participant operation. This typically includes confirmation details such as success status and any relevant metadata returned by the Go WhatsApp API about the updated group or participants.
No binary data output is involved in this operation.
Dependencies
- Requires an active connection to the Go WhatsApp Web MultiDevice API.
- Needs an API authentication token or key configured via n8n credentials (referred generically as "an API key credential").
- The node expects the base URL of the API to be set in the credentials configuration.
Troubleshooting
Common issues:
- Invalid or missing Group ID can cause failures to locate the target group.
- Incorrectly formatted phone numbers or unsupported country codes may lead to participant addition errors.
- Network or authentication errors if the API key or host URL is misconfigured.
Error messages:
"Unknown resource: group"— indicates the resource parameter was not correctly set to "group".- API error responses related to invalid group or participant data will be surfaced; ensure all inputs are valid and properly formatted.
Resolution tips:
- Verify that the Group ID corresponds to an existing WhatsApp group accessible by the authenticated account.
- Ensure phone numbers are provided in the correct international format without extra characters.
- Confirm API credentials and host URL are correctly configured in n8n.
