Wappfy

Overview

This node interacts with WhatsApp groups via the Wappfy API, specifically enabling you to retrieve the list of participants in a specified WhatsApp group. It is useful when you need to programmatically access group membership details for automation, reporting, or integration purposes.

Common scenarios:

• Fetching all members of a WhatsApp group to synchronize with an external CRM or database.
• Auditing group participants for compliance or moderation.
• Triggering workflows based on group membership changes.

Practical example:
You have a WhatsApp group for customer support and want to regularly export the list of active participants to your support dashboard. Using this node operation, you can get the current participants and update your system automatically.

Properties

Output

The output is a JSON array where each item represents a participant in the specified WhatsApp group. Each participant object typically contains details such as their WhatsApp ID and possibly other metadata provided by the Wappfy API.

Example output structure (simplified):

[
  {
    "id": "1234567890@c.us",
    "isAdmin": true,
    "isSuperAdmin": false,
    "displayName": "John Doe"
  },
  {
    "id": "0987654321@c.us",
    "isAdmin": false,
    "isSuperAdmin": false,
    "displayName": "Jane Smith"
  }
]

If the node supports binary data output for this operation, it would be related to media files associated with participants, but for "Get Participants" operation, only JSON data is returned.

Dependencies

• Requires a valid connection to the Wappfy API service.
• An API key credential must be configured in n8n to authenticate requests.
• The node uses the base URL and instance name from the credentials to construct API calls.

Troubleshooting

• Common issues:

  • Invalid or missing Group ID: Ensure the Group ID is correct and corresponds to an existing WhatsApp group.
  • Authentication errors: Verify that the API key credential is correctly set up and has necessary permissions.
  • Network or API downtime: Check connectivity to the Wappfy API endpoint.

• Error messages:

  • "404 Not Found": The specified group does not exist or the Group ID is incorrect.
  • "401 Unauthorized" or "403 Forbidden": API key is invalid or lacks permission.
  • "500 Internal Server Error": Temporary server issue; retry after some time.

• Resolution tips:

  • Double-check the Group ID format and value.
  • Confirm API credentials and permissions.
  • Review API status or contact Wappfy support if persistent server errors occur.
