Overview

The node interacts with the Wazzap API to perform various operations related to WhatsApp groups. Specifically, for the "👥 Group" resource and the "🔍 Fetch Participants" operation, it fetches the list of participants in a specified WhatsApp group. This is useful for scenarios where you need to retrieve group member information for analysis, reporting, or further automated messaging workflows.

Practical examples include:

  • Automatically retrieving all members of a WhatsApp group to send personalized messages.
  • Monitoring group membership changes by periodically fetching participant lists.
  • Integrating group participant data into CRM or marketing platforms.

Properties

Name Meaning
👥 Group ID (JID) The unique identifier of the WhatsApp group in JID format (e.g., 1234567890-123456@g.us).
📱 Recipient Phone Number The full phone number of the recipient including country code, used as context for the API call.
⚙️ Additional Options Optional settings to customize the request:
- 🔢 Priority Number Selects the sending number slot: 0 = Default, 999 = Random, 1–5 = Specific number slot.
- ⏱️ Delay Settings Configure a random delay range (in milliseconds) before sending messages, with start and end values.

Output

The node outputs a JSON array containing the fetched participants' data from the specified WhatsApp group. Each item in the array represents a participant with details as provided by the Wazzap API (such as participant ID, name, status, etc.).

If the node supports binary data output, it would typically relate to media or attachments associated with participants, but this operation focuses on participant metadata only.

Dependencies

  • Requires an active connection to the Wazzap API service.
  • Needs an API authentication token configured in n8n credentials to authorize requests.
  • The base URL for API requests is https://doc.wazzap.mx/api-reference.
  • No additional environment variables are explicitly required beyond standard API credential setup.

Troubleshooting

  • Unsupported operation error: If the node throws "Unsupported operation." it means the selected resource-operation combination is not implemented. Verify that "👥 Group" and "🔍 Fetch Participants" are correctly chosen.
  • Invalid Group ID or Recipient Number: Ensure the group JID and recipient phone number are correctly formatted and valid; otherwise, the API may return errors or empty results.
  • API Authentication Failures: Check that the API key or token is correctly set up in n8n credentials and has sufficient permissions.
  • Network Issues: Connectivity problems to the Wazzap API endpoint can cause timeouts or failures; verify network access and proxy settings if applicable.
