Complete Uazapi integration - Premium WhatsApp API with advanced messaging and automation

Overview

This node enables creating and managing WhatsApp groups via the Uazapi WhatsApp API. Specifically, the "Create Group" operation allows users to create a new WhatsApp group by specifying a group name and optionally adding participants at creation time.

Common scenarios where this node is beneficial include:

  • Automating the creation of WhatsApp groups for customer support or community engagement.
  • Quickly setting up groups with predefined members for team collaboration.
  • Integrating WhatsApp group management into broader automation workflows.

For example, a business could automatically create a group for a new project team and add relevant participants by their phone numbers, streamlining communication setup.

Properties

Name Meaning
Group Name The name to assign to the new WhatsApp group (required).
Participants Comma-separated list of phone numbers to add as initial group members (optional).
Additional Fields Optional extra settings:
• Reply to Message ID: ID of a message to reply to.
• Delay (seconds): Delay before sending messages.
• Disable Link Preview: Whether to disable link previews in messages.
• Mention Users: Comma-separated phone numbers to mention in messages.

Output

The node outputs a JSON object containing the response from the Uazapi API after attempting to create the group. This typically includes details about the newly created group such as its ID, name, participants, and status.

If an error occurs, the output JSON will contain an error field with the error message.

No binary data is produced by this operation.

Dependencies

  • Requires an active Uazapi WhatsApp API account with valid credentials including an API key, API token, instance ID, and API URL configured in n8n.
  • The node uses these credentials to authenticate requests to the Uazapi service.
  • No additional external dependencies are required beyond the configured API access.

Troubleshooting

  • Common issues:

    • Invalid or missing API credentials will cause authentication failures.
    • Incorrectly formatted phone numbers in the Participants field may result in errors or participants not being added.
    • Network connectivity problems can prevent successful API calls.
  • Error messages:

    • "Unknown resource: group" — indicates the resource parameter was set incorrectly; ensure it is exactly "group".
    • API errors returned from Uazapi will be included in the output's error field; check the message for details.
  • Resolutions:

    • Verify all credential fields are correctly set in n8n.
    • Ensure phone numbers include country codes and are comma-separated without extra spaces.
    • Check network connectivity and API endpoint accessibility.
