Overview

This node allows updating a contact's information in the WhatsApp phone book via the Wappfy API. It is useful when you want to programmatically modify contact details such as first and last names stored in WhatsApp, for example, to keep your contact list synchronized with an external CRM or database.

Practical examples include:

  • Automatically updating a contact's name after receiving new data from a customer management system.
  • Correcting or standardizing contact names in bulk through automated workflows.
  • Enriching contacts with additional name details before sending personalized messages.

Properties

Name Meaning
Contact ID The unique identifier or phone number of the contact to update.
First Name The new first name to assign to the contact.
Last Name The new last name to assign to the contact (optional).

Output

The node outputs the JSON response returned by the Wappfy API after attempting to update the contact. This typically includes confirmation of the update or details about the updated contact.

The output structure is:

{
  "json": {
    // API response object with updated contact details or status
  }
}

No binary data is produced by this operation.

Dependencies

  • Requires an active Wappfy API credential configured in n8n, including:

    • Base URL of the Wappfy API instance.
    • Instance name.
    • API key for authentication.

  • The node makes HTTP requests to the Wappfy API endpoints to perform the update.

Troubleshooting

  • Common issues:

    • Invalid or missing Contact ID: Ensure the Contact ID or phone number is correct and exists in the WhatsApp phone book.
    • Authentication errors: Verify that the API key and other credentials are correctly set up.
    • Network or connectivity problems: Confirm that the Wappfy API base URL is reachable from the n8n environment.

  • Error messages:

    • Errors returned from the API will be included in the node output if "Continue On Fail" is enabled.
    • Typical error messages may indicate invalid parameters, unauthorized access, or resource not found.

  • Resolution tips:

    • Double-check input property values for correctness.
    • Re-authenticate or update API credentials if authorization fails.
    • Review API documentation for required permissions and parameter formats.
