Wappfy

Overview

This node integrates with the Wappfy API to interact with WhatsApp functionalities programmatically. Specifically, for the Profile resource and the Set Picture operation, it allows users to update their WhatsApp profile picture by providing a URL to the desired image file.

Common scenarios where this node is beneficial include:

• Automatically updating a WhatsApp profile picture based on external triggers or events (e.g., changing profile pictures daily or in response to marketing campaigns).
• Synchronizing user profile images across multiple platforms.
• Managing WhatsApp profiles in bulk via automation workflows.

Example: A marketing team could use this node to update the WhatsApp profile picture of a business account to reflect current promotions by supplying a URL to the promotional image.

Properties

Output

The node outputs the JSON response returned by the Wappfy API after attempting to set the profile picture. This typically includes confirmation details or error messages from the API.

The output structure is:

{
  "json": {
    // API response data confirming success or failure
  }
}

No binary data output is involved in this operation.

Dependencies

• Requires an active Wappfy API credential with a valid API key and instance name configured in n8n.
• The node makes HTTP requests to the Wappfy API endpoints.
• The provided File URL must be accessible by the Wappfy service (publicly reachable or properly authenticated if needed).

Troubleshooting

• Invalid or inaccessible File URL: If the URL is incorrect or the image cannot be fetched by the API, the operation will fail. Ensure the URL is correct and publicly accessible.
• Authentication errors: Missing or invalid API key or instance name will cause authentication failures. Verify credentials are correctly set up.
• API errors: The Wappfy API may return errors if the image format is unsupported or if there are rate limits. Check the API response message for details.
• Network issues: Connectivity problems between n8n and the Wappfy API endpoint can cause request failures.

To resolve errors:

• Double-check the File URL.
• Confirm API credentials are valid.
• Review API documentation for supported image formats and size limits.
• Enable "Continue On Fail" in the node settings to handle errors gracefully in workflows.
