Overview

This node integrates with Green API to enable enhanced WhatsApp automation, specifically supporting operations related to messages, groups, chats, and contacts. For the 'Message' resource and 'Send File by URL' operation, it allows users to send a file to a WhatsApp contact or group by providing a URL to the file. This is useful for automating the distribution of documents, images, or other media hosted online without needing to upload the file directly.

Use Case Examples

1. Automatically send promotional brochures hosted on a website to customers via WhatsApp.
2. Distribute event flyers or images by sending file URLs to WhatsApp groups.
3. Send important documents stored on cloud storage to contacts by URL.

Output

JSON

• result - The result of the send file by URL operation, typically including message status and metadata.

Dependencies

• Requires Green API credentials including an instance ID and API token for authentication.

Troubleshooting

• Common issues include invalid or inaccessible file URLs, which will cause the send operation to fail. Ensure the URL is publicly accessible and points directly to a file.
• Authentication errors may occur if the Green API credentials (instance ID or API token) are incorrect or expired. Verify credentials in the node settings.
• Network or API rate limits might cause temporary failures; retry logic or error handling is recommended.
• Error messages from the node will specify the resource and operation where the failure occurred, aiding in troubleshooting.
