Message → Send File By URL
AI-generatedOverview
This node operation sends a file to a specified WhatsApp chat using a file URL via the Green API. It allows users to specify the chat ID, the URL of the file to send, the file name, and an optional caption. This is useful for automating the sending of media files hosted online without needing to upload them manually. For example, sending an image or document link directly to a contact or group chat.
Use Case Examples
- Sending an image from a public URL to a WhatsApp group with a caption.
- Automating the delivery of PDF files to clients by sending the file URL to their chat ID.

| File Name | The name to assign to the file being sent. |

Output

Troubleshooting
- Ensure the file URL is accessible and publicly reachable; otherwise, the API call will fail.
- Verify that the chat ID is correctly formatted and corresponds to an existing chat.
- Check that the Green API credentials (instance ID and API token) are valid and have the necessary permissions.
- Common error messages include failures to send the file due to network issues or invalid parameters; the node error messages include the data sent for easier debugging.
