WaAPIInstall

Overview

This node interacts with the WaAPI API to retrieve a QR code associated with a specific client instance. It is useful in scenarios where you need to programmatically obtain the QR code for a client session, such as automating login or authentication processes that require scanning a QR code.

For example, if you are managing multiple client sessions and want to fetch their QR codes to display them on a dashboard or send them via email, this node can automate that retrieval.

Properties

Output

The node outputs JSON data containing the QR code information related to the specified client instance. This typically includes the QR code image or data string that can be used to render or process the QR code further.

If the node supports binary data output (not explicitly shown in the provided code), it would represent the QR code image in binary form suitable for direct use or download.

Dependencies

• Requires an API key credential for authenticating with the WaAPI service.
• The node communicates with the WaAPI endpoint at https://waapi.app/api/v1.
• No additional environment variables or external dependencies are indicated.

Troubleshooting

• Missing or invalid Id: Ensure the "Id" property is provided and corresponds to a valid client instance. An incorrect or missing Id will likely cause the API call to fail.
• Authentication errors: Verify that the API key credential is correctly configured and has the necessary permissions.
• Network issues: Confirm that the n8n instance can reach the WaAPI endpoint without firewall or proxy restrictions.
• Unexpected API responses: Check the API documentation or logs for any changes in the endpoint or response format.
