AjaxInstall

Overview

The node named "Ajax" is designed to interact with an Ajax API, specifically version 1 as indicated in the description. It supports multiple resources and operations, including the "Camera" resource with an "Unlink Camera" operation. The primary function of this node is to perform API calls to manage various entities such as users, hubs, cameras, and more within the Ajax ecosystem.

For the "Unlink Camera" operation under the "Camera" resource, the node facilitates unlinking a specific camera from a hub for a given user. This can be useful in scenarios where a camera needs to be removed or reassigned, such as when decommissioning hardware, troubleshooting device issues, or managing access control.

Practical example:

• A security administrator wants to remove a camera from a particular hub because it is being replaced or relocated. Using this node, they provide the user ID, hub ID, and camera ID to unlink the camera efficiently via the Ajax API.

Properties

Output

The node outputs JSON data representing the result of the unlink operation. This typically includes confirmation of success or failure, and may contain details about the updated state of the camera or hub after unlinking.

If the node supports binary data output (not explicitly shown in the provided code), it would generally relate to any media or files associated with the camera, but this is not evident here.

Dependencies

• Requires an API key credential for authenticating with the Ajax API.
• Depends on the HttpClient class for making HTTP requests to the backend Ajax API.
• Utilizes internal modules for state management and operation resolution/execution.
• The node expects proper configuration of credentials within n8n to connect securely to the Ajax API.

Troubleshooting

• Common Issues:

  • Invalid or missing API credentials will cause authentication failures.
  • Providing incorrect or non-existent userId, hubId, or cameraId will likely result in errors or no action.
  • Network connectivity problems can prevent successful API calls.

• Error Messages:

  • Authentication errors: Ensure the API key credential is correctly set up and has necessary permissions.
  • Resource not found: Verify that the userId, hubId, and cameraId are correct and exist in the system.
  • Operation fallback errors: If the operation is not supported or fails, check if the API version matches the node's expectations.
