AjaxInstall

Overview

This node, named "Ajax," is designed to interact with the Ajax API (version indicated in the code). It supports multiple resources and operations, including creating a Hub. The node facilitates sending requests to the Ajax backend to perform various actions such as managing hubs, users, devices, and more.

For the Create Hub operation under the Hub resource, the node allows users to create a new hub by providing necessary details like user ID, hub QR code, and optionally a hub name. This operation is useful in scenarios where you want to programmatically register or add new hubs into the Ajax system, for example, when automating device onboarding or integrating Ajax hubs into larger workflows.

Practical examples:

• Automatically creating a new hub when a new user signs up.
• Integrating Ajax hub creation into a device provisioning pipeline.
• Managing hubs dynamically based on external triggers or events.

Properties

Output

The node outputs JSON data representing the result of the Create Hub operation. This typically includes confirmation of the created hub's details such as its ID, status, and any metadata returned by the Ajax API.

If the node supports binary data output, it would relate to any files or media returned by the API, but for this operation, the primary output is structured JSON data confirming the hub creation.

Dependencies

• Requires an API key credential for authenticating with the Ajax API.
• Depends on the Ajax backend service being accessible.
• Uses internal helper classes for HTTP communication, state management, and response handling.
• No additional environment variables are explicitly required beyond the API authentication.

Troubleshooting

• Invalid or missing credentials: Ensure that the API key credential is correctly configured and has sufficient permissions.
• Incorrect Hub QR Code format: The hub QR code must follow the specified pattern (00000-00000-00000-00000). Invalid formats will likely cause errors.
• User Id not found or unauthorized: The provided user ID must exist and be authorized to create hubs.
• Network or API errors: Check connectivity to the Ajax API endpoint and verify that the service is operational.
• Missing required parameters: Both User Id and Hub Qr Code are mandatory; omitting them will cause validation errors.

Common error messages might include authentication failures, validation errors for input fields, or server-side errors from the Ajax API. Resolving these usually involves verifying inputs, credentials, and network access.
