AvantGuard - HuduInstall

Overview

The "Get Relations" operation for the "Relations" resource in this custom n8n node is designed to retrieve a list of relations from an external service (presumably Hudu, as indicated by the node's name). This operation allows users to fetch paginated data about relations, with optional query parameters to control pagination.

Common Scenarios:

• Integrating Hudu relation data into automated workflows.
• Fetching and processing lists of relations for reporting or synchronization purposes.
• Building dashboards or triggers based on relation data.

Practical Example:
A user might use this node to periodically pull all relations from Hudu, process them, and update another system or send notifications when new relations are found.

Output

The node outputs a JSON object containing the retrieved relations. The structure typically includes:

• An array of relation objects, each representing a single relation.
• Pagination information if provided by the API (such as total count, current page, etc.).

Example output structure:

{
  "relations": [
    {
      // Relation fields (e.g., id, name, type, etc.)
    }
  ],
  "pagination": {
    "page": 1,
    "page_size": 20,
    "total": 100
  }
}

Note: The exact field names depend on the external API's response.

Dependencies

• External Service: Requires access to the Hudu API.
• API Key/Credentials: Needs valid credentials (avantguardHuduApi) configured in n8n.
• Environment Variable: The base URL for the API must be set in the credentials as baseUrl.

---

Troubleshooting

Common Issues:

• Invalid Credentials: If the API key or base URL is incorrect, authentication errors will occur.
• Missing Required Fields: Not providing necessary query parameters may result in incomplete or failed requests.
• Pagination Errors: Setting invalid values for "Page" or "Page Size" could lead to empty results or API errors.

Common Error Messages:

• "401 Unauthorized": Check your API credentials and base URL.
• "400 Bad Request": Ensure that query parameters like "Page" and "Page Size" are valid numbers.
• "404 Not Found": Verify the endpoint and resource exist in your Hudu instance.
