Overview
This node integrates with the NOD Marketplace API to retrieve information about product categories, products, and manufacturers. Specifically, the "Get Category" operation fetches detailed information about a single product category by its ID. This is useful when you want to enrich workflows with category metadata or validate category details before processing related products.
Practical examples:
- Fetching category details to display in an inventory management system.
- Validating category existence before assigning products to it.
- Automating updates or reports based on category attributes.

{
"id": "string",
"name": "string",
"description": "string",
"otherCategoryFields": "..."
}
No binary data is returned by this operation.
Dependencies
- Requires an API key credential for authenticating with the NOD Marketplace API.
- The node uses HMAC-SHA1 signing for request authentication.
- The base URL of the NOD Marketplace API must be configured in the credentials.
- Network access to the NOD Marketplace API endpoint is necessary.
Troubleshooting
- Invalid Category ID: If the category ID does not exist or is malformed, the API may return an error or empty response. Verify the ID is correct.
- Authentication Errors: Ensure that the API key credential is valid and has proper permissions.
- Network Issues: Check connectivity to the NOD Marketplace API endpoint.
- Unexpected Response Structure: If the API changes, the node might not parse the response correctly. Review API documentation for updates.
Common error messages:
"The operation getCategory is not supported!"— indicates an invalid operation parameter; ensure "Get Category" is selected.- HTTP 401 Unauthorized — check API credentials.
- HTTP 404 Not Found — likely invalid category ID.
