Overview
This node interacts with the OpenProject API to retrieve details about a specific category by its ID. It is useful when you want to fetch information about a particular category within an OpenProject instance, such as for reporting, automation, or integration purposes.
A practical example would be automating project management workflows where you need to pull category details dynamically based on user input or other triggers.
Properties
| Name | Meaning |
|---|---|
| Id | The unique identifier of the category to view. Must be a number. |
Output
The node outputs JSON data representing the details of the requested category. This typically includes fields such as the category's name, description, and any other metadata provided by the OpenProject API for that category.
No binary data output is expected from this operation.
Dependencies
- Requires an API key credential to authenticate with the OpenProject API.
- The node configuration must include the base URL of the OpenProject instance.
- The node uses standard HTTP headers to request and accept JSON data.
Troubleshooting
- Common issue: Invalid or missing category ID will result in an error or empty response. Ensure the "Id" property is set correctly and corresponds to an existing category.
- Authentication errors: If the API key or base URL is incorrect or missing, the node will fail to connect. Verify credentials and endpoint settings.
- API rate limits or connectivity issues: Network problems or API restrictions may cause failures; check network access and API usage policies.
