Overview

This node operation downloads a file from the HumHub API by its ID and stores the file data in a specified binary property of the workflow item. It is useful for workflows that need to retrieve and process files stored in HumHub, such as downloading user-uploaded documents or media files for further automation or analysis.

Use Case Examples

1. Download a file by its ID and save it to the binary property 'data' for further processing in the workflow.
2. Automate file retrieval from HumHub to integrate with other systems or storage solutions.
