This workflow demonstrates how to build and send multipart/form-data request bodies using the Multipart Form-Data Builder component.
A loop is included to show how multiple requests can be generated by grouping on a unique key, with each key resulting in one request body.
The table input is preconfigured with file names that are resolved via the connected Workflow Data Area Connector node.
The parent folder is provided implicitly through the file system connection, allowing the workflow to run out of the box without knime:// links.
You can replace the file names with your own values and connect a different file system (for example, Local File System or Mountpoint) depending on where your files are stored.
