HighQ API - 403 Access Denied on Folder Metadata Update

Hi everyone,

I'm working on a HighQ implementation where I need to pass data from one iSheet to the "Folder metadata" iSheet when a new iSheet item is created. The Folder metadata iSheet has several custom columns that I intend to update via the API.

To achieve this, I'm using the PUT request:
/{version}/isheet/{isheetid}/items/{itemid}
to update the relevant columns. However, when I attempt either a PUT or GET request, I receive a 403 Access Denied error.

Context & Troubleshooting Steps:

  • I can create, view, edit, and delete folders within the web UI.
  • I can retrieve folder details using the GET request:
    /{version}/folders/{folderid}
  • I do not believe it's a permission issue, as I can perform all folder operations via the UI.
  • I tested creating a folder via the API, then attempted to access it—but I still get the 403 error when trying to update its metadata.

My Questions:

  1. Are there any specific API permissions or settings I might be missing?
  2. Do folder metadata iSheets require a different API approach for updates?
  3. Has anyone encountered this issue and found a solution?

Any insights or guidance would be greatly appreciated! Thanks in advance.
