Answer 1

Hello Kyriakos Papadimos,

Thanks for reaching out. Updating the fields/columns (of type Managed metadata / taxonomy terms) of a list item in a SharePoint document library is not possible using Graph API. Please refer to the Graph API GitHub form page for more information: https://github.com/microsoftgraph/microsoft-graph-docs/issues/4911. I would suggest posting your query and feedback on the Graph Feedback Forum.

@Kyriakos Papadimos Suggest checking out this post https://stackoverflow.com/questions/55033458/cant-update-sharepoint-managed-meta-data-field-from-microsoft-graph-explorer

I was able to find the name field for my Managed Meta Data field and then populate via MSGraph. Using make.com and have three parts, upload document, api call to get ItemId using DriveId, api call to set my fields including managed meta data field.
I do know the value of GUID for my managed meta data value I need to set, so could be problematic if this is variable and you need to find it.
