Regarding FDM-1963 (Custom Attribute Retrieval and/or Updating)

[michael.reuter]

To whom it may concern:

We are trying to retrieve & possibly update custom attributes via API. Is there currently any functionality within Forge to allow us to do this?

According to the documentation here, the example shows that you can get information on standard metadata properties, but it does not mention custom properties. 

Is there currently a way to access custom file metadata properties via Forge?

Please also reference the response to this question at reference ## FDM-1963 on Stack Overflow

I want to know it too. Any API?

Thank you for the support by Xiao Dong. We are able to update the custom data fields successfully by the custom-attributes:batch-update API.
