Full Rich text retrieval

Hi, I know that getDocument function with format “md” allows to retrieve markdown content of a document (like a rich text description of a task), but some formats are not retrieved, those not compatibile with markdown, like underline, font background color, callout.
How to retrieve the content of a document with ALL formats? For synchronization purpose with external app, this is a problem since those non-markdown formats are deleted when syncing back to Fibery.
Thanks

Giuse

Try ‘html’ instead
