Is there a way to get all the versions of documents given a document ID , assume

@rajashekarv AFAIK, I believe there isn't a OOTB or Shared Component functionality for doing this. You may take a look at the 'ContentService' Interface in API and implement a function for doing so.

But let's also see what other practitioners or Appian core team opines on this.

If your intention is to download the document by surfacing the links, you could write a rule which creates a link to the specific version by making use of the document id, and this mechanism is more or less similar to the way we access the previous versions of document in portal designer interface.

If your intention is to get the document itself then afaik you may need to opt for writing a custom function as said above.
