How to fetch Webi document ID

Hi,

  I am new to Restful SDK and working on to refresh, export and save Webi reports in various formats. We have around 60 webi reports and we hit the restful URL  by passing document ID for each report. In the rebean framework, we used to pass the document name. But in the restful framework since we need to use the document ID, I would like to understand if there is a way to fetch the document ID by passing document name?

This is because we have multiple regions and since the document ID is not the same in all the regions, hard coding do not seem to work and also not a good practise.

Any Suggestions?

Thanks,
