Building REST endpoint programmatically from sharepoint url

Hi All,

I need to build REST endpoints programmatically from given Sharepoint Urls. Sample sharepoint url is as follows

Sharepoint URL:

https://mnp.sharepoint.com/_layouts/15/start.aspx#/Shared%20Documents/Forms/AllItems.aspx?RootFolder=%2FShared%20Documents%2FSubfolder01&FolderCTID=0x0120009F44C4A1ABF12A45B6B6D99BD0D16A0F&View=%7B60704400%2DA52F%2D41A8%2DB56B%2DF45A3FDC4AAE%7D
