Using HTTP API, there is any endpoint to delete the files from Deleted files folder(Dropbox Recycle bin)?
Yes, this would be the /2/files/permanently_delete endpoint, to permanently delete deleted files. Note that this requires the 'files.permanent_delete' scope which is only available to team-linked apps.
@Greg-DB for a personal account? there are such endpoints?
@SandeepCNT No, there isn't an endpoint like that available for non-team accounts, but I'll pass this along as a feature request. I can't promise if or when that might be implemented though.
To implement the features to get the deleted file list only, need to use this "/2/files/list_folder"endpoint, right?
Other than that I didn't find any such endpoint to get the deleted files list.
Yes, to list deleted items you'd need to use /2/files/list_folder[/continue] with include_deleted:true.
