You can browse through the web interface and then grab the URL from the address bar - however you may need to remove some parts to make it the correct format.
For example, the following was in my address bar: https://danmundy.sharepoint.com/Shared%20Documents/Forms/AllItems.aspx
I changed it to https://danmundy.sharepoint.com/Shared%20Documents/
