How to create a link to waze meetup with web backup?

Question

I want to send a link to the website users to go to the Waze location. I am using a URL like this:

http://waze.to/?ll=9.9397690,-84.1442870&navigate=yes

And this works very well, but the problem is that when the user did not install Waze, the browser simply displays an error saying that it could not process this URL.

However, Waze can provide links with some kind of backup to its website, and it looks like this:

http://mobile-web.world.waze.com/en_GB/meetup/location?h=d1u0rvny3

But it uses a single argument hinstead of latitude and longitude. So, how can I generate (on a web server) a link with the location given by this argument h(e.g. second)?
