Q:

How to replace the deprecated ScriptDb with Mongodb using URL Fetch service?

Due to the recent ScriptDb deprecation I need to replace it. I chose MongoDb(as I need noSQL db). Google does not provide any guides on how to connect mongo. It's just said that one should use mongolab and URL Fetch service.
I created a data base on mongolab. They gave me the following ways of connecting to it:
To connect using the shell:
   mongo ds045679.mongolab.com:45679/prjacc -u <dbuser> -p <dbpassword>
To connect using a driver via the standard URI (what's this?):
   mongodb://<dbuser>:<dbpassword>@ds045679.mongolab.com:45679/prjacc

But there's no driver for google script
so I can't figure out how to replace my old code:
var db = ScriptDb.getMyDb();
// work with db...

with access to mongo using URL Fetch Service. 
Any help is appreciated!

A:

It seems that I've found a solution.
MongoDB also provides the third way of accessing the DB, though they strongly recommend to use 2 ways described in my question. This is to use their REST API:

So it seems we should pass this url https://api.mongolab.com/api/1/databases?apiKey=<your-api-key> to the UrlFetchApp.fetch() function.
Please correct me if I'm not right. Any additions and notes are appreciated.
