Answer 1

You use a Number in your query, but the particular gx_id seems to be of type String.

Enclose the Number with single-quotes:

https://www.googleapis.com/mapsengine/v1/tables/14538994882799551513-11853667273131550346/features?where=gx_id%3D%27900%27

Also, you don't have to worry about creating and keeping track of your ID's. the API says you need to include gx_id only to make sure that no Feature is sent twice. Therefore, you can just throw in a string representing your system's current time for example.
