Query a point Rest service passing an X/Y position

[GustafsonTerry]

Greetings,

Seems like this should be a simple task but maybe its not possible.  I have a Mile Post service and I want to pass a single point geometry to it and have it return the nearest Miles Post.  This is the service I'm querying.  https://app.mdt.mt.gov/arcgis/rest/services/ALTIS/ALTIS_API/MapServer/1/query

I'm setting the where clause to the route id which is ROUTE_ID = 'C000021A'

I have attached an image of the other parameters being passed.  The problem is that the service just returns all of the Mile Posts for that route.  Is it possible to pass a point and get the nearest Mile Post for that route from this service?

Thanks,

Terry

So my input geometry was not formatted right.  It simply needed to be.
