Do you really need to use the rest api manually? what is the developer using to build this application? If they use the ESRI JavaScript API, could they just use the Query() method? It takes a geometry as a spatial filter and handles all the details for you. Look at this example, it creates a buffer then uses the geometry to grab all census blocks in the buffer. you would get a parcel and select all fema zones in it.

I don't know why polygon doesn't work, but envelope should only have 4 points. xmin, ymin and xmax, ymax. Depending on how many FEMA areas you have, you could try to Point in Polygon them (the developer could run the query themselves and ignore the rest if it isn't working right.) Many ways to solve the same problem. I use this formula: //+ Jonas Raoni Soares Silva //@ http://jsfromhell.com/math/is-point-in-poly [rev. #0] function isPointInPoly(poly, pt){     for(var c = false, i = -1, l = poly.length, j = l - 1; ++i < l; j = i)         ((poly.y <= pt.y && pt.y < poly .y) || (poly .y <= pt.y && pt.y < poly.y))         && (pt.x < (poly .x - poly.x) * (pt.y - poly.y) / (poly .y - poly.y) + poly.x)         && (c = !c);     return c; } My poly is in a file and looks like this: var poly=[{x:35.1631035593,y:-106.659880001}, {x:35.1631035458,y:-106.659879999}, {x:35.1631035503,y:-106.659880015}, {x:35.1602168416,y:-106.679432832}, {x:35.1601067583,y:-106.679508129}, {x:35.1600635441,y:-106.679513221}, {x:35.1599856053,y:-106.679510715}, {x:35.1590417964,y:-106.680071918}, {x:35.1581326754,y:-106.680813656}, {x:35.1581325045,y:-106.681021692}, {x:35.1581325837,y:-106.681175784}, {x:35.1581326772,y:-106.681349715}, {x:35.1581324901,y:-106.681449898}] ...

The REST API docs are here: ArcGIS Server REST API Envelope is like this: geometryType=esriGeometryEnvelope&geometry={xmin: -104, ymin: 35.6, xmax: -94.32, ymax: 41} geometryType=esriGeometryEnvelope&geometry=-104,35.6,-94.32,41 Here is my working query: ... View more

JavaScript for sure. Then you can Use REST API via AJAX and hopefully, one day, WebSockets! ... View more

I will add that I have had an issue with this. I took the example from ESRI and changed the URL to my server and nothing. If I make it a L.esri.FeatureLayer and add the /0 - or whichever feature - to the end of the URL, it displays fine. I just figured our services were published differently. ... View more

You mention you can't use the HTML, so you have to take the JSON. What are you doing this in? I don't know why you would ever want the HTML response. Parsing all the HTML for the answer would be overly complicated. ... View more

It is a great library. I have got a lot of use out of it. Combine it with the ESRI REST API and you can make an AJAX call to add, delete, update ...! I started a class for it. function CRUD(url){  //url should look like: http://YourDomain/ArcGIS/rest/services/FeatName/FeatureServer/0          this.url=url;   }//end function CRUD CRUD.prototype={         add: function(addFeature){ ////needs to look like [{"geometry":{"x":-106,"y":35}, "attributes":{"name":"paul","number":123}}]   var addparams = "features="+addFeature+"&f=json";   var addurl=this.url+"/addFeatures";   alert(addFeature);   var http;   if (window.XMLHttpRequest){     http=new XMLHttpRequest();   }    else {   http=new ActiveXObject("Msxml2.XMLHTTP");     }   http.open("POST", addurl, true);   http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");   http.onreadystatechange = function() {//Call a function when the state changes.   if(http.readyState == 4 && http.status == 200) {   alert(http.responseText);   }   }   http.send(addparams);   }, //end ADD   update: function(updateFeature){   var updateparams = "features="+updateFeature+"&f=json";   var updateurl=this.url+"/updateFeatures";   var http;   if (window.XMLHttpRequest){     http=new XMLHttpRequest();   }    else {   http=new ActiveXObject("Msxml2.XMLHTTP");     }   http.open("POST", updateurl, true);   http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");   http.onreadystatechange = function() {//Call a function when the state changes.   if(http.readyState == 4 && http.status == 200) {   console.log(http.responseText);   }   }   http.send(updateparams);   }, //end UPDATE   delete: function(deleteFeature){  //takes objectid   var deleteparams = "objectIds="+deleteFeature+"&f=json";   var deleteurl=this.url+"/deleteFeatures";   var http;   if (window.XMLHttpRequest){     http=new XMLHttpRequest();   }   else {   http=new ActiveXObject("Msxml2.XMLHTTP");     }   http.open("POST", deleteurl, true);   http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");   http.onreadystatechange = function() {//Call a function when the state changes.   if(http.readyState == 4 && http.status == 200) {   console.log(http.responseText);   }   }   http.send(deleteparams);   }, //end DELETE   query: function(){   } // end QUERY };//end CRUD.prototype Throw it in a JS file and include a reference in your HTML. then use it like this: //USE CASE for DELETE and ADD var crud = new CRUD("http://Yourdomain/ArcGIS/rest/services/FeatName/FeatureServer/0");  //DELETE WORKS crud.delete(43); //ObjectID - you can get it using the vector layer onclick() and feature.properties.OBJECTID. //ADD WORKS - adding lines is easy just use leaflet toGeoJSON(); var pointToAdd='[{"geometry":{"x":-106.79192,"y":35.06148}, "attributes":{}}]'; crud.add(pointToAdd); //UPDATE WORKS var crud2 = new CRUD("http://YourDomain/ArcGIS/rest/services/featName/FeatureServer/0"); var feature='[{"geometry":{"x":-106.73975,"y":35.12765}, "attributes":{"OBJECTID":57,"name":"Paul","number":123}}]'; crud2.update(feature); ...

If Python didn't run in some funky sandbox, you could use Tkinter. Last time I checked, if you clicked a button, the GUI died. C# has a System.Diagnostics.Process.Start() which could possibly be used in your GUI to execute your scripts and pass parameters. It works fine on the desktop but I have never tried it in ArcMap. ...
