Calling multiple API endpoints using Nodejs in a synchronous method

I am trying to make a call to four API endpoints using Nodejs in a synchronous method. I have seen (and tried!) many modifications of examples on stack overflow where this can be done using Promises and 'async'. But, the problem that I am having is that I specifically need the endpoint to retrieve a value to me before I call the next API so that I can concatenate that returned value into my next API call.

Here is the code I am working on:

 var STATE = 'Kansas';
 var OCCUPATION_NAME = 'Farmers';

getReq('http://api.dol.gov/V1/Statistics/OES/OE_AREA/?KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX&$filter=AREA_NAME eq ' + STATE).then(function(body1){

var options = {
    host: 'api.dol.gov',
    path: encode,
    type: 'GET',
    dataType: 'json',
    headers: {'accept' : 'application/json'}
};
var x = http.request(options,function(res){
console.log("Connected");
var str = '';
res.on('data', function(chunk) {
    str += chunk;
});
res.on('data',function(data){
    if(res.statusCode == 200){
        try{
            var data = JSON.parse(str);
            var state = data.d[0].AREA_CODE;
            array.push(state);
            console.log(state);
        }catch(e){
            console.log('Error parsing JSON');
        }
    }
    //console.log(data.toString());
});
});
x.end();
    return getReq('http://api.dol.gov/V1/Statistics/OES/OE_OCCUPATION/?KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX&$filter=OCCUPATION_NAME eq ' + OCCUP);
}).then(function(body2){
var options = {
    host: 'api.dol.gov',
    path: encode,
    type: 'GET',
    dataType: 'json',
    headers: {'accept' : 'application/json'}
};
var x = http.request(options,function(res){
 var str = '';
res.on('data', function(chunk) {
    str += chunk;
});
res.on('data',function(data){
    if(res.statusCode == 200){
        try{
            var data = JSON.parse(str);
            var occupationNum = data.d.results[0].OCCUPATION_CODE;
            array.push(occupationNum);
            console.log(occupationNum);
        }catch(e){
            console.log('Error parsing JSON');
        }
    }
});
});
x.end();
    return getReq('http://api.dol.gov/V1/Statistics/OES/OE_SERIES/?KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX&$filter=(OCCUPATION_CODE eq ' + "'" + occupationNum +  "'" + ') and (AREA_CODE eq ' + "'" + areaCode + "'" + ')');
}).then(function(body3){
    var options = {
    host: 'api.dol.gov',
    path: encode,
    type: 'GET',
    dataType: 'json',
    headers: {'accept' : 'application/json'}
};
var x = http.request(options,function(res){
console.log("Connected");
 var str = '';
res.on('data', function(chunk) {
    str += chunk;
});
res.on('data',function(data){
    if(res.statusCode == 200){
        try{
             var dataA = JSON.parse(str);
            //run a for loop 
            for(var i = 0; i < dataA.d.length; i++){
                var seriesNum = dataA.d[i].SERIES_ID;
                array.push(seriesNum);
                console.log(seriesNum);
            }
             //end for
        }catch(e){
            //console.log('Error parsing JSON');
        }
    }
});
});
x.end();
});

Notice how in my last endpoint call, it takes in the results from my first and second endpoint calls. Any help would be appreciated.
