Help with apiKey login

I’m pretty new to google apis, and am not sure if this is an error or I’m doing something wrong (It’s probably my fault). I’m trying to get a simple API test working on my node server. This is what I have:

var google = require('googleapis');
google.options({ auth: '...myApiKey...' });
var androidpublisher = google.androidpublisher('v2');

app.get("/test3", function(req, res){
    //test googe apis
    var apiKey = "...myApiKey...";

    androidpublisher.edits.get({ editId: 1, packageName: "com.web2apptests"}, function(err, data){
        if(err){
            console.log("err:" + err);
            res.end("Look at the console.");
        }else{
            console.log(data);
            res.end("Look at the console.");
        }
    });
});

But I get the error: “Error: Login Required” I even tried with this line of code:

androidpublisher.edits.get({ auth: apiKey, editId: 1, packageName: "com.web2apptests"}, function(err, data){

What am I doing wrong? Is it possible to use androidpublisher with apiKey or does it have to be OAuth? Maybe I’m using the wrong key…

I was clicking around a bit. Creating service accounts, adding permissions, downloading keys and in the end I ended up with the same settings as before (i think), but this time it’s working, in response I get the ID and expiry time with this code:

app.get("/test3", function(req, res){
    var key = require(__dirname + "/keys.json");
    var jwtClient = new google.auth.JWT(key.client_email, null, key.private_key, ['https://www.googleapis.com/auth/androidpublisher'], null);
    jwtClient.authorize(function(err, tokens) {
        if (err) {
            console.log(err);
            res.end("Look at the console");
            return;
        }

        androidpublisher.edits.insert({ auth: jwtClient, packageName: "com.myproject"}, function(err, resp){
            console.log(err);
            console.log(resp);
            res.end("Look at the console");
        });
    });
});
