API built in express responds with empty array

I have my application populating an array with names. I can log the array values and it is getting the values, but using postman to make a request on localhost:8888/api/messages my response says matches : [] with the empty array. Why is my array empty in the response if I do indeed populate it?

router.get('/messages', function(request, res) {

  var names = [];
  ctxioClient.accounts(ID).contacts().get({limit:250, sort_by: "count", sort_order: "desc"}, 
    function ( err, response) {
      if(err) throw err;

      console.log("getting responses...");
      var contacts = response.body;
      var matches = contacts.matches;


      for (var i = 0; i < matches.length; i++){
        names.push(matches[i].name);
        matches[i].email;
      }  

    res.json({matches : names});   
  });


});

This is because the response.json() executes before the ctxioclient.get() happens. Call response.json inside .get() instead. Something like this

router.get('/messages', function(request, response) { // <--- router response
  var names = [];
  ctxioClient.accounts(ID).contacts().get({ limit: 250,sort_by: "count",sort_order: "desc"},function(err, resp) { // <---- using resp
      if (err) throw err;
      console.log("getting responses...");
      var contacts = response.body; 
      var matches = contacts.matches;
      for (var i = 0; i < matches.length; i++) {
        names.push(matches[i].name);
        matches[i].email;
      }
      response.json({ matches: names }); // <--- router response
    });
});
