    <p>I don't know the API (mailchimp) you're using, so the solution might be totally wrong. But generally you can see the difference between synchronous and asynchronous programming. Please read some tutorials to fully understand the Node.js way, because it takes some time to embrace this kind of programming :-)</p> <p>The most important thing is that functions typically don't return values, but call a callback-function (sometimes not named <code>callback</code> but <code>done</code>) when they are ready or an error was encountered.</p> <pre><code>function signUp(name, email, callback) { // &lt;----- provide a callback var MailChimpAPI = require('mailchimp').MailChimpAPI; var API_KEY = 'asdfasdf', LIST_ID = 'asdfasdfas'; var api = new MailChimpAPI(API_KEY, { version: '1.3', secure: false }); var names = name.split(' '), status; var data = { apikey: API_KEY, id: LIST_ID, email_address: email, merge_vars: {'FNAME': names[0], 'LNAME': names[1]}, double_optin: false, send_welcome: true }; api.listSubscribe(data, function (error, result) { if (error) { console.log(error); callback(error); // &lt;--- this is one of the "exit"-points of the function } else { console.log('success'); callback(null, result); // &lt;--- this is another } }); // &lt;----------- no return! nobody cares about the return value. } exports.send = function (req, res, next) { var name = req.query.name, email = req.query.email; res.writeHead(200, {"Content-Type": "json"}); signUp(name, email, function (err, result) { // this function gets called when signUp is done (maybe seconds later) if (err) { res.send(500); return; } // don't know what the result looks like res.send({status: 'success'}); // res.end(); DON'T USE res.end() in express! }); }; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
