When it comes to collecting feedback, understanding who your users are and how they interact with your product is crucial. By knowing who the feedback is coming from, you can gain valuable insights and make informed decisions.

One way to improve the accuracy and efficiency of the feedback process is to prefill fields and add custom data with information about the user, such as their name, email address, and account details. This not only saves time, but also enables you to respond to user feedback more quickly and effectively.

The JavaScript API is only available on certain plans. If you're unsure if you have access to this feature, check out this article or chat with Userback support team for more information.

Getting Started with User Identification

First check out the JavaScript API as there are two ways to use User Identification your users based on your installation method. With the user_data, you set user information before adding the JavaScript SDK, while identify lets you add or update user information after the SDK has loaded. The identify method gives you more control over user information, but you must first load the SDK.

Next, create a JavaScript object using one of the methods below that includes a unique identifier (uid), default attributes (name, email,), and custom attributes that provide additional information about the user, location, first seen, last seen are set automatically.

Method 1: user_data

Sets the user information before the JavaScript SDK is added. This saves time and streamlines the process, but you won't be able to add custom attributes or update user information after the SDK has loaded. Best used with a Basic Installation.

// Setting Userback Access Token
window.Userback = window.Userback || {};
Userback.access_token = '[YOUR_ACCESS_TOKEN]';

// Setting User Data with user_data
Userback.user_data = {
id: 123456,
info: {
name: 'Tony Stark',
email: '',
company: 'Stark Industries',
plan: 'Premium',
account_id: 456785

// Loading Userback Widget
(function(d) {
var s = d.createElement('script');
s.async = true;
s.src = '';
(d.head || d.body).appendChild(s);

Method 2: identify()

Allows you to add or update user information in real-time after the SDK has loaded. You can include custom attributes, but you need to make sure the SDK is loaded before you can use the identify() method. Best used with an Advanced Installation.

<script src=""></script>

// Initializing Widget & Setting Userback Access Token
Userback.init('[YOUR_ACCESS_TOKEN]', {
on_load: () => {
console.log('Widget Load Successful');

// Setting User Data with identify()
Userback.identify(123456, {
name: 'Tony Stark',
email: '',
company: 'Stark Industries',
plan: 'Premium',
account_id: 456785

What's important to know!

  • When a user submits feedback, their data is added or updated in Userback against all feedback they've submitted in the past so it's up to date.

  • The identify() method can be called multiple times with previous data overwritten.

  • Key names can’t contain periods ('.'), dollar signs ('$'), characters like ~`!@#%^&*'{}|\'". — If an unsupported character is used, the key will be created with an underscore.

  • Data values must be sent as JSON strings, numbers or booleans (true or false). We can’t accept object, nested hashes and array data formats.

Viewing User Identification data in Userback

Once you've successfully sent user data to Userback, you'll be able to view it in the right-hand panel of the Userback dashboard. This will allow you to see at a glance who has

provided feedback and access their information quickly and easily.
