JavaScript SDK

Suggest Edits

Overview

The Userback JavaScript SDK provides developers with powerful tools to seamlessly integrate Userback into your application, enabling precise control and customization of the widget and feedback collection.

Prerequisites

Before you begin, ensure the following:

  • Userback Workspace: A workspace is needed to collect and manage feedback.
  • Access Token: Retrieve your token via the Code Icon in your workspace.
  • Plan Requirements: Available on all plans; Custom Data Collection (setData() and custom_data) requires the Scale Plan or higher.

Why use the JavaScript SDK?

Powerful tools for developers to integrate Userback seamlessly into applications and do things like:

  • Identify Users: Associate feedback with individual users using identify() or user_data. Personalize insights with attributes like name, email, and account details.
  • Control the Widget: Use methods like show(), hide(), and destroy() to control widget visibility and behavior dynamically.
  • Trigger Widget Pop-ups: Open specific feedback forms or tools (e.g., screenshot, video) programmatically using open().
  • Survey Integration: Launch and close surveys on-demand with openSurvey() and closeSurvey().
  • Session Replay Management: Start, stop, and customize session replay to analyze user interactions in detail.
  • Track Custom Events: Add specific events to session replays with addCustomEvent() for detailed behavior analysis.
  • Dynamic Data Handling: Capture and attach session-specific (setData()) or static (custom_data) information for richer context.
    (Custom Data requires the Scale Plan or higher.)
  • Event Handling: Leverage hooks like on_load or before_send to trigger custom behaviors based on widget events.
  • Widget Customization: Modify appearance, position, triggers, and more using widget_settings. Adjust settings dynamically for precise control.
  • Environmental Adaptation: Optimize the widget for different environments (local vs. production) using options like is_live and native_screenshot.

SDK Methods

Identify Users

identify(uid: string, attributes: object)

Identifies a logged-in user with unique attributes. Should be used after initializing the widget. 

MyApp.on('login', () => {
  Userback.identify('USR789', {
    name: 'Jane Doe',
    email: '[email protected]',
    plan: 'Enterprise',
    account_id: '789XYZ'
  });
});

Note:

  • identify() can be called multiple times, and it overwrites previous data.
  • Key names should not contain special characters.
  • Values must be JSON strings, numbers, or booleans.

user_data: object

Use this when the JavaScript SDK hasn't been initialized. This will identify the user and provide a similar set of attributes.

Userback.user_data = {
  id: 'USR789',
  info: {
    name: 'Jane Doe',
    email: '[email protected]',
    plan: 'Enterprise',
    account_id: '789XYZ'
  }
};

Widget Button

show(), hide()

Show or hide the Userback widget button on the screen.

Userback.show(); // Show the widget
Userback.hide(); // Hide the widget

Widget Pop-up

open(type: string, destination: string)

Opens the widget for specified feedback type and destination. 💡 Tip: Hide the Widget Button with Widget Settings.

Feedback Types: general, bug, and feature_request

Destinations: screenshot, video, and form


Userback.open('bug', 'screenshot'); // open the screenshot tool and then direct to the bug form

close()

Closes the Userback widget popup. 

Userback.close();

Widget Destroy

destroy()

Removes the Userback widget and SDK from your application.

Userback.destroy();

Survey

openSurvey(survey_id: string)

Opens the specified survey. 💡 Tip: Hide the Survey with Survey Settings.


Userback.openSurvey('%%survey_id%%');

closeSurvey()

Closes the Userback survey.


Userback.closeSurvey();

Session Replay

startSessionReplay(options: object)

When session replay is turned off for your domain, you can still start it programmatically using startSessionReplay().


Userback.startSessionReplay({
    block_rule: '.userback-block', // optional
    ignore_rule: '.userback-ignore', // optional
    log_level: ['log', 'warn', 'info', 'debug', 'error'] // optional
    tags: ['tag1', 'tag2'] // optional
});

stopSessionReplay()

Stops full session replay.


Userback.stoptSessionReplay();

addCustomEvent(event_title, event_details)

Track event in session replay.


Userback.addCustomEvent('account_upgrade', {
    account_id: 123456 ,
    amount: '99'
});

SDK Options

Name and Email

Automatically populate Feedback name and email fields without relying on User Identification.

email: string

Set the default email. The email field will be auto-filled in the feedback form.

Userback.email = "[email protected]";

name: string

Set the default name. The name field will be auto-filled in the feedback form.

Userback.name = "Someone";

Categories and Priority

categories: string

Define the categories that can be chosen in the feedback form.

Userback.categories = "Frontend,Backend,Database,UI";

priority: string

Set the default priority level for feedback.

Priority Types: low, neutral, high, and urgent

Userback.priority = "urgent";

Use this when the JavaScript SDK hasn't been initialized. This will identify the user and provide a similar set of attributes.

Userback.user_data = {
  id: 'USR789',
  info: {
    name: 'Jane Doe',
    email: '[email protected]',
    plan: 'Enterprise',
    account_id: '789XYZ'
  }
};

Custom Data

setData(data: object)

Capture session-specific or dynamically changing data. Use this method after initializing the widget with init().

Userback.setData({
    AB_test_variant: 'B',
    time_on_page: '2m 15s'
});

🔑 Important: The setData() method is only available on the Scale Plan or higher.

Note:

  • setData() can be called multiple times, overwriting previous data.
  • Key names should not contain special characters.
  • Values must be JSON strings, numbers, or booleans.

custom_data: object

  • Capture static custom data when the JavaScript SDK hasn't been initialized.
Userback.custom_data = {
    page_name: 'Checkout',
    user_status: 'Active'
};

🔑 Important: The custom_data property is only available on the Scale Plan or higher.


Event Handling

on_load: function, on_open: function, on_close: function, before_send: function, after_send: function

Customize the widget's behavior during specific events.

Userback.on_load = () => {
  console.log("Widget Loaded");
};

Build Environment

is_live: boolean

Configure the screenshot engine based on your website's hosting environment.

  • is_live: true: Use this when your website is locally hosted, but assets like images and scripts are publicly accessible. Enables the live screenshot server for higher-quality captures.
  • is_live: false: Forces the use of the client-side screenshot engine, which may not generate pixel-perfect images. Recommended for restricted or isolated environments. Learn how to whitelist our IPs for improved quality.
Userback.is_live = true;

Native Screenshot

native_screenshot: boolean

Force the browser's built-in Screen Capture API for capturing screenshots.

Userback.native_screenshot = true

Note: Useful when dealing with complex web elements like shadow DOM and iframes. This enables pixel-perfect screenshots that may not be achievable using our default screenshot engine.

Widget Settings

widget_settings: object

Dynamically configure various aspects of your widget's appearance and functionality.
