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'
});

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'
};

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.
