Widget SDK

This repository contains a JS SDK and helpful documentation for building widgets for Ada.


[2.0.1] - 2021-04-12

This version contains breaking changes.

  • Security improvements around sending and receiving widget data
  • Inputs and metadata are no longer parsed from query parameters in the URL
  • Widget inputs are no longer included in <obj>.metaData, and are now found inside <obj>.widgetInputs
  • The language property, <obj>.metaData.lang has been renamed to <obj>.metaData.language

[1.0.1] - 2021-02-02

  • Widget constructor now takes appId as first argument, with _window being deferred to second
  • Widget initialization success and failures are now being logged to Datadog, before firing the "WIDGET_INTIALIZED" and "WIDGET_INITIALIZATION_FAILED" events respectively.

[1.0.0] - 2020-07-15

  • #init will now return the "WIDGET_INITIALIZED" event when the Widget is not in the "active" state. Previously, #init would return a "WIDGET_INITIALIZATION_FAILED" event.

Widget Setup

Initialize the Widget SDK on your page by calling widgetSDK.init and registering all required callbacks.

Importing the SDK

import AdaWidgetSDK from "@ada-support/ada-widget-sdk";
const widgetSDK = new AdaWidgetSDK();


Widget SDK Methods


Must be called before user data can be submitted.

Performs setup steps:

  1. Builds the metaData and widgetInput objects, consisting of information about the widget instance as well as the "input data" configured on the Widget Block respectively.
  2. Checks whether the Widget is active or inactive (Widgets can only be used once).
widgetSDK.init((event) => {
    // Perform additional setup steps in here.
    // event.type will be one of "WIDGET_INITIALIZED" or "WIDGET_INITIALIZATION_FAILED"
    // event.widgetInputs contains the input parameters for the widget


Used to submit user data from the Widget. Accepts a callback that is invoked when it completes.

Note: User data can only be sent once.

    userSelectedData: "2019-01-01 12:00:00"
}, (event) => {
    // Execute additional logic after user data is submitted.
    // event.type will be one of "SEND_USER_DATA_SUCCESS" or "SEND_USER_DATA_FAILED"

Widget SDK Events



  • widgetActive: true|false
  • metaData: An object containing information about the widget instance
  • widgetInput: An object containing the widget input data as configured in the Widget Block



  • error: The error that caused initialization to fail (ex. a network error is encountered).






  • error: The error that caused sendUserData to fail (ex. the Widget is not active).

Widget SDK Properties


Returns boolean indicating whether Widget is "active".

A value of true indicates the Widget can be used to submit user Data. The Widget be in an "active" state.

A value of false indicated the Widget is "inactive" or expired and can no longer be used to submit user data. The Widget should be in an "inactive" state (ie. it should be clear to the user that they cannot perform any action on the Widget).


Returns information about the widget instance, including the platform and chatter language. These can be used by the Widget to modify its behavior.


    platform: "chat",
    language: "en"


Contains the inputs to the widget as configured in the Widget Block. For example, the Date Picker App may be configured with a custom date format when presenting the picked date back to the user:


    dateFormat: "YY-MM-DD"


Install dependencies with yarn install.

Start dev server with yarn start. This will start a development server that watches for changes and will automatically reload itself when it has detected changes.

We use the html-webpack-plugin webpack plugin to provide an html page that loadins the script for testing/development purposes. The template is src/index.ejs and will compile to dist/index.html.

Serving over HTTPS

Widgets are passed sensitive details to enable communication back to api. Therefore, HTTPS is enforced on all Widgets.

During development, we get around this requirement by using ngrok:

ngrok http localhost:8100 -hostname=date-picker.widget.ngrok.io --host-header=rewrite


We use Karma + Jasmine for running tests.

Run with: yarn test

Karma will launch a Chrome browser to execute tests in.

In the future we will target IE11 using browserstack
