JavaScript Library for Web Verification

How to Generate Widget Using the Dojah CDN-hosted Javascript client library, you can install the Dojah widget into your application by simply adding a script tag to your HTML document and insert basic configuration parameters. Step 1: Add the Client Javascript Library Add the script tag before the end of the closing body tag of your desired HTML page where you desire to give users the ability to authorize access to a financial institution.

javascript

<script src="https://widget.dojah.io/widget.js"></script>

Adding the async attribute can cause the inline code to return undefined because the library may not be available at that moment. So avoid the use of async and defer for now.

Step 2: Configure the Javascript Client Library At this stage, you can now create a Dojah widget object by passing in your public key in javascript object representing your preferred configuration options.

javascript

const options = {
  app_id: app_id, //your app_id here
  p_key: p_key, //your production public key here
  type: 'custom',
  user_data: {
    first_name: {$first_name}, //optional
    last_name: {$last_name}, //optional
    dob: {$dob}, //YYYY-MM-DD Optional
    residence_country: 'NG', //optional
    email: {$email}//optional
  },
  gov_data : {
    "bvn": "123456789", //
    "nin": "123456789", //
  },
  metadata: {
    user_id: '12xxxxsxsxsxssx1',
  },
  
  config: {
    widget_id: ""  //this is generated from easyonboard here https://app.dojah.io/easy-onboard

  },
  onSuccess: function (response) {
    console.log('Success', response);
  },
  onError: function (err) {
    console.log('Error', err);
  },
  onClose: function () {
    console.log('Widget closed');
  }
};

const connect = new Connect(options);
const button = document.querySelector('#button-connect');
button.addEventListener('click', function () {
  connect.setup();
  connect.open();
});

Parameter	Type	Description
type	string	Widget Type: Values are ‘custom’, ‘verification’, ‘identification’, ‘verification’, ‘liveness’
app_id	string	Application Id, Get it from your dojah application dashboard here
p_key	string	Public Key, Get it from your dojah application dashboard here
reference_id	string	Reference ID, It can be passed to keep track of the verification steps (Started, Ongoing, Successful). NB: reference_id character length must be greater than 10
widget_id	string	Widget ID, Get it from your Easy Onboard application dashboard here
user_data	object	Automatically update the user data page, and thus skip the page
gov_data	object	Automatically update the government data page, and thus skip the page
metadata	object	Your application’s metadata to be passed back to you via webhook, onSuccess, or onError
onSuccess	function	This is called when your user has successfully completed enrollment with their preferred institution. The sample response data below is passed to the widget
onError	function	This is called when your user was unable to successfully complete enrollment.
onClose	function	This is called when the widget is closed.

Important Security Update: Proper Handling of SDK Verification CallbacksThe final verification decision should never rely on SDK callbacks (onSuccess, onError, onClose) alone. Always retrieve the actual verification status from your backend using the reference ID before granting access or approving onboarding.

onSuccess — What it really means

The onSuccess callback only confirms that the user has completed the verification flow on the widget. It does not mean the user passed all verification checks.For example, a user might complete the process but still fail a document validation, liveness check, or other verification step. Relying only on onSuccess to approve a user can lead to incorrect verification decisions.

onError — When errors occur

The onError callback is triggered when an error occurs during the verification process. This could be due to:

Network issues
SDK initialization problems
Configuration errors
An interruption during the verification flow

When this occurs, the verification process is not completed successfully and should be handled appropriately in your application.

onClose — Widget closed behavior

Recommended ImplementationAfter the widget interaction, create a backend flow or confirmation page that retrieves the actual verification result using the reference ID generated during the verification process. You can retrieve the final verification details through:

Webhook notifications — Subscribe to services
Verification Details API — Get verification details

Possible Verification Statuses The verification result returned by the webhook or API may contain any of the following statuses:

Status	Description
Ongoing	The verification process is currently in progress.
Completed	The verification has been successfully completed and passed all checks.
Pending	The verification is awaiting further action or review.
Failed	The verification was completed but did not pass one or more verification checks.
Abandoned	The verification was started but not completed by the user.

Typescript implementation

If you want to use typescript on some classes that are not available now or in the future, you could look at extending the global ‘window’ interface. You can follow below steps to guide you: With typescript, you need to extend the global Window interface with additional properties. Create a new folder “types” Add a file “index.d.ts” Put below code inside your “index.d.ts” file

typescript

export { };
declare global {
    interface Window {
        Connect: any;
	//add more properties you would like to extend
    }
}

set your compilerOptions “typeRoots” property to path of your type folder E.g [”./src/types”] Use the extended window property anywhere like this:

typescript

const connect = new window.Connect(options);

Step 3: Handle a Successful Verification On successful enrollment, the onSuccess callback function that you supplied is called by the client library. We then return the connected account code to your server. Kindly use the overall status (response.status (Boolean, i.e true or false)) to ascertain if the request failed or succeeded.

Webhook NotificationsYou can receive the same data below (also passed to onSuccess and onError) via a webhook call.Register your url for webhook calls here and ensure kyc.widget is the service you are subscribed to.In Config object Kindly set webhook object value to true (Boolean)Example : webhook : true
