VerifyMe Liveness Widget
VerifyMe has a smooth widget which helps you detect biometric spoofing attacks where a replica or imitation is presented to bypass the required identification and authentication steps
Using the VerifyMe CDN-hosted javascript client library, you can install the Liveness widget into your application. You only have to add the script tag to your html document and insert basic configuration parameters and you'll be good to go.
Include the script tag just before the end of the closing body tag of your desired html page where you wish to perform the liveness verification.
<script src="https://widget.verifyme.ng/inline.js"></script>
At this point, you can now create a Liveness widget object by passing in an object containing public key, product code and other fields containing the verification details.
new VerifyMePopupSetup({
lastname: "john",
firstname: "doe",
phone: "08128730170",
identityType: "bvn",
identityNumber: "10000000001",
key: "pk_live_ee7569XXXXXXXXXXXX9884a7cfb435",
reference: "<unique_reference>",
widgetType: "LIVENESS",
productCode: "<your product code>",
});
key (string, required)
This is the VerifyMe public key, you can find this on the dashboard
widgetType(string, required)
The
widgetType property is to signify the widget you're interested in consuming: liveness verification widget (LIVENESS) or express verification (XPRESS). In essence, the property's value could either be LIVENESS OR XPRESS.productCode (string, required)
This code is uniquely tied to the product created on your account. Kindly reach out to our customer service team to guide you through product creation.
PS: It is important to note that you can have multiple products linked to your account.
verification detailsThese are other details that are required for the liveness check verification:

On successful verification, the callback function that you supplied is called by the client library with an object as a parameter. The object contains a status field with a success value
callback: function (response) {
if (response.status == 'success') {
// [on success]
// Fetch the liveness verification status using the `response.reference` value
} else {
// [on failed]
}
}
