    },
    "deviceInformation": {
        "httpBrowserLanguage":"en-US",
        "httpBrowserJavaEnabled":false,
        "httpBrowserJavaScriptEnabled":true,
        "httpBrowserColorDepth":24,

See sample response for each scenario. An extra mandatory object parameter(deviceInformation) is required to capture the user’s device information.

Info

 Info
From the above response, the redirectUrl similar to the ascUrl is the url that takes the user to the VISA card website that has an input form to enter OTP sent to the user's phone number.
For those using the API method, the backend sends the ascUrl, TermUrl,md and the jwt response parameters to the frontend which runs an onload html form that redirects the user to VISA website.
 Code Block
languagehtml
<body onload ='form1.submit()'>
    <form id="form1" action=ACSUrl method="post">
      <input name="TermUrl" value={TermUrl}>
      <input name="MD" value={MD}>
      <input name="JWT" value={jwt}>
    </form>
</body>
Frontend posts an Html form that redirects to the VISA card website to collect OTP sent to the user’s phone. After the OTP verification is completed on the VISA card endpoint, it makes a post request to the callback URL, which is similar to what is given in the TermUrl(It’s also possible to replace the TermUrl with your own URL so as to know when OTP verification process ends).
Finally, to authorize the charge on the user’s card, you make an authenticated post request (containing your transaction reference, collection channel, api key, and card details) to the authorized endpoint. Check 3DS Secure Authentication on how to authorize the charge.
