const widgetId = "3461******************38";
const tokenAuth = "125*******************TP1";

const App = () => {
    useEffect(() => {
        OTPWidget.initializeWidget(widgetId, tokenAuth); //Widget initialization
    }, [])

    const [number, setNumber] = useState('');

    const handleSendOtp = async () => {

SDK Methods

We provide methods, which helps you integrate the OTP verification within your own user interface.

getWidgetProcess is an optional method, this will receive the widget configuration data.

There are three methods sendOTP, retryOTP and verifyOTP for the otp verification process.

You can call these methods as follow:

sendOTP

The sendOTP method is used to send an OTP to an identifier. The identifier can be an email or mobile number (it must contain the country code without +). You can call this method on a button press.

NOTE: If you have enabled the invisible option in a widget configuration and you are trying to verify the mobile number with the mobile network then your number will be verified without OTP and if in any case the invisible verification gets fail in between the process then you will receive the normal OTP on your entered number.

const handleSendOtp = async () => {
  const data = {
    identifier: '91758XXXXXXX'
  }
  const response = await OTPWidget.sendOTP(data);
  console.log(response);
}

or

const handleSendOtp = async () => {
  const data = {
    identifier: '[email protected]'
  }
  const response = await OTPWidget.sendOTP(data);
  console.log(response);
}

retryOTP

The retryOTP method allows retrying the OTP on desired communication channel. retryOTP method takes optional channel code for 'SMS-11', 'VOICE-4', 'EMAIL-3', 'WHATSAPP-12' for retrying otp.

Note: If the widget uses the default configuration, don't pass the channel as argument.

const handleRetryOtp = async () => {
   const body = {
        reqId: '3463***************43931',
        retryChannel: 11 // Retry channel code (here, SMS:11)
  }
  const response = await OTPWidget.retryOTP(body);
  console.log(response);
}

verifyOTP

The verifyOTP method is used to verify an OTP entered by the user.

const handleVerifyOtp = async () => {
  const body = {
        reqId: '3463***************43931',
        otp: '****'
  }
  const response = await OTPWidget.verifyOTP(body);
  console.log(response);
}
