This library depends on react-native-webview.
We also offer Expose Methods to integrate the OTP widget within your own User Interface.
`jsx
import React, { useState } from 'react';
import { Modal, SafeAreaView, StyleSheet, Text, TouchableOpacity } from 'react-native';
import { OTPVerification } from '@msg91comm/react-native-sendotp';
const App = () => {
const [isModalVisible, setModalVisible] = useState(false);
return (
onCompletion={(data) => {
console.log(data) // Get your response of success/failure.
setModalVisible(false)
}}
widgetId={'Paste your widgetId here'} // Get widgetId from MSG91 OTP Widget Configuration
authToken={'Paste your authToken here'} // Get authToken from MSG91 OTP Tokens
/>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center'
},
button: {
backgroundColor: '#C0EDD2',
borderRadius: 8,
alignItems: 'center',
justifyContent: 'center',
padding: 12,

We provide expose methods, which helps you integrate the OTP verification within your own user interface.
The installation process is same as above.
Import the ExposeOTPVerification component:
`jsx`
import { ExposeOTPVerification } from '@msg91comm/react-native-sendotp';
Create a ref:
`jsx`
const ExposeOTPVerificationRef = createRef
Assign the ref to component and pass the widgetId and authToken:
`jsx
return(
// Your screen code goes here...
authToken={authToken}
widgetId={widgetId}
getWidgetData={(widgetData) => { // You will receive the widget configuration data here
console.log('Widget Data', widgetData) // eg. OTP length, retry time, allowed retries etc.
}}
/>
)
` is an optional prop, 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:
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.
`jsx`
const handleSendOtp = async () => {
const response = await ExposeOTPVerificationRef.current?.sendOtp('example@xyz.com');
console.log(response);
}
orjsx`
const handleSendOtp = async () => {
const response = await ExposeOTPVerificationRef.current?.sendOtp('919999999999');
console.log(response);
}
The retryOtp method allows retrying the OTP on desired communication channel.
retryOtp method takes optional channel as 'SMS', 'VOICE', 'EMAIL', 'WHATSAPP' for retrying otp.
Note: If the widget uses the default configuration, don't pass the channel as argument.
`jsx`
const handleRetryOtp = async () => {
const response = await ExposeOTPVerificationRef.current?.retryOtp('SMS');
console.log(response);
}
The verifyOtp method is used to verify an OTP entered by the user.
`jsx`
const handleVerifyOtp = async () => {
const response = await ExposeOTPVerificationRef.current?.verifyOtp(123456);
console.log(response);
}
