@ajitpatel28/react-native-truecaller

React Native library for seamless Truecaller integration, supporting Android SDK v3.0.1 and iOS SDK v0.1.8

Features

• Easy integration with Truecaller SDK for both Android and iOS
• Customizable UI options for Android
• Simplified user authentication flow
• TypeScript support

Installation

npm install @ajitpatel28/react-native-truecaller
# or
yarn add @ajitpatel28/react-native-truecaller

Setup

iOS Setup

To generate a client ID, follow the instructions in the Truecaller IOS Guide.

1. Add the following to your Podfile:

pod '@ajitpatel28/react-native-truecaller', :path => '../node_modules/@ajitpatel28/react-native-truecaller'

2. Run pod install in your iOS directory.

3. In your iOS project, add URL schemes for Truecaller in your Info.plist:

<key>CFBundleURLTypes</key>
<array>
<dict>
  <key>CFBundleURLSchemes</key>
  <array>
    <string>truecallersdk-{YOUR_APP_ID}</string>
  </array>
</dict>
</array>

Replace {YOUR_APP_ID} with your actual Truecaller App ID.

4. Add the truesdk entry under LSApplicationQueriesSchemes in your Info.plist file:

<key>LSApplicationQueriesSchemes</key>
<array>
<string>truesdk</string>
</array>

5. Add the associated domain provided by Truecaller:

• In Xcode, go to your project's target
• Select the "Signing & Capabilities" tab
• Click on "+ Capability" and add "Associated Domains"
• Add the domain provided by Truecaller with the "applinks:" prefix

For example: applinks:your-provided-domain.com

Note: Do not include "http://" or "https://" in the domain.

Android Setup

To generate a client ID, follow the instructions in the Truecaller Android Guide.

1. Add the Truecaller SDK client ID to your AndroidManifest.xml file inside the <application> tag:

<meta-data
  android:name="com.truecaller.android.sdk.ClientId"
  android:value="YOUR_CLIENT_ID"/>

Replace YOUR_CLIENT_ID with your actual Truecaller client ID.

2. Ensure your app has the INTERNET permission in the AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET" />

Usage

import React, { useEffect } from 'react';
import { View, Button } from 'react-native';
import { useTruecaller } from '@ajitpatel28/react-native-truecaller';
const TruecallerLoginComponent = () => {
  const {
    initializeSDK,
    openTruecallerForVerification,
    userProfile,
    error
  } = useTruecaller({
    androidClientId: 'YOUR_ANDROID_CLIENT_ID',
    iosAppKey: 'YOUR_IOS_APP_KEY',
    iosAppLink: 'YOUR_IOS_APP_LINK',
  });
  useEffect(() => {
// Initialize the Truecaller SDK when the component mounts
    initializeSDK();
  }, []);
  const handleTruecallerLogin = async () => {
    try {
      await openTruecallerForVerification();
// The userProfile will be updated automatically if verification is successful
    } catch (err) {
      console.error('Truecaller login error:', err);
// Handle error
    }
  };
  useEffect(() => {
    if (userProfile) {
      console.log('Truecaller profile:', userProfile);
// Handle successful login, e.g., navigate to a new screen or update app state
    }
  }, [userProfile]);
  useEffect(() => {
    if (error) {
      console.error('Truecaller error:', error);
// Handle error, e.g., show an error message to the user
    }
  }, [error]);
  return (
    <View>
      <Button title="Login with Truecaller" onPress={handleTruecallerLogin} />
  </View>
);
};
export default TruecallerLoginComponent;
