• Add new RNPayUPackage() to the list returned by the getPackages() method

1. Append the following lines to android/settings.gradle:

   include ':react-native-payu'
   project(':react-native-payu').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-payu/android')
   

2. Insert the following lines inside the dependencies block in

   android/app/build.gradle:

   implementation project(':react-native-payu')
   

Usage

1. Get PayU data:

   Create your Merchant account in PayU website. https://www.payu.in
   
   Under Profile you will get your Merchant ID
   
   Under DASHBOARD you will get Merchnat KEY and SALT Key.
   
   Also Test Card details are available which can be used for testing.
   

2. Import PayUMoneyLib module to your component:

   import PayUMoneyLib from 'react-native-payu';
   

3. Call PayU() method with the payment options. Method returns a Promise

const payUData = {
    amount: '100',
    txnId: '642346786768',
    productName: 'product_name',
    firstName: 'First Name',
    email: '[e-mail]',
    phone: '9444444444',  //Number should be valid in test mode also
    merchantId: 'Your Merchant Id',
    key: 'Your Merchant Key',
    successUrl: 'Your success URL or success webhook URL',
    failedUrl: 'Your failed URL or failed webhook URL',
    isSandox: true,  //In case of production or Live set false
    hash:'Hash Code' //You can check it below how to generate hash code,
}
// You can also add udf1 to udf10 for additional info
 
PayU.startPayment(payUData).then((data) => {
    // Payment Success
    if (data.status){
        // Payment Success
        console.log('PAYMENT_SUCCESS', data.payUResponse);
    }else{
       // Payment Failed
        console.log('PAYMENT_FAILED', data.error_message);
    }
}).catch((e) => {
    // Payment Failed
    console.log("PAYMENT_FAILED",e);
});

### Validating Hash

Don't use in production just for testing purpose

PayU.getHash({
    key: "Your Merchent Key",
    amount: "100",
    email: "[e-mail]",
    txnId: "642346786768",
    productName: "product_name",
    firstName: "Your First Name",
    salt: "Salt"
});
 
// output: 43dfxcvdxd345tre534g545gb54e4g646h7nfgr35e060c3bfc0e489290e7c902750d5db3fc8be2f180daf4d534d7b9bef46fa0158a4c8a057b61

Server side function to get Hash Code

function payUHash(payUData){
    const hashString = `${payUData.key}|${payUData.txnId}|${payUData.amount}|${payUData.productName}|${payUData.firstName}|${payUData.email}|${payUData.udf1}|${payUData.udf2}|${payUData.udf3}|${payUData.udf4}|${payUData.udf5}|${payUData.udf6}|${payUData.udf7}|${payUData.udf8}|${payUData.udf9}|${payUData.udf10}|${payUData.salt}`;
    //In case you are not passing udf values then set it as empty string 
    return sha512(hashString);
}
 

### Troubleshooting

Below is the test card details for transaction in the testing mode.

  Card No - 5123 4567 8901 2346
  Expiry - 11/22 // any future date
  CVV - 123
  OTP - 123456
