Integration

1. General Overview

The PayU Sample App essentially consists of three main components:

Native app: Merchants will essentially need to replace the sample app with their own app
sdkui module: That is the sample UI used by the above sample app. This is a default UI that is available for use by Merchants
Non-Seamless: In case you decide to not build your own UI, you are free to use this module
Seamless: In case you need to build your own UI, please go through this module carefully to increase your understanding of how to use SDK’s features
PayU SDK module: Consists of all the core sdk components and apis

2. Request Generation

2.1. Non-Seamless: Using SDK’s Inbuilt UI

Get all the required parameters

Create an object of PaymentParams, put all the obtained parameters in it by using its default set methods and setHash to paymentHash

  PaymentParams mPaymentParams = new PaymentParams();
  mPaymentParams.setKey(“gtKFFx”);
  mPaymentParams.setAmount(“15.0”);
  mPaymentParams.setProductInfo(“Tshirt”);
  mPaymentParams.setFirstName(“Guru”);
  mPaymentParams.setEmail(“guru@gmail.com”);
  mPaymentParams.setTxnId(“0123479543689”);
  mPaymentParams.setSurl(“https://payu.herokuapp.com/success”);
  mPaymentParams.setFurl(“https://payu.herokuapp.com/failure");
  mPaymentParams.setUdf1(“udf1l”);
  mPaymentParams.setUdf2(“udf2”);
  mPaymentParams.setUdf3(“udf3”);
  mPaymentParams.setUdf4(“udf4”);
  mPaymentParams.setUdf5(“udf5”);
  
  mPaymentParams.setHash("your payment hash");

You don't need to set udf1-5 in case you are not using them

Email and Firstname can be empty strings "" if you don't want to use them

For store user card feature
mPaymentParams.setUserCredentials("your_key:user_id"), you need to pass user_credentials here

For offers mPaymentParams.setOfferKey("your_offer_key")

For any other payment default param (like phone and others) mPaymentParams.setPhone("your_number")

Get the required hashes by using your own server. Create an object of class PayuHashes and set the corresponding hashes using the default set methods provided
```
  mPaymentParams.setHash(payuHashes.getPaymentHash());
```

Create a new intent pointing to PayUBaseActivity and do the following:

  intent.putExtra(PayuConstants.ENV, PayuConstants.PRODUCTION_ENV);  
  intent.putExtra(PayuConstants.PAYMENT_DEFAULT_PARAMS, mPaymentParams);  
  intent.putExtra(PayuConstants.PAYU_HASHES, payuHashes);

Start the activity and let PayU SDK take care of the rest
startActivity(intent);

2.2. Seamless: Using your own UI

2.2.1. Credit / Debit card

Create an object of PaymentParams, put all the obtained parameters in it by using its default set methods in the same way as you will create for the non-seamless style and setHash to paymentHash

Set the following additional properties to mPaymentParams

  mPaymentParams.setCardNumber(cardNumber);
  mPaymentParams.setCardName(cardName);
  mPaymentParams.setNameOnCard(cardName);
  mPaymentParams.setExpiryMonth(expiryMonth);// MM
  mPaymentParams.setExpiryYear(expiryYear);// YYYY  
  mPaymentParams.setCvv(cvv);

Create PaymentPostParams object with the above data of the type PostData. Make sure to set the environment (test or prod), create intent and launch the activity (PaymentsActivity if you are using PayU's webview)

  PostData postData = new PaymentPostParams(mPaymentParams, PayuConstants.CC).getPaymentPostParams();
  if (postData.getCode() == PayuErrors.NO_ERROR) {
    // launch webview
    PayuConfig payuConfig = new PayuConfig();
    payuConfig.setEnvironment(PayuConstants.PRODUCTION_ENV);
    payuConfig.setData(postData.getResult());
    Intent intent = new Intent(this,PaymentsActivity.class);
    intent.putExtra(PayuConstants.PAYU_CONFIG,payuConfig);
    startActivityForResult(intent, PayuConstants.PAYU_REQUEST_CODE);
  } else {
    // something went wrong
    Toast.makeText(this,postData.getResult(), Toast.LENGTH_LONG).show();
  }

Create an activity for Webview, in case you are not using PayU's webview activity (PaymentsActivity)

  @Override
  protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_payments);
    // initialize
    Bundle bundle =getIntent().getExtras();
    PayuConfig payuConfig =bundle.getParcelable(PayuConstants.PAYU_CONFIG);
    WebView mWebView =(WebView) findViewById(R.id.webview);
    String url =payuConfig.getEnvironment() == PayuConstants.PRODUCTION_ENV ? PayuConstants.PRODUCTION_PAYMENT_URL :PayuConstants.MOBILE_TEST_PAYMENT_URL; 
    byte[] encodedData = EncodingUtils.getBytes(payuConfig.getData(), "base64");
    mWebView.postUrl(url,encodedData);
    mWebView.getSettings().setSupportMultipleWindows(true);
    mWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.getSettings().setDomStorageEnabled(true);
    mWebView.setWebChromeClient(new WebChromeClient() {}); 
    mWebView.setWebViewClient(new WebViewClient() {});
  }

At this point you should be able to see Bank’s 3D Secure page

2.2.2. Netbanking

Create an object of PaymentParams, put all the obtained parameters in it by using its default set methods in the same way as you will create for the non-seamless style and setHash to paymentHash
Get the bankCode (String) of selected bank from your spinner/list view adapter and add it to the mPaymentParams created above
```
  mPaymentParams.setBankCode(bankCode);
```

Create PaymentPostParams object of the type PostData

  PostData postData = new PaymentPostParams(mPaymentParams, PayuConstants.NB).getPaymentPostParams();
  if (postData.getCode() == PayuErrors.NO_ERROR){
    // launch webview

    payuConfig.setEnvironment(PayuConstants.PRODUCTION_ENV);
    payuConfig.setData(postData.getResult());
    Intent intent = new Intent(this,PaymentsActivity.class); 
    intent.putExtra(PayuConstants.PAYU_CONFIG,payuConfig); 
    startActivityForResult(intent, PayuConstants.PAYU_REQUEST_CODE);
  } else {
    // something went wrong
    Toast.makeText(this,postData.getResult(), Toast.LENGTH_LONG).show(); 
  }
