Closed 4 years ago.
I am developing an Ecommerce app in which I want to integrate Payumoney payment gateway. Can someone help me with some procedure, link or tutorial, how to do so? Thanks.
I have done Perfectly :) :) You have to edit SuccessURL and FailureURL:
Its Working for Me Perfectly.

Build Custom Integration
As per payumoney: If you are building your website from scratch you need to make a post request to our
API. Pass yourkeyand othermandatory variable. This also include the Success and Failure page URL, where you wish to take your user on success and failure cases.Step 1: Create a store with any of our e-commerce platform partners.
Step 2: Choose PayUMoney as Payment option.
Step 3: Enter PayUMoney credentials and you are ready to go.
Note: You need to develop your own web services which take data from your client application and forward the request to payumoney server then take responses of callback after that your web services will notify you with result.
FlipKart, FreeCharge, Snapdeal etc they have their own url who will take responsibility to initiate the payment gateway,
So conclusion is that you need to support from your server team to initiate the payment and return the result back to your client application.
You can find the more information about payumoney and api payumoney integration,
Simplest way to integrate Payment gateway is to use a webview for your application.
You can see that most of the applications like FlipKart, FreeCharge, Snapdeal etc., use the same
This is how I did in my Application
public class PayYouMoneyFragment extends Fragment {
/** The Constant PAYU_MONEY_URL. */
private static final String PAYU_MONEY_URL = "https://www.payumoney.com/paybypayumoney/#/BCDCEAE6A98116CB48BDE55C440BC69D";
/**
* Instantiates a new pay you money fragment.
*/
public PayYouMoneyFragment() {
// Empty constructor required for fragment subclasses
}
/**
* The Class MyWebViewClient.
*/
private class MyWebViewClient extends WebViewClient {
/** The web view previous state. */
private int webViewPreviousState;
/** The page started. */
private final int PAGE_STARTED = 0x1;
/** The page redirected. */
private final int PAGE_REDIRECTED = 0x2;
/** The dialog. */
Dialog dialog = new Dialog(getActivity());
/* (non-Javadoc)

*/
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}

*/
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
webViewPreviousState = PAGE_STARTED;
if (dialog == null || !dialog.isShowing())
dialog = ProgressDialog.show(getActivity(), "",
"Loading Please Wait", true, true,
new OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
// do something
}
});
}
/* (non-Javadoc)

*/
@Override
public void onPageFinished(WebView view, String url) {
if (webViewPreviousState == PAGE_STARTED) {
dialog.dismiss();
dialog = null;
}
}
}
/** The btn back. */
Button btnBack;
/** The webview. */
WebView webview;
/* (non-Javadoc)
* @see android.support.v4.app.Fragment#onCreateView(android.view.LayoutInflater, android.view.ViewGroup, android.os.Bundle)
*/
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.payumoney_fragment, container,
false);
webview = (WebView) rootView.findViewById(R.id.payu_webview);
webview.setWebViewClient(new MyWebViewClient());
webview.getSettings().setDomStorageEnabled(true);
webview.getSettings().setJavaScriptEnabled(true);
openURL();
return rootView;
}
/**
* Opens the URL in a browser.
*/
private void openURL() {
webview.loadUrl(PAYU_MONEY_URL);
webview.requestFocus();
}
public static Fragment newInstance() {
return new PayYouMoneyFragment();
}
}
and here is payumoney layout
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/help_webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="none"
/>
I have also uploaded generalized version on Github :-

Here is a complete code guide to PayUMoney integration via web browser.

Its been tested and deployed in a real world application
