How to integrate paytm wallet in android application?

• I want to integrate paytm wallet in my android application. I find lots of documentations on google but didn't get anything. Is there any documentation, code sample that you know please inform me. Thanks in advance.

• Answer:

  Go to link : http://paywithpaytm.com/developer.html and download Android+SDK put below code in your function or where you want to start paytm stuff. private int randomInt = 0; private PaytmPGService Service = null; Random randomGenerator = new Random(); randomInt = randomGenerator.nextInt(1000); //for testing environment Service = PaytmPGService.getStagingService(); //for production environment /*Service = PaytmPGService.getProductionService();*/ /*PaytmMerchant constructor takes two parameters 1) Checksum generation url 2) Checksum verification url Merchant should replace the below values with his values*/ PaytmMerchant Merchant = new PaytmMerchant("https://pguat.paytm.com/merchant-chksum/ChecksumGenerator","https://pguat.paytm.com/merchant-chksum/ValidateChksum"); //below parameter map is required to construct PaytmOrder object, Merchant should replace below map values with his own values Map<String, String> paramMap = new HashMap<String, String>(); //these are mandatory parameters paramMap.put("REQUEST_TYPE", "DEFAULT"); paramMap.put("ORDER_ID", String.valueOf(randomInt)); //MID provided by paytm paramMap.put("MID", "id provided by paytm"); paramMap.put("CUST_ID", "CUST123"); paramMap.put("CHANNEL_ID", "WAP"); paramMap.put("INDUSTRY_TYPE_ID", "Retail"); paramMap.put("WEBSITE", "paytm"); paramMap.put("TXN_AMOUNT", "1"); paramMap.put("THEME", "merchant"); PaytmOrder Order = new PaytmOrder(paramMap); Service.initialize(Order, Merchant,null); Service.startPaymentTransaction(activity, false, false, new PaytmPaymentTransactionCallback() { @Override public void onTransactionSuccess(Bundle bundle) { app.getLogger().error("Transaction Success :" + bundle); } @Override public void onTransactionFailure(String s, Bundle bundle) { app.getLogger().error("Transaction Failure :" + s + "\n" + bundle); } @Override public void networkNotAvailable() { app.getLogger().error("network unavailable :"); } @Override public void clientAuthenticationFailed(String s) { app.getLogger().error("clientAuthenticationFailed :" + s); } @Override public void someUIErrorOccurred(String s) { app.getLogger().error("someUIErrorOccurred :" + s); } @Override public void onErrorLoadingWebPage(int i, String s, String s2) { app.getLogger().error("errorLoadingWebPage :" + i + "\n" + s + "\n" + s2); } }); } Also another thing is you need to declare one activity in AndroidManifest.xml file: <activity android:name="com.paytm.pgsdk.PaytmPGActivity" android:theme="@style/AppTheme" android:screenOrientation="portrait" android:windowSoftInputMode="stateHidden"/> Hope above code sample will help u lot. Also another thing is when you download Android+SDK you will get one jar file pgsdk.jar file that you need to add in your project and MainActivity.java class file for our reference. Enjoy!!! Note: ChecksumGenerator and ValidateChksum urls are for just testing purpose which is provided by paytm development support team
