Sample code :-https://github.com/Paytm-Payments/Pay... APi and code :-http://paywithpaytm.com/developer/pay... Once the customer clicks on Paytm Wallet option, then a request is made to the merchant’s internal server to fetch a newly created CheckSum Hash (The method of creating CheckSum Hash is given below in the “Generating Checksum” section). Once the CheckSum Hash is received, then the customer is temporarily redirected to Paytm’s Payment Gateway page (Paytm Wallet transactions too are routed through Paytm’s Payment Gateway). In order for this to happen, the merchant’s web server needs to raise a transaction request to Paytm’s server which requires POSTing an HTML form with the required fields as explained in the Request parameters table in the description below. If the customer has sufficient amount in his wallet, then he can complete the transaction by simply clicking on the Pay button. Paytm then POSTs the transaction status to the call-back URL provided by the merchant. Again, the merchant has to verify the Checksum for this transaction status using the provided Server Side Utilities for Checksum. Merchant can present this transaction result to the customer on their website/app. In case of insufficient wallet balance, the customer is presented with options of completing the transaction using different payment options like credit card, debit card or net banking. The user is then redirected to bank’s 3D secure page for further authentication. Upon authentication of transaction by bank, Paytm receives the response sent by the bank and POSTs it to the callback URL provided by the merchant. Merchant then reads the response parameters sent by Paytm and presents the transaction result to the customer on his own website/app. Android and iOS Integration Paytm provides Android and iOS SDKs for integrating Paytm Wallet with apps. The SDK and it’s documentation can be found here. The SDK will call the necessary APIs and make your integration process extremely simple. Alongwith the SDK, a Checksum generation module needs to be setup on the merchant’s server. The Server Side Utilities for checksum are available here and the details of the module are given below in the APIs section of this document. APIs Description This section details the APIs you need to work with to take payments on your app/website using Paytm Wallet and for handling operational issues related to payments (eg: refunds, transaction status check). Please make sure you visit the MOBILE INTEGRATION and WEB INTEGRATION sections of this document to see if there are pre-built solutions for your development platform. Using these solutions might reduce your need to understand the API documentation given below and significantly cut down on development effort at your end. Transaction Request API Merchant needs to post the request parameters on the Payment Gateway URLs that are given below. Dynamic & unique Order_ID (explained in table below) needs to be appended to each request as shown. Below are Payment Gateway URL’s: Staging: https://pguat.paytm.com/oltp-web/proc...
