What is the Paytm Payment Gateway?
Paytm is one of India’s most widely used digital payment platforms, offering a payment gateway that allows businesses to accept online payments through credit cards, debit cards, net banking, UPI, and Paytm Wallet. By integrating the Paytm Payment Gateway into your Ruby on Rails application, you can provide users with a seamless and secure checkout experience. Paytm handles the payment processing, tokenization, and transaction verification, while your Rails app manages the order flow and callback handling. In this guide, we will walk through the complete integration process, from setting up your developer account to building clean service objects for payment initiation and verification.
Terms you need to know before proceeding further
MID: This is a unique identifier provided to every merchant by Paytm. MID is part of your account credentials and is different in the staging and production environments. Your staging MID is available here and production MID will be available once your activation is complete.
Merchant Key: This is a unique secret key used for secure encryption of every request. This needs to be kept on the server-side and should not be shared with anyone.
CHANNEL_ID:This parameter is used to control the theme of the payment page. Based on the channel passed, Paytm will render the layout suitable for that specific platform For websites, the value is WEB For Mobile websites/App, the value is WAP
WEBSITE: For staging environment: WEBSTAGING,
For production environment: Will be available here once your activation is completeli>INDUSTRY_TYPE_ID:For staging environment: “Retail”,For production environment: Will be available here once your activation is complete.
CALLBACK_URL:On completion of the transaction, the Paytm payment gateway will send the response on this URL. Sample URL is – https://merchant.com/callback/
Payment_url:when start payment it’s redirecting to payment gateway. In that, we can not go back or not refresh the page.
These are the steps to integrate Paytm as a payment gateway in your rails app
Step 1:Need to create developer account from here: create account
Step 2:After successful account creation, Grab below credentials from Paytm and place it inside secrets.yml or credentials.yml
Test Merchant ID = ”
Test Merchant Key = ”
Website = WEBSTAGING
Industry Type = Retail
Channel ID (For Website) = WEB
Channel ID (For Mobile Apps) = WAP
transaction_url: https://securegw-stage.paytm.in/theia/processTransaction
Step 3:We need to process and verify the payment. Create one controller named paytm_controller.rb
