MaMITs is Paytm payment gateway integration company, specializes for Magento, Opencart, WordPress, WooCommerce, WP eCommerce payment integration.

We know that India’s largest mobile payments and commerce platform are Paytm. This is used. for online mobile recharge and bill payments. Paytm has an online marketplace today and India’s most trusted payment platform. A payment gateway appears on the website for easy and convenient online payment. It is very helpful for the transaction, by transfer key information (like credit/debit card details) between payment portals and front-end processor/bank.

For your more convenient we describe the Detailed Payment Flow.

1. Transaction Creation
   When the transaction request is received to Paytm’s server, then there are multiple validations carried out like valid source of the request, the structure of request, uniqueness of request, etc. Once these validations are passed, then the transaction is created.
   Successful Transaction
2. After filling the basic payment details to authorize the payment. Once the authorization is successful, money is debited from the customer’s account. This transaction is a successful transaction.
3. Failed Transaction
   If the payment authorization failure, then the money is not deducted from the customer’s account. This is marked as a failed transaction.
4. Pending Transaction( https://developer.paytm.com/docs/late-notification/ )
   Sometimes Paytm doesn’t receive real-time transaction status from the bank due to many reasons like network issues, technical errors at customer’s/bank’s end, etc. This is marked as a pending transaction. Refer this for detailed handling of the pending transaction.
5. Settled Transaction
   Payments received against successful transactions are credited into your bank account on T+1, where T is the date of the successful transaction. Once the payment is credited, the corresponding transaction is marked as Settled.
6. Refund Transaction ( https://developer.paytm.com/docs/refund-management/ )
   Sometimes we need to reverse payments for successful or settled transactions. This reversal transaction of a successful or settled payment is called refund transaction.
