Start Building with Paytm

Paytm Payment Gateway provides a secure, PCI-compliant way to accept Debit/Credit card, Net-Banking, UPI and Paytm wallet payments from your customers.

Understanding account credentials

Account credentials are available in your dashboard for both staging and production environment. These credentials consist of the following:

  • MID (Merchant ID) - This is a unique identifier provided to every merchant by Paytm. MID is part of your account credentials and is different on staging and production environment. 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 server-side and should not be shared with anyone.


The Paytm Dashboard is a single window to manage your account:

  • Activate account to start accepting payments

  • Generate your staging and production account credentials

  • Switch views between staging and production transaction data

  • Check payments received from your customers

  • Check bank transfers Paytm makes into your account

  • Initiate refunds if you need to

  • Download all kinds of transaction reports

  • Get help

Fundamentals of collecting payments with Paytm

  • Your customer clicks the Pay button in your web/mobile application.

  • Customer is shown a checkout form where she fills her payment details and authorizes the payment.

  • After completion of a transaction, Paytm posts the response (success or failed) on a Callback URL defined by you.

  • As a recommended security measure, you validate each transaction response via a server-to-server (S2S) API call. Transaction revalidation protects from request/response tampering possible in-browser calls. This S2S call is not required for Paytm plugins and hosted e-commerce website integration solutions.

  • Based on the response received, you display the order status to customer.

  • See a real-time summary of payments received and other insights in your dashboard.

  • Receive payments collected from customers in your bank account on next business day.

Detailed Payment Flow Explained

Transaction Creation

When a transaction request is received at Paytm's server, 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, a transaction is created.

Successful Transaction

Customer fills 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.

Failed Transaction

If the customer drops out from the payment process, or in the event of payment authorization failure, money is not deducted from the customer’s account. This is marked as a failed transaction.

Pending Transaction

Sometimes Paytm doesn't receive real-time transaction status from the bank. This can be due to many reasons such as 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.

Settled Transaction

Payments received against successful transactions are credited into your bank account on T+1, where T is the date of a successful transaction. Once the payment is credited, the corresponding transaction is marked as Settled.

Refund Transaction

Sometimes there are use cases where you need to reverse payments for successful or settled transactions. The reversal transaction of a successful or settled payment is called a refund transaction. Refer Refunds for more details.
