Understanding account credentials
Account credentials are available in your dashboard for both staging and production environments. These credentials consist of the following:
MID (Merchant ID) - This is a unique identifier provided by Paytm to every merchant. MID is part of your account credentials and is different in 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 server-side and should not be shared with anyone.
The Paytm Dashboard is a single window to manage your account:

Fundamentals of collecting payments with Paytm
Your customer clicks the Pay button in your web/mobile application.
The customer is shown a checkout form where she fills in 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 the customer.

Detailed Payment Flow Explained
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.
The customer fills in 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.
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.
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 to this for detailed handling of the pending 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.
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.
