After demonetization in India, Paytm become more popular. Now, most of the users pay Bills and transfer money via the Paytm service. It’s very easy to use and of course very fast.

Just send or receive payment via your Mobile Phone. So, no doubt Paytm is a better service for online payment for your Website or Mobile App.
Steps to Integrate Paytm Payment Gateway in PHP
Let’s start the process of Paytm Payment Gateway Integration. It’s very easy to integrate in your application as compared to other payment gateways. Follow the below steps:
Step 1 : Register for Paytm Account
Sign Up for a Paytm business account from here: https://paytm.com/business/payments/online
During Sign up process, you need to choose the option that Paytm Payment Gateway requires for a Website or APP. Also submit a valid Redirect URL, where you want to redirect the user after successful payment received.
In the registration process, they ask for some official information like Business Types, addresses, Verification proof, Bank Details, etc. Although you can get Paytm sandbox credential without complete this process. But for production, you have to provide all required information.
After this, you will get Paytm Staging Credentials, which included Staging MID, Merchant Key, Industry Type, Website Name, and Channel ID. Paytm also send testing wallet details, which you can use for test transaction flow.
Note: All users must use Paytm with only an Indian registered number because the company hasn’t gone overseas except for Canada.
Step 2 : Download Official Paytm PHP Kit
Paytm official announced library source code in all languages. Just download Paytm Payment Gateway kit in PHP from GitHub. Extract the Zip file, there is the ‘PaytmKit’ folder which has all required files.
Step 3: Configure Paytm Credential
Open ‘config_paytm.php’ file in PaytmKit -> lib folder and update with the access credential you got from Paytm.

define('PAYTM_ENVIRONMENT', 'TEST'); // change value PROD for production define('PAYTM_MERCHANT_KEY', 'vsbi51****uKL0#3 '); define('PAYTM_MERCHANT_MID', 'codefi*****858443'); define('PAYTM_MERCHANT_WEBSITE', 'WEBS***ING'); |
By default source code ready for staging site. When you want to move to Production update the ‘PAYTM_ENVIRONMENT’ value by ‘PROD’.
Step 4: Create HTML Payment Form
After configuring the credential, your code is ready to process. Now create an HTML form to make the online transactions.
Form action should be to this file ‘pgRedirect.php’ inside PaytmKit folder. This file handle checksum and other require details and redirect to you Paytm payment page. After click on checkout button user can process the payment via the paytm wallet.

I have tried this but the data not getting on the response page because I have to send data to the database from the response page.
