Step 1: Register Paytm Account

First we need to Sign Up for a Paytm business account from here: https://paytm.com/business/payments/online

During creating Paytm business account 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 this 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 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: Setup Paytm Credentials

For configuration the paytm credentials in php you need to 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****uKL333 ');
define('PAYTM_MERCHANT_MID', 'codefi*****858343');
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 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 page-redirect.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.
