Wallets Integration
You can collect payments from customers with leading wallets using the Merchant Hosted integration. You need to ensure that CASH for the pg parameter and wallet code based on the desired wallet for the bankcode parameter is posted as mentioned in Collect Payment API - Merchant Hosted Checkout > Request Parameters.
Steps to Integrate
Before you begin:
Register for a account with PayU before you start integration. For more information, refer to Register for a Merchant Account.

Hashing
You must hash the request parameters using the following hash logic:
sha512(key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5||||||SALT)
For more information, refer to Generate Hash.
Sample request
curl -X \
POST "https://test.payu.in/_payment-H "accept: application/json" -H \
"Content-Type: application/x-www-form-urlencoded" -d"key=J****g&txnid=aI1UM19ONxLgPz&amount=10.00&firstname=Ashish&[email protected]&phone=9876543210&productinfo=iPhone&pg=cash&bankcode=paytm&surl=https://apiplayground-response.herokuapp.com/&furl=https://apiplayground-response.herokuapp.com/&hash=6840ba0d1a14554f7ee5d20966dfbac6b221718e72dd823f05b6da01420286315b4956c28325898b66520b111604020ea2c547608606674766eb7e4164dc0baa"
Step 3: Check response from PayU
Hash validation logic for payment response (Reverse Hashing)
While sending the response, PayU takes the exact same parameters that were sent in the request (in reverse order) to calculate the hash and returns it to you. You must verify the hash and then mark a transaction as a success or failure. This is to make sure the transaction has not tampered within the response.
The order of the parameters is similar to the following code block:
sha512(SALT|status||||||udf5|udf4|udf3|udf2|udf1|email|firstname|productinfo|amount|txnid|key)
