UPI Integration
PayU allows you to collect payments using UPI handles. For the list of UPI providers supported, refer to UPI Handles.
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.
Step 1: Validate the UPI handle
When your customer makes payment through UPI, you can validate the customer’s Virtual Payment Address (VPA) and then initiate payment. The validateVpa API is used to validate the UPI handle. Validate the VPA (UPI handle) using the validateVpa API. For more information, refer to Validate VPA Handle API.
Step 2: Initiate the payment to PayU

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=JP***g&txnid=xdB9G7qYpfqszo&amount=10&firstname=PayU User&[email protected]&phone=9876543210&productinfo=iPhone&pg=UPI&bankcode=UPI&vpa=VPA-anything@payu&surl=https://apiplayground-response.herokuapp.com/&furl=https://apiplayground-response.herokuapp.com/&hash=649bc87e0e8ee7bbd1e930d43c99a9165eb9fa7a3f4542a33e8d66bd207a63d631708fd9781e56b133581f7dabeaa67baa5609d5e5c9990f986792d59e7d41cb"
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)
