Cards Integration

Suggest Edits

PayU supports the following debit cards and credit cards:

  • American Express (AMEX)
  • Visa
  • Mastercard
  • Diners
  • Rupay

📘

Note:

PayU accepts domestic and international transactions, but international transactions need to be enabled by writing to PayU Integration Team ([email protected]).

If you are storing or transmitting cardholder data, you must fill the “Self-Assessment Questionnaire A-EP and Attestation of Compliance” form. For more information on Save Cards API integration, refer to PayU Save Cards API Integration docs.

Steps to Integrate

  1. Validate the card type
  2. Initiate the payment to PayU
  3. Check the response from PayU
  4. Verify the payment

👍

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 card type

When customers use debit cards or credit cards on your website, you can validate the card type with the first six digits. Use the check_isDomestic API (known as BIN API) to validate the type of card. For more information, refer to BIN APIs.

After the customer enters the card number, you can validate the first six digits with the check_isDomestic API. For more information, refer to Check is Domestic 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=EaE4ZO3vU4iPsp&amount=10.00&firstname=Ashish&[email protected]&phone=9876543210&productinfo=iPhone&pg=cc&bankcode=MAST&surl=https://apiplayground-response.herokuapp.com/&furl=https://apiplayground-response.herokuapp.com/&ccnum=5123456789012346&ccexpmon=05&ccexpyr=2022&ccvv=123&ccname=undefined&hash=fc3206829a6b4f8e300aeefb8f91add568b83dc90d01383a8e16553cc9600a3aefd4be2e370d32f0315ef1b9f28740515a9556b55abfefa7b54b434f894c9304"

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)
