UPI TPV Integration - PayU Hosted Checkout

For UPI integration, you need to post transaction details to PayU with beneficiary details for validation, similar to Net-Banking integration.

The request parameters for UPI integration are the same as Net-Banking integration. The beneficiarydetail parameter should include the UPI beneficiary details.

Environment

The following environments are available for TPV integration:


Test Environment	https://test.payu.in/_payment
Production Environment	https://secure.payu.in/_payment

Step 1: Create transaction with beneficiary details

Create a transaction by including a JSON object with beneficiary details (account numbers and IFSC codes). You can include up to 4 accounts for validation.

Step 2: Post the parameters to PayU

Request parameters

Parameter	Description	Example
key `mandatory`	`String` Merchant key provided by PayU during onboarding	JPg***r
txnid `mandatory`	`String` The transaction ID is a unique reference for each order. Duplicate transaction IDs are not allowed.	ypl938459435
amount `mandatory`	`String` Transaction amount	100
productinfo `mandatory`	`String` Product description	Test Product
firstname `mandatory`	`String` Customer's first name	John
email `mandatory`	`String` Customer's email address	[email protected]
phone `mandatory`	`String` Customer's phone number	9999999999
beneficiarydetail `mandatory`	`String` JSON object that contains account numbers and corresponding IFSC codes (max 4 accounts) in the same order	beneficiarydetail JSON Object Fields
surl `mandatory`	`String` Success URL - PayU will make a POST request with transaction response to this URL if the transaction is successful	https://www.yoursurl.com
furl `mandatory`	`String` Failure URL - PayU will make a POST request with transaction response to this URL if the transaction fails	https://www.yourfurl.com
api_version `mandatory`	`String` Version of the API	6
hash `mandatory`	`String` SHA512 hash calculated using the formula: sha512(key\|txnid\|amount\|productinfo\| firstname\|email\|udf1\|udf2\|udf3\|udf4\|udf5\|\|\|\|\|\| beneficiarydetail\|SALT)

📘
Hash calculation
The hash is calculated using the following formula:
sha512(key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5||||||beneficiarydetail|SALT)
Replace SALT with the salt value provided during onboarding.

beneficiarydetail JSON object fields

The beneficiarydetail parameter should be a JSON object with the following structure:

Field	Description	Example
beneficiaryAccountNumber	`String` List of account numbers separated by pipe symbol (\|). Maximum 4 accounts.	"002001600674\| 00000031957292212\| 00000035955239352\| 00000035955239352"
ifscCode	`String` List of corresponding IFSC codes separated by pipe symbol (\|). Maximum 4 IFSC codes in the same order as account numbers.	"KTKB0000046\| KTKB0000023\| KTKB0000035\| KTKB0000035"

Example JSON:

{
  "beneficiaryAccountNumber": "002001600674|00000031957292212|00000035955239352|00000035955239352",
  "ifscCode": "KTKB0000046|KTKB0000023|KTKB0000035|KTKB0000035"
}

📘
beneficiarydetail parameter in hashing:

The beneficiarydetail parameter must be included in the hash calculation.

The format should be exactly as shown in the hash formula above.

Replace SALT with the salt value provided to you during onboarding.

Step 3: Check the response from PayU

After posting the parameters, PayU will return a response with transaction details.

Hash Validation Logic for payment response (Reverse Hashing)

To validate the authenticity of the response, you can calculate the reverse hash using:

sha512(SALT|status||||||udf5|udf4|udf3|udf2|udf1|email|firstname|productinfo|amount|txnid|key)

📘
beneficiarydetail parameter not required in reverse hashing:
The beneficiarydetail parameter is not required when calculating the reverse hash.
